I've used Hart Pest Control for 5 years now. My technician is friendly, helpful, honest, and has been on time for every appointment. We prefer a more natural, eco-friendly spray for our home and yard, and Hart has provided that. It works just as well as the regular spray. We have never had to call them back to retreat our home, but it is great to know they will come if I need them. I highly recommend this company!..
