I have Advanitix and I love it. My house used to be full of spiders (and I mean full, hobos mostly). I used to find at least 1 large spider a day chillin' in my bathtub, not to mention the ones I'd see throughout the rest of the house. Enter Advantix: It's been about 8 months since I started with them and my inside spider count has been maybe 3, and that's without having the inside of the house serviced yet. I know having the inside done would probably take that count down to zero but it's hard to be home for an inside service. My favorite part it going out on my front step and seeing a few dozen insects dead, even in the winter! I read a previous review and was surprised that they had such a bad experience. My recommendation: read the contract and pay attention to what they tell you!!! You know what assuming does.
Pros: They control pests, just like they said they would :)
Cons: I have to sweep a lot of dead insects off my porch...
