I live in a 20 year old house in central Maryland. Every year we get invaded by small black (odorous?) house ants in the same locations: under the front door, under the patio door, from the back of the kitchen counter, from the trim under a window. There seem to be more than ever this year. I opened my mailbox the other day and found it full of these ants and their eggs....right where the mail had been sitting a few hours earlier!! I know they are just a nuisance, but I'd like to be rid of them. This year I've seen a trail of large black (carpenter?) ants making it's way up the driveway and front stairs to cracks in the brick and an opening in the wood trim around my front door. These ants sometimes have a greyish abdomen.
1. Why do there seem to be more ants everywhere (indoor and outdoor) this year? We had a ton of rain this spring, btw.
2. I've been using Terro boric acid based syrup as a bait for the little black ants. They love the stuff and after a few days they dissappear, but they come back in a few weeks and always again every year. Does that stuff kill the colony? Are these new colonies that return? Are there any other baits that work that I can find in a hardware store?
3. Should I worry about the carpenter ants coming into the house? I've seen 2 large winged ants (not termites), one inside and one outside right in this area of the house. Since I know where the path they take is(but have not found a colony), is there something I can use there that will destroy the colony?
BTW, I'd rather not do a whole house termidor treatment and I always prefer to use the least toxic method of pest control.
Thanks for this great service!
