How to Get Rid of Squirrels in the Loft and Stop Them Coming Back

If you are trying to work out how to get rid of squirrels in the loft, the most reliable long-term approach is usually to deal with the squirrels currently using the roof space, establish how they are getting in, and then secure the relevant entry points. Inoculand provides professional squirrel control in London for properties where the activity, access or roof structure makes this difficult to resolve safely without specialist help.
The order matters. Sealing an opening while a squirrel or dependent young remain inside can create a new problem rather than solving the existing one. A professional inspection can establish whether squirrels are still occupying the roof, where they are likely to be entering and whether treatment, proofing or both are required.
This guide explains the signs to look for, what squirrel sounds in a loft can tell you, how professional treatment works, when traps may form part of the programme, and what can make a squirrel problem more complicated than it first appears.
This guide explains how to recognise squirrel activity, what loft noises can tell you, how professional squirrel treatment works, when traps may form part of the programme, why proofing usually comes last, and what can make a squirrel problem more complicated than it first appears.
How to get rid of squirrels in the loft: the short answer
For most homes, how to get rid of squirrels comes down to a controlled sequence: confirm the pest, inspect the roof space, resolve the current activity, confirm that the evidence supports closure, and then complete suitable proofing.
- The most dependable way to get rid of squirrels is to resolve the current activity and then secure the access route.
- Grey squirrels are mainly active during daylight, so heavy movement around dawn or during the day can provide an important clue.
- Professional treatment should start with inspection and diagnosis rather than assuming that every loft noise comes from squirrels.
- Where trapping is appropriate, pre-baiting gives squirrels time to find and accept the treatment station before the active trapping period begins.
- Once a technician activates a trap, the business needs a planned inspection regime rather than an open-ended trapping period.
- Proofing should only proceed when the evidence supports closure and the technician has considered any protected-species concerns, particularly bats.
Professional squirrel control therefore has two connected objectives:
- resolve the squirrels currently occupying or repeatedly entering the loft; and
- identify and secure the structural route that allowed the problem to develop.
If you remove the current squirrels but leave a usable entry point open, another squirrel may use the same route later.
Why squirrels get into lofts and roof spaces
Lofts offer shelter from weather, nesting space, insulation and relative protection from disturbance. Grey squirrels do not hibernate, so activity can continue through colder months. Our guide to winter pest control explains why several pests continue causing problems inside buildings during winter.
In many homes, squirrels exploit an existing weakness rather than create an entirely new opening. Gaps around eaves, damaged fascia boards, deteriorated soffits, displaced roof materials and junctions between different roof sections can all provide access.
Squirrels can enlarge vulnerable areas by gnawing. Trees and adjoining structures may make the roof easier to reach, but removing a convenient branch does not remove the need to repair a viable entry point.
Breeding also matters. A roof space may contain a drey and dependent young. The calendar alone cannot confirm that, so the technician needs to assess the evidence at the property before trapping, exclusion or permanent proofing.
Are squirrels nocturnal?
No. Grey squirrels are primarily active during daylight. Homeowners often notice them around the beginning of the day, although activity can occur at other daylight hours.
This makes timing useful when trying to distinguish squirrels from other pests. Repeated heavy movement in the roof around dawn can support a squirrel diagnosis, while light scratching during the night may point more towards mice or rats.
Timing only provides a clue. Building materials can transmit noise over surprising distances, and birds, rodents and squirrels can sometimes use the same roof structure at different times. A physical inspection therefore gives a more reliable basis for diagnosis than sound alone.
What squirrel sounds in the loft usually mean
Squirrels are substantially larger than mice, so their movement can sound heavier. Customers often describe thumping, rapid scampering, scratching or movement across the ceiling.
Useful questions include:
- Does the noise mainly occur during daylight?
- Does it happen around dawn?
- Does it sound like a relatively heavy animal moving across the roof structure?
- Does it repeatedly come from the same part of the loft?
- Has anyone seen a squirrel entering or leaving the roof?
A very loud noise does not automatically mean that several squirrels are present. Equally, a quieter problem does not rule them out. The technician should compare the acoustic pattern with the physical evidence found during inspection.
Signs of squirrels in the loft and attic
Once the technician gains access, they look for a combination of signs rather than relying on one feature.
Possible evidence includes:
- runs or channels through disturbed loft insulation;
- nesting material or a drey within insulation or eaves;
- droppings consistent with squirrel activity;
- gnawing to timber or other building materials;
- damaged insulation;
- chewed electrical cables;
- daylight around vulnerable sections of the eaves; and
- an external opening that corresponds with activity inside.
An important inspection point: roof spaces often contain historical evidence from more than one pest. Old mouse droppings or bird feathers do not automatically explain the activity the customer hears now. The technician should keep investigating until the available evidence gives a coherent picture.
