Sparrow pest control has been out to my place 3 different times within the last approximately month and a half. They sprayed for wasps and ants. The 2nd time they supposedly sprayed for spiders and once again, ants. Within a couple of days after the 2nd visit, I had ants in my kitchen. The guy that came out the first time was the same one that came out the 3rd time. Since I know that the ants are coming from the attic and not from below because there's a concrete foundation. All he did was set out 2 ant baits, one was under the fridge, even though I had shown him twice where the ants were coming from. He also sprayed on the lower part of the inside of the front door, since ants were coming in from there as well. I asked him why the inside of the door rather than the outside of the door. He said that spaying the inside of the door was more effective than spraying the outside of the door. Really!? Then using the very same product as they do on the outside as he did on the inside of my door, then what's the use of using it on the outside of the house? It's the same product!!! So then why would the same product be more effective inside!?!? That makes no sense. And when I asked him to inspect the attic, he said that it wasn't necessary. He wouldn't even poke his head up in the attic with a flashlight. And, they NEVER did an initial inspection to see where the ants were coming from!! You need to find their nest !!! All they did was spay a few areas around my place. The 1st guy just doesn't seem very competent, just not very knowledgeable. I've done a great deal of research about these particular ants, and I honestly think that I know a lot more than the guy from Sparrow that came out the 1st and 3rd time. Even though the property owner is using this company, they will NEVER be allowed in the back yard, the front yard or inside my place ever again!! If I have to pay out of my own pocket, I'm going to hire a competent company who will do a through inspection and get rid of the ants, rather than just keep coming out and spaying as often as Sparrow has done. They don't even deserve one star!!
