During the late spring and summer, it is not uncommon to see scorpions in our house. We live in a newer development in the Arizona desert. The older developments do not seem to have as many problems with them.
Steve goes outside after dark with a black light, and kills about 20 every night. There is not much that can be done about them. They live in the block walls of our backyard throughout the neighborhood. Many people spray their house; indoors and out, in hopes to rid their food supply and drive them away. But they still complain that they have them.
Diatomaceous Earth is something that we use. It can be sprinkled around the base of the block walls and around the perimeters of the house. As the scorpion crawls across it, it will cut into him and cause him to dehydrate and die. But they multiply quickly and it is hard to get rid of them all.
During the summer, we kill one in the house about once a week. We shake out our shoes and make sure to be careful when picking any thing up off the floor. The shower floor is another place that we find them.
Steve and I have both been stung multiple times, and I have girl friends who say that they would not live in such a situation. But we all have things that we learn to live with. They really do not bother me as much as I had thought that they would.
