i live in an old house with some log framing and stone foundation. the basement is a utility basement and has an earth floor. i have always assumed that i had termites here and there but the damage is not obvious if they are in the house. i do have dry rot but have seen no insects. today i found termites 15 yards from the house in an arbevitea (sp) stump. i just happened to pull a piece of bark of the stump and wow, obvious termites. i saw mature bugs and some really small ones. here is what i know... i need to get the earth away from the wood at the seem of the housewhere the house meets the foundation. i need to remove all vegetation that is in contact with that portion of the house as well. i need to end up with ground...bare foundation and then house. what i need to know... what insecticides are used to combat these little buggers? i am no chemical fan by any means but i cannot allow termites to invade my home. are there any natural things i can do to discourage them?
