They're not that bad to use, Leon. I have to do my whole house at least once every summer. Just shut off the breaker and the gas line, and leave the house for a couple hours.
Come back... Dead bugs. Except slugs (which aren't bugs, either). Those things seem to be immune to everything that's not salt or sunlight.
Well there's also the problem that it's my parents house, not mine, and they wouldn't be on board with the whole "gas the kitchen" idea. :x
Should only have to deal with this kind of thing for a couple more weeks anyway; winter weather will kill them all off. The recent shift in weather is the entire reason for the sudden influx of spiders in the house, after all. This guy's like the 5th big one in the last couple of weeks. First to get away alive... the ***.
It just wants to cuddle Leon.
It can go cuddle outside in the freezing rain with all the other spiders, then! D:
