I have to ask, is this your decision to get the place fumigated, and if so, why? Do you have a pest problem? Personally I don't believe in exterminators... A lot of household pests can be dealt with, without pesticides... some obviously can't... Like if I had termites, spray away... Where I live, at least this neighborhood, everyone seems to have terminex come out several times a year to check and spray... I think it's a complete waste of time... Of course the way people do things around here is like asking for termites... houses low to the ground with not much for a foundation... Then a lot of houses that have crawl space have a board blocking the hole that goes under the house... hello... wood touching the ground and touching your house... I don't get it... All I know is the apartment i'm in I have no choice when they spray the outside.. maybe it's for termites but I see no change in the amount of insects in the apartment before or after the spraying... occasionally I will see more after the spraying, but never less... One time they came in and HAD to put a trap under the bed in the bedroom... They wanted it in one place so they could see where bugs were coming in... What a joke. I went to the hardware store, got my own traps, and caught more bugs than their trap did. Not only that but how could a trap help them locate where bugs come in? I could tell them right away... like hey, look at the door, do you see the light coming in when the door is closed... I've had scorpions in here, bugs of all sizes, spiders, once found a toad, and once a tree frog... where did they come from? Well, personally I HATE chemicals and avoid them when I can. If you have a choice, unless you have bugs already or are extremely at risk, I say avoid it all together. If anyone ever has a problem with fleas, regular ants, cocroaches, spiders, fruit flies, silverfish, firebrats, moths, and probably a few other bugs, I can dig up some helpful hints that should allow you to avoid pesticides... If you have termites, carpenter ants, or a severe infestation of something, then there are less options... Man I hate chemicals... You know they don't just evaporate into thin air... but we just keep dumping them and dumping them all over the place........ Okay... I need to breathe..... sorry for ranting so much...