Some damage only becomes apparent after a loft inspection. Electrical cable damage deserves particular attention because visible gnawing may justify assessment by a competent electrician. If the technician finds significant deterioration of structural timber, an appropriate building professional should assess it.
What happens during a professional squirrel inspection?
The investigation often begins before the technician arrives. The office can gather information about the noise, sightings, property layout, loft access and roof height so that the team can book the right type of visit.
Useful information includes:
- whether there is an internal loft hatch;
- where the hatch is positioned;
- whether the roof contains extensions or converted areas;
- whether some ceiling voids have no access panel;
- the approximate height and shape of the roofline;
- whether front and rear access are available; and
- whether the customer has ever seen bats emerging from or using the roof.
Photographs can help with preparation, but they do not always show the full geometry of a roof or the practical limitations created by extensions, conservatories, neighbouring boundaries or sloping ground.
Opening and inspecting the loft safely
A technician should open an unfamiliar loft cautiously because loose insulation, twigs or other material may sit close to the hatch.
From the access point, a strong torch often allows useful initial observations. The technician can assess the immediate structure, look for live wildlife and decide whether moving further into the loft is justified and safe.
There is no benefit in crawling unnecessarily across unboarded or difficult roof spaces just to say that every corner has been entered. The inspection should follow the available evidence while respecting the limitations of the building.
How to get rid of squirrels starts with understanding the access points
Anyone considering how to get rid of squirrels needs to think beyond the animal currently making the noise. The technician also needs to understand how the roof is being accessed.
Common areas requiring attention can include:
- fascia and soffit junctions;
- gaps around eaves;
- damaged or deteriorated roof materials;
- junctions between extensions and the original building;
- dormers and complicated roof intersections;
- openings around gutter lines; and
- connected roof spaces in terraces or divided buildings.
Converted lofts can be particularly difficult because the visible room may sit between narrow inaccessible voids. Activity heard beside a bedroom ceiling may therefore come from a lower sloping roof section rather than the main accessible loft.
What if there is no loft hatch?
No internal hatch does not automatically make treatment impossible, but it changes the assessment. Another access point may exist, including a communal roof hatch in some buildings. In other cases, a competent trade may need to create a suitable access panel.
An external investigation may also help identify the relevant fascia or eave defect. Where work at height is necessary, the team should select the access method from the site-specific risk assessment rather than defaulting to one ladder type for every property.
How to get rid of squirrels with a four-visit treatment programme
Our revised approach to how to get rid of squirrels separates pre-baiting from the short period during which traps are active. This gives squirrels time to find the treatment stations without leaving active trapping equipment operating for an unnecessarily long period.
Visit 1: inspection and pre-baiting
The technician confirms the available evidence, assesses the accessible roof space, considers non-target and protected-species concerns, and identifies likely movement and entry routes.
Where mechanical trapping is appropriate, the technician positions suitable treatment stations and adds bait. The spring traps remain unset and incapable of capture during this stage.
Pre-baiting matters because a squirrel may not enter a new station immediately. It allows time for the animal to encounter the station before the controlled active phase begins.
Visit 2: review and activation
Visit 2 would normally take place around a week later. The technician checks whether the squirrel has used the pre-baited stations.
If the evidence supports continuing, the technician rebaits the stations and activates approved trapping equipment in accordance with the requirements that apply to that trap and the site-specific risk assessment.
If the bait remains untouched, simply activating the equipment because the second visit has arrived may not make sense. Instead, the technician should reconsider the station position, movement route and, where necessary, the original diagnosis.
The office should only schedule activation when the following inspection visits already have protected diary space.
Visit 3: first active inspection
The technician physically inspects every active setup on the following day.
A capture shows that squirrel activity continued during that interval. The technician then reassesses the equipment and surrounding evidence. Where it remains appropriate to continue, the technician can reset the setup if the next required inspection is already secured.
If the traps remain clear, the technician can continue through the next planned active interval where the evidence supports doing so.
Visit 4: clearance assessment
The technician inspects the active setups again on the following day.
If Visits 3 and 4 are both clear and the wider evidence does not suggest continuing activity, the treatment can normally move towards closure.
Where Visit 3 produced a capture but Visit 4 is clear, the clear interval after the latest capture may also support closure. The final assessment should show no other indication of continuing activity.
A capture on Visit 4 changes the decision. The treatment is clearly removing squirrels, but the evidence does not yet support clearance. The programme therefore needs a controlled extension rather than an automatic sign-off.
Our practical clearance rule: every new capture resets the clearance assessment. We do not leave an active setup behind unless the office has already secured the next required inspection. If we cannot guarantee that inspection, we make the equipment incapable of capture until a controlled extension can resume.
