Every state has an issue with insects and infestations. What is Wyoming's most annoying one? The one that is most likely seen the most and can be a nuisance.

The weather will begin to get colder but even with the nice weather, if you have a basement some insects flee to those areas and can be worse in the summer even.

Although this data was taken from winter it shows what each state deals with as far as insect infestations. It looks like us along with our neighbors deal with the same insect a lot more then others. For Wyoming that insect is the spider. Spiders were the most common, followed by mosquito then cockroaches.
