Q&A Home

Dave from Carlisle Pa writes,

Is there some that can be sprayed inside framed walls that would create a long-term barrier?

Building a new home. Wondering if there is something out there that can be sprayed into the enclosed (but not yet insulated or drywalled) home to create a long-term bug barrier. DIY or professional. Thanks for any input.


BoraCare is a wood preservative that can be sprayed directly on the wood studs to kill wood destryoying insects and last indefinately, it never goes away. As far as other general insect pests, a broad spectrum insecticide dust such as Cimexa Dust can be applied inside of the wall void to kill a wide variety of insects. Cimexa Dust will normally last at least 10 years when left undisturbed and can be applied prior to installing sheetrock or drywall or through the openeing of faceplates of electrical outlets and light switches once drywall is installed. Both of these products are designed for long term control. Please be sure to read the product label for complete use instructions.
