It’s true that you can go to the store or search online and buy products to control almost every kind of pest, but just because a product is available doesn’t mean that it’s safe or that it’s going to work. Before treating, you have to know what kind of pest you’re dealing with, the extent of the infestation, and how to properly use/apply the product. Even if you only see pests in one area, chances are there are more where you can’t see them. You may also be dealing with more than one type of pest, so getting rid of one will only solve part of the problem.
The most dangerous thing you could possibly do is ignore the products that are available and try to make your own pest control remedy. Off-label mixtures will contain unknown levels of chemicals that can be much higher than those you would buy. These chemicals can react and contaminate your home, endangering you and your family. With DIY methods, pets and children are at an even higher risk of illness from chemical exposure.
Even organic or EPA approved pest control products can cause problems if not applied correctly. Using too much of a chemical can pose a health hazard, while not using enough won’t get rid of the pests. Plus, as you’re trying to hunt down the best place to apply the chemicals, you run the risk of being bitten or attacked by the very same pests you’re trying to eliminate.
