we get some ants big ones in the summer and tiny little ones in the fall, this time of year we have alot of the fake ladybug things. surprisingly we don't have any spiders (i think they stay in the basement). We've got stink bugs in the house this year for the first time.
I'd freak if i found a centipede or millipede in the house.
DH sprays when the ants start getting too bad, and we've had some flea issues this year as well - so i think that spray may have helped keep some of the rest of the critters at bay.
