Roberta from Ontario, Ca writes,
Which drill bit should I order for treating subterranean termites?
Do you recommend the 18" or the 24" drill bit when treating for subterranean termite?
You mentioned earlier that the 18" bit wasn't long enough for you because the shank was included in the 18". If this is the case you should consider using the 24" bit to get through the concrete.