How often do squirrel traps need checking?
Once a technician activates a lethal spring trap, the job moves into a more tightly controlled phase. The business can no longer treat the next visit as an ordinary appointment that can move freely around the diary.
Current Forestry Commission guidance on lethal trapping states that traps must be inspected at least once per day by a competent individual who is well trained and experienced. For that reason, our treatment structure uses pre-booked consecutive inspection visits during the active trapping phase.
Electronic monitoring can still provide useful supplementary information. For example, an alert may indicate that equipment has operated before the next scheduled inspection. We do not use electronic monitoring as a substitute for the planned physical inspection of active trapping equipment.
Are squirrel traps legal?
Grey squirrels can be controlled in England, but the method matters. The operator should use equipment approved for the target species and follow the conditions and instructions that apply to that trap.
That means a trap does not become compliant simply because someone places it between two joists. The technician needs to consider the approved trap, its installation requirements, the tunnel or enclosure arrangement, the location and the risk to non-target wildlife together.
If someone catches a grey squirrel alive, they cannot simply take it elsewhere and release it. Grey squirrels are an invasive non-native species, so the law restricts their release.
For customers, there is no need to describe lethal control graphically. Where trapping forms part of how to get rid of squirrels, we can explain that the programme uses approved equipment in an appropriate protected arrangement and manages it through a controlled inspection schedule.
Why the entry point should not simply be blocked immediately
It can be tempting to find the hole and seal it straight away. That approach can create problems if a squirrel remains inside.
A trapped squirrel may search for another route through roof materials, timber, internal finishes or wiring. Dependent young also need consideration because a quiet roof does not automatically prove that an inaccessible nesting area is empty.
The more dependable sequence is usually:
- establish what is using the roof;
- resolve the active occupation;
- obtain evidence that supports closure;
- consider any remaining wildlife implications; and
- complete appropriate proofing.
This does not mean that every property requires trapping before any repair can take place. If the investigation supports that the roof is genuinely unoccupied, exclusion may sometimes be appropriate without a trapping phase.
What about bats in a loft with squirrels?
Bats require a separate assessment rather than treatment as just another non-target animal. British bats and their roosts receive legal protection, so suspected bat activity can change what the pest-control team can do.
A protective tunnel around a squirrel trap does not automatically resolve a bat concern. If evidence suggests that bats use the roof, the trapping or proofing plan may need specialist input before work proceeds.
This is particularly important during proofing. Successful squirrel control does not automatically mean that the team can seal an opening if bats also use that feature.
Two ways to secure a loft against squirrels
Once the evidence supports closure of the active treatment phase and the technician has addressed any protected-species concerns, attention turns to the structural route.
Proofing from outside
External repair can sometimes provide the most direct way to secure a damaged fascia, soffit, eave or other roofline defect.
The team may use suitable mesh, timber repair or another durable physical barrier, depending on the construction. Rotten timber, damaged flashing, broken tiles or broader roof deterioration may require a competent roofer before effective proofing can take place.
Proofing from inside
Some entry routes can be securely addressed from within an accessible loft. This can work well where the internal inspection identifies a clear gap around the eaves.
Internal meshing may also protect a vulnerable section, but the technician needs to understand what space remains accessible beyond that barrier. An internal screen that leaves another connected roof void open may reduce access to one area without solving the wider problem.
Why squirrel problems often return
A squirrel treatment can remove the animal currently using a loft without permanently changing the building.
Recurrence can happen where:
- the original entry point remains open;
- a second route was not identified;
- the roof contains inaccessible connected voids;
- the defect requires proper roofing repair rather than localised pest-proofing;
- proofing is delayed after the active problem has ended; or
- adjoining roofs allow squirrels to move between different parts of the building.
This is why how to get rid of squirrels should not be reduced to trapping alone. Trapping deals with current occupation. Proofing addresses the opportunity for future entry.
Why squirrel treatment sometimes takes longer than expected
Wild animals do not operate to a pest-control appointment calendar. Some squirrels use the same roof repeatedly, while another animal may only enter occasionally.
An intermittent visitor can therefore be surprisingly difficult to intercept. If the squirrel shows little interest in a pre-baited station, the technician may need to reconsider the route rather than simply leave an active trap in the same position for an open-ended period.
Other factors that can extend treatment include:
- several squirrels using the roof;
- continued catches on consecutive inspections;
- an overlooked secondary entry point;
- large or fragmented roof structures;
- converted areas with inaccessible ceiling voids;
- connected neighbouring roof spaces;
- limited access to the affected area; and
- protected-species or structural issues that change what the team can safely do.
If Visits 3 and 4 both produce a capture, the trapping has not failed. The programme is successfully intercepting squirrels, but the latest evidence still shows activity. The technician should therefore extend or reassess the treatment instead of declaring the job complete.
