I just bought a house that has been vacant for 10 months & spiders have taken up residence in there. Years & years ago I used to buy some things called Bug Bombs that you closed the home up tight & set them off & came back the next day & there were dead bugs everywhere. Then do it again in a couple weeks after any previously laid eggs hatched & you were good to go forever. Do they still make these things or something similar. I don't know where I bought them as it has been a long time since I have used them. Or is there something I could fog the home with. I will be painting all the rooms over the next couple weeks & then cleaning the carpets after that.
