When we first heard rats in our attic we called Orkin because they are a well known company. We found out that you have to sign up for a 6 month plan where they check out your house each month for $80 a time. I didn't realize that this was automatic. So the guy came by twice, put in glue traps in the attic (which I think he never took out), and closed up a hole into the attic. I think that hole was what worked, because from then on we didn't have rats (for awhile) but he never did catch any. Then for the next 4-5 mos. he would just "stop by" whenever he felt like it for the official monthly checkup, and we would be charged $80. I guess he stopped by and looked outside the house because he never connected with me and I never let him in again. I wouldn't use them for anything large again (they might be okay for just spraying for insects) and probably not at all because of their 6 month system and lack of customer service.
