If termites are blind and shun light just how do they find their way into your home? I mean they live under ground and can’t follow already made pathways but actually have to make tunnels in which to move. Soil particle by soil particle they span out and as if by random and they still find wood to eat. Wood has no odor that attracts them (termites don’t have a nose either) but still homes across America get infested with termites every year to the tune of billions of dollars in treatment and repair costs. There is some research going on right now that suggests termite foraging is not so random and is in fact quite deliberate. While that has yet to come to a full conclusion I can tell you that there are three main reasons that termites will latch onto a structure and blindly or not they’ll search out and eat every fiber of wood they can get their teeth into.
