What to expect from our treatment

  • Target the Source
    First we identify and target the source of your pest problem with our custom treatment.
  • Inside Treatment
    We then treat unfinished basements, garages, crawl spaces, trash areas, attics; wherever there is the possibility for a pest to enter your home or make residence, we will create a barrier to protect you. We deploy a variety of techniques depending on what works best for your situation.
  • Outside Treatment
    We create a protective barrier around your home using a granular base around the foundation. We then treat windows and doors, as well as under siding, to keep the pests out. We will also place a granular bait in your flower and mulch beds so that it is taken back to any potential nests, destroying them.

Reviews

Owning a home for the first time is quite stressful, especially with ant hills around. The situation is even worse because of our daughter and her puppy. So pleased that our neighbor recommended the company because the technician convinced us that we don't have to worry because they will take care of our predicament, and really he did. I commend the flexibility!
