I used East Coast Pest this spring for a black ant problem. He seemed very knowledgeable. It's now August and since May have not seen 1 black ant near my backstairs, side walk or patio. Every year I fight with the ants and when have used other companies I've had them back 2 or 3 times that same season. East Coast checked my trees even and found nests there too. Anyway I am thrilled this is the 1st year I haven't seen an ant in any of the usual places since finding East Coast Pest Control. They do a great job!
