Could you identify this small black bug that's in our house?

Clarion County Pennsylvania

Expert Response

It is a species of weevil, but I can't tell you what specific weevil it might be.  There are hundreds of common species.  Only a few are commonly found inside buildings, and two species that look a lot like the one in your photo is the rice weevil and the granary weevil.  Both can infest stored dried food products like rice, beans or whole kernel corn.

Thank you so much for your response.  Maybe came in with some bird food perhaps  We put a fogger off today in our house.  Hoping for luck with that.  Any other suggestions?  Thank you so much!!

If you actually have an infestation inside a package or container of stored dried grains, A a fogger application of an insecticide will not likely get to the insects and kill them.  In fact, you would not want it to, as that would mean insecticide residues in your food.

The only truly effective way to deal with stored product pests is to thoroughly inspect all possible food sources that the insects could use and dispose of any which are infested.
