[Shop-talk] Spiders!

[Jack Brooks]

I've had good success with killing crawling things using "Bayer Polyzone Suspend".  It leaves a "film"? that stays active for months, inside and outside that bugs pick up when they move through it.

I spray three buildings 2-3 times a year and manage to keep most of the critters from taking over.  You could spray the outside foundations and inside too in the traffic areas.  Another key is making sure no plants provide a bridge to the house too, so they have to crawl through the Polyzone barrier.

Wear a mask for application, but once dry, 30 minutes or so, it's safe in inhabited areas.

It isn't completely finished so there are probably a few small holes where things can crawl under the siding, through the wall and into the basement. I certainly expect a few spiders but this is ridiculous. They are all the same 2 types - a very tiny gray one and a 1.5" gray one. I thought they might be reproducing faster than I could vacuum them but I read it takes a year for them to hit reproductive age.

Could I still be dealing with his infestation or are they coming from somewhere else? Most importantly how do I stop them? I almost can't have people over. They are in every corner of every room. I'd rather implent physical measures than chemical.
