Insect resistance inside walls

| Posted in Construction Techniques on May 30, 2002 05:34am

I’m getting ready to insulate and drywall the walls.
I’ve been told that I should place diatomaceous clay and borax powder
on the sill plates to discourage the movement of ants, etc. Apparently they don’t like crossing the material.

What would most people recommend for non-toxic preventive measures?

Thanks,

Steve

    Steve,

    Insulate with cels and bug problem is fixed or use a boric acid spray that is available from pest control companies.

      Hi KK,

      I think I can probably find the boric acid spray, but I'm not acquainted with "cels". Is that the sprayed in cellulose?

      Thanks,

      Steve

        cells is cellulose...which contains boric acid as it's fireproofing..

        Bora-care is the trade name of the spray..

        don't know much about sorces for diatomaceous earth... but the Bora-care & cellulose should do the trick... that and making sure you don't have a moisture problem.....Mike Smith   Rhode Island : Design / Build / Repair / Restore

          I'll probably go with the fiberglass batts. Would I use the boric spray

          on the stud cavities prior to laying the batts?

          Thanks for you help,

          Steve

            Try diatomaceous earth. Available in large sacks at reasonable prices from a pool supply company. It is chemically inert and nontoxic. It is so fine and abrasive that it is said to get into the leg joins of insects where it chews up the seals between the leg sections causing the critter to bleed to death.

            The boric acid suggested needs to be baited with an attractant so the insects eat it or be so fine and loose that it is picked up on their legs and ingested when they clean themselves. The problem being that boric acid, especially in humid areas, tends to cake.

            There are many sites touting diatomaceous earth or a proprietary variation for insect control. Here's one.

            http://www.diatomaceousearth.co.uk/

            A Google search will provide several thousand links and hours of reading.

            I like this link better.

            DE for pools and gardens are different things. Boric acid spray (Permadust) does not need to be baited. It is an aeresol that is sticky and used by pest control companies in food safe areas.

    A few years ago I had a DE pool filter and if I recall correctly there were warning notices on the bags about not breating the dust because it was so fine and abrasive. If it can get into the joints of insect apendages think how far it can get into your lungs.

    Think about asbestos

    Think about the next guy that works on your house.

    It's O.k. to think out of the box,           Just don't walk off of the plank!

    Roach Prufe http://www.copperbrite.com/roach.html is pretty effective ........... spinkle some in the bays before you insulate.
