We have used Orange for a few months now. They guarantee their work, and between treatments in our backyard we started finding quite a few scorpions and called them back out. They were here the next day and treated our whole house including our yard/fence. Since then we have found no scorpions which is a drastic change from a few weeks ago. These guys do a great job and guarantee their work which is hard to come by these days. I'd recommend Orange pest control to anyone.
