So far so good. I have gone through 4 exterminating companies due to the insane amounts of scorpions I have had (stung 3 times, dog twice). I hated paying my bill because it seemed like nothing was being done. I actually tried Lights out after reading some reviews here and liked the idea of someone checking for them at night and seeing where they may be coming from. He was straight forward and no BS. So far no scorpions in the house. Last year this time i was dancing around them. I like the email reminder that hes going to be out. Keep up the good work
