I had a customer ask a question today about pine needles. I guess I never thought about this one. The question was, "Do Pine needles become infested with ticks or fleas? Can my dog use them as a bed without getting ticks or fleas and if so can the needles be treated with flea an tick spray or powders to keep them out?" I just stood there like a dummy and stared! Can anyone shed some light on this subject? Thanks!
