Inoculand offers a Biscuit beetle treatment from £89+vat to treat a kitchen as a one off visit.
Biscuit beetle infestations are mostly linked to our dry food storage and will often infest packaging of flour, biscuits, cereals, spices and other power food stuff. They are dark reddish/brown and very small (3mm long) and could be confused with Furniture beetle.
The Biscuit beetle can bore through paper packaging and even foil and will spread easily.
The eggs will hatch after 2 weeks and the resulting larvae will feed for about 2 months before pupating in cocoons, often inside the food stuff itself. After a further 2 weeks the adults Biscuit beetles will finally emerge ready to repeat the cycle.
The adult Biscuit beetle will hence create an exit hole that looks like woodworm and will move away from the food source eventually flying off. The adults that do not eat, will survive 3-4 weeks during which time they will mate and lay more eggs.
It is quite common to find Biscuit beetles on the window sill of a nearby room as they are trying to follow the light. But the right course of action is tracing them back to where they are originating from.
How to get rid of Biscuit beetles
The first thing is to check the cupboards where you keep your dry food. You may see a few live or dead adults at the bottom or on the shelves of the units that would be a strong indication that one of the food packaging is infested.
Old food packaging are more likely to be infested and should be checked thoroughly. If you are in doubt about a certain item, it may be best to either place it in a sealed container or dispose of it.
Once the dry food cupboards are emptied out and clean, we would then spray the hard surfaces thoroughly with a specially design residual insecticides.
Where are the Biscuit beetles coming from?
Biscuit beetles are sometime linked to nearby bird nests and they can then find their way in crawling through tiny gaps or flying through the window.
But they are more likely to be introduced with our shopping especially from shops with very little shelf turn over.
Other names used to refer to biscuit beetles
Many clients describe them to us as black beetle. Of course black beetles in house is far from being a scientific denomination.
Their Latin name is Stegobium paniceum and they are also commonly known as drugstore beetles and bread beetles.
How can I prevent a Biscuit beetle infestation?
As we mention before, having a good turn-over routine of your dry food stuff and use by date will probably ensure that you will not suffer an extended problem if any at all.
As you buy vulnerable food stuff, do check the integrity of the packaging. Otherwise the best strategy is to keep your dry food stuff in hermetic containers.
