I was having a problem with carpenter ants in my home last year, but this year (2018) they seemed to return with gusto. I looked at the list of options on line and gave Spectrum Pest Control a call. They came out when it fit my schedule, the young man was very knowledgeable, explained what he was going to do, gave suggestions as to what to do with a wet area in the basement, and sprayed all the problem areas in a very timely manner. I am happy to say in the three weeks since our treatment we have only seen three ants and I couldn't be happier. Thank you.
