I've used Horizon Pest Control several times but for I'm not sure about the last time they came, I'm still having an ant issue. I still have ants in the kitchen and I'm not sure how well he did for getting rid of them.
Besides the ants, I'm also having an infestation of little moths so again, I'm not sure about how effective that was.
I've used them for years usually outside and inside hasn't been a problem as far as I know and it was just the kitchen that came up as an issue. I'm still giving them 4 stars because it's likely that they'll come back and take care of this problem.
