Calling in an exterminator for a home pest control project is always a rather inconvenient thing. Not only is there a lot of money involved and not only do you have to clear out for a couple of days and find another place to stay, you have to worry also about how safe the exterminator's methods are. They need you to leave your own home for a couple of days because they use of dangerous poisons there. You should always consider how safe a home pest control project is to all involved people, animals and plants. You don't want a situation where the cure is worse than the disease.
The problem isn't an imaginary one. Exterminator companies are required to follow the guidelines of the and PMA and the NPMA that prescribe what pesticides are considered safe for residential areas. For anyone working with poisons, it's always a major concern that the treatments they use shouldn't actually do any harm. Before you actually hire a home pest control service, you need to talk to them about the exact pesticides they use and how there might be better alternatives. Sometimes, you have asked for these things or they will just to assume that you want the cheapest alternative.
The safety argument is actually a very good reason why no one should attempt a full home pest control project on their own, without help from a professional exterminator. The professionals have the training and the licenses needed to know what kind of pesticides are safe and which ones aren't, for home pest control purposes. Back when there was no state licensing in place for home pest control businesses, reports of entire families sickening were routine. It isn't a small matter; families considering home pest control should really make sure they hire professionals, and they should talk to them about the least toxic method possible.
In fact, the latest in home pest control is to use biological agents. Now while the name might sound pretty scary, it isn't really. "Biological agent" is just a fancy name for a new direction in home pest control where they bring in birds, animals and insects that are natural predators of whatever infests your home. It's about the best thing for the environment possible.
If you have bedbugs, then diatomaceous earth is said to be the best natural and green extermination method possible. Diatomaceous earth is a very fine powder. It's a kind of natural calcium sediment, if you will. When you dust your infested area with this fine powder, the powder tends to stick to the bedbugs and it just dries them out. Try to go with an exterminator who uses safe and natural methods like these, and you will certainly come out better for it.