What should you prepare before a squirrel visit?
Most homes require relatively little preparation.
If there is an internal loft hatch:
- clear the floor area immediately beneath it;
- move fragile items that could obstruct ladder positioning;
- make sure the technician can reach the hatch easily; and
- do not enter the loft or interfere with treatment equipment during the programme.
If the team may need external access, make sure relevant gates can open and move vehicles or other obstructions where practical.
For terraced or difficult-access properties, permission from a neighbour may occasionally provide a safer external route for equipment. Arrange this before the visit rather than waiting until the technician arrives.
Are ultrasonic squirrel deterrents enough?
Ultrasonic or electronic deterrents appeal because they appear to offer a non-invasive solution. In practice, they do not repair a roof defect, remove a nest or establish whether squirrels remain inside the building.
An individual animal may initially react to a new stimulus, but homeowners should not rely on this as the main long-term control strategy.
Where a squirrel has established itself in a secure roof space, inspection, appropriate control and permanent repair of the access route provide a more dependable route for how to get rid of squirrels.
Risks of leaving squirrels in the loft
A squirrel in a roof space can create more than a noise problem.
Potential consequences include:
- disturbance and contamination of loft insulation;
- damage to stored material;
- gnawing to timber and building components;
- damage to electrical cable insulation;
- enlargement of vulnerable roof openings; and
- access to poorly covered water-storage tanks in some older properties.
If the technician finds significant electrical damage, an electrician may need to assess the affected circuit. Where structural timber appears seriously damaged, an appropriate building professional should assess it rather than relying on the pest-control inspection alone.
A hidden animal carcass can also create odour and sometimes secondary fly activity. Retrieval depends on whether the affected void can be accessed safely and whether invasive building work would be proportionate.
How to get rid of squirrels and stop them coming back
The most reliable answer to how to get rid of squirrels is not one trap or one repair. It is a sequence of evidence-based decisions.
- Confirm that the evidence is consistent with grey-squirrel activity.
- Inspect the accessible roof and identify likely movement and entry routes.
- Assess risks to non-target and protected wildlife.
- Where trapping is appropriate, pre-bait before activating approved equipment.
- Inspect active equipment through a controlled, pre-booked programme.
- Continue or extend treatment until the evidence supports closure of the active phase.
- Secure the structural route, or refer the relevant defect to a roofer or another competent trade where necessary.
The practical difficulty and cost can vary considerably between an accessible domestic loft and a converted or high-level roof that requires specialist access. Our guide to pest control costs in London explains why access, treatment complexity and follow-up requirements influence pricing.
If you are trying to work out how to get rid of squirrels because you hear daytime movement in the roof, find gnawing or repeatedly see squirrels entering the building, our squirrel control team in London can inspect the problem, assess the access route and recommend an appropriate treatment and proofing plan.
Frequently asked questions about how to get rid of squirrels
Will squirrels eventually leave the loft on their own?
A squirrel may leave the roof to forage, but that does not mean it has abandoned the site. If the loft offers secure shelter and the entry route remains available, activity may continue or return.
How do I know whether the noise is squirrels or mice?
Timing and weight of movement provide useful clues. Squirrels are mainly active during daylight and can produce relatively heavy movement. Mice are much smaller and tend to show more activity at night. Physical evidence in the loft still gives the more reliable diagnosis.
Can I use squirrel traps myself?
Wildlife trapping carries legal and welfare responsibilities. Operators need to use equipment approved for the target species, follow the applicable conditions and protect other wildlife from accidental capture. A live-caught grey squirrel cannot simply be released elsewhere.
Should I block the squirrel entry hole immediately?
Not if there is a reasonable possibility that squirrels or dependent young remain inside. Closing the route too early can trap wildlife within the structure. The evidence should support closure before permanent sealing proceeds.
How long does professional squirrel treatment take?
Our standard programme uses an initial pre-baiting period followed by a short, closely managed active-trapping phase. A straightforward job may move through the planned four visits without extension. Continuing captures or complicated roof access can require additional treatment.
What happens if a squirrel is caught on the final visit?
The capture shows that the treatment is working, but it also shows that squirrel activity continued up to that inspection. The technician should therefore extend or reassess the programme rather than automatically sign the treatment off as clear.
What if I still hear noises after treatment?
Report continuing noise rather than automatically assuming that another squirrel remains. The timing and location can be compared with the inspection findings. In some buildings, mice, rats, birds or activity in connected roof spaces can produce similar complaints.
When can squirrel proofing be carried out?
Proofing can normally proceed when the treatment evidence supports closure of the active squirrel phase and the technician considers permanent closure appropriate. Any suspected bat use or other protected-species issue needs separate consideration before the team seals a roof opening.
