I want to set one off in my garage as it would be a quick way to kill any bugs I may have in there (mostly spiders) and since it's enclosed from living space, even if it's toxic it should be rather safe as long as I vent it off properly afterwards.
I was thinking javex and windex, and a fan, and immediately leave the area once they mix, but not sure how effective that would be. There's still the danger of having to go inside afterwards to remove it.
I'd also like to set one off in the crawlspace under the garage, but since that is open to the house, I'd have to use something that is safe for me and my cat, as it may come upstairs. Though I could always just seran wrap the hole after applying the bomb.
