Knew we had carpenter ants but never dreamed there were so many. When the technician said we would see hundreds of ants mostly dead but some alive, I thought oh yeah right. In the next few days we saw 20 to 30 dead ants in the bathrooms, kitchen and living room. And there were a few like they said that were bringing the poison back to the nests. Can't wait to see if they are gone in a month like he said.
