Over the last few years it certainly hasn’t been cold enough in Arizona to freeze out the bugs. Some insects actually have a type of antifreeze or so called blood within their bodies. They crawl into a nook or hiding spot and if it is cold they just don’t come out. If it warms out they will come out and possible go in search of food.

• If it rains and they get flooded they search for drier land, that might be your house.
• If it is really hot, they might be more active and search for food.
• If its cold for only a few days, that might not be enough to kill them, Especially scorpions or the hardier of the insects.

Filling in those cracks or holes around your home will help to keep them out and also keep the cool or warm in. Caulking is an excellent tool in keeping those bugs out – buy and use the clear caulk. It really works well.
