I do not like bugs in the house. Years ago, I had a roomate who introduced me to what is still my favorite spider killing technique (only now I have Mr. Doxie for removal of spider corpses ). Bust out the hairspray ladies! One quick spritz of the hairspray will stick that spider down and kill it!
Ants are another peeve and my MIL told me to keep a spray bottle with equal parts water and lemon juice in it and spray the little suckers with it. That works great too. It kills them almost instantly and they do NOT come back for awhile. My neighbor swears by Windex (or anything with ammonia in it) to kill ants, but the lemon/water mixture smells a lot better.
