Just bought a place and finding little piles of sawdust in many of the cabinets. However none in door frames, beds or other furniture. The house is concrete. I know there is a product that can be painted on but unsure of name or where to find. Suggestions?

I've actually used Shelltox effectively on smallish areas where they were making trouble.
Timbor is another effective product.

Thanks for the info. Will see what I find 😊

We inject lorsban in to the holes with a syringe.

Solignum works very well. Just apply with a brush and air out the place afterwards as the odor is very strong. Most hardware stores carry the product.

Thanks found some and will starting that project. 😜
