Yes, house was vacated. I don't know if getting out was necessary or not, but better safe than sorry. I'd think that one could find a day that you're going to be away, maybe even an overnight stay somewhere, & use the bomb(s).

I don't know about bats. I don't know if it's potent enough for mammals that size. I also forgot to look at the product name today on the can. I promise I'll do it tomorrow.

Once again-I'd call the eradication program a 100% success once I found the crawlspace as being the habitat.
