drywood termites in one of my window frames. Do larger holes need to be drilled or can I apply to existing pinhole
I found drywood termite droppings in one of my window sills. I called in an extermator and the only sign of termites was that one window in my bedroom. Would I need to drill larger holes in the window and then apply the poison or can I apply it to the existing pin holes that were created by the termites? I live in a 1923 house and I don't want to cause more damage to the wood frame. My house was thoroghly inspected but the only activity was in one window. No swarming, no wings, no sign of the culprit, just the droppings that look like coffee grinds in that one window.
You can try using a small syringe and injecting the holes. Basically these holes lead to the colony, so if you are successful in injecting enough chemical in the right place, you can gain control. Its worth a try. Termidor foam is good for this type of treatment too.
