Moved to Gilbert 12/19 (from out of state) and unfortunately into a vacant home that ended up having a significant scorpion issue. Hired a different pest company first and after finding the first scorpion stuck to a glue trap in my garage, I bought a black light flashlight and some Terro and to my horror was killing at least a dozen scorpions outside nightly... In the Winter! After a few months of no changes with said previous company, I was referred to Responsible. I concluded a significant amount of scorpions were coming out of my attic and from two neighbors yards (and in the block walls). Responsible treated my attic and that 100% eliminated the issue there (have never found another scorpion coming out of the (screened) vent holes since), and they provide me monthly service outside and occasionally inside. I have also become a bit obsessed with trying to eliminate these critters. I bought a stronger flashlight and visited my local Weed and Bug Mart (see Mike in Gilbert, he is awesome) and also use delta guard and Cy Kick to treat my yards and such. I hunt scorpions every single night about 2-4x nightly after dark, and the combination of all of these tactics has GREATLY reduced, but not eliminated my problem. I have gone as long as almost three weeks during the Summer without finding one scorpion, but it seems to go in spurts (have found seven in the last three days) and was hoping to be done with these creepy bugs. So far, we have only found three in our house since moving in, and cannot figure out how they are getting in (we have glue traps everywhere, and we screened all of our vents). All told, I couldn't tell you what specifically is reducing the numbers, but saw the most drastic drop when the attic was treated (around April-ish I think) and caulking the block walls. I just think this house and property has been infested for so long, it would take years to come close to elimination (in addition to my neighbors seemingly not caring about scorpions). I don't plan on staying here long enough to find out (we are leasing). Just would hate to go through all of this just to end up in another infested house / yard and having to start over. This is the kind of thing that could make us move out of the Phoenix area for good. All in all, I Like Responsible Pest control, their customer service and they really do listen and react to what I am working on. My tech Ricky is a great guy and will attack anything I need him to - keeping in mind they true trick is killing their food source. Super jealous when I talk to people who have lived here for decades and say they have never seen a scorpion - just come over to my house... I'll show you plenty. Some of my kills below - a lot of babies since September started.
