Ty and Josh really want to get the job done right. I have used Holistic Pet Solutions for a couple of years to deal with carpenter bees, and both times they have come out a second time at no charge to deal with some "leftovers". This year it was ants, and it looks like the treatment has been very effective. While dealing with these unwelcome pests will need to be an annual affair, I'm pleased that the products they use are as non-toxic as possible and are effective. They are great to work with and want to be sure your home is taken care of.
