We had a problem with those nasty black ants. I called Ables pest control to my rescue. They were great, They put stuff round and sprayed once the out side of my home. They also put stuff in my garage to get them out side. He also found the nest in the ground and that was it. I use to have them in my mulch. Haven't seen one. Great service. They will come back as many times as you need them. Nice service to serve your needs!
