Helping us sleep at night- We formerly had a problem with scorpions, and had other pest control companies tell us that they really could not be completely removed. A neighbor recommended Preventive, and we tried them. I am happy to say that I haven't seen a scorpion in a very long time! Our exterminator is Chad, who listens to your pest problems, and then sets out to get rid of them. He is very thorough and professional. I'm happy.
