Can't see that well but ant bodies are segmented around where a waist
might be whereas termites have like a straight waist.

Termites are hard to exterminate yourself if in the house as insecticide
needs to terminate wood.

Bayer makes a couple of treatments to protect the house. One you
sprinkle and water in and is good for about 6 months and another that
requires slight trenching but lasts 2-3 years. I'm assuming
subterranean termites.
