How often do Termites swarm?
Termites typically swarm in the spring and the swarm can last from one day, to 3 months depending on how constant your weather is. Termites usually require a warm day to swarm, but your furnace could get them to swarm on cold ones. Sorry there is no “effective” DIY product out there to solve a termite problem, a professional uses a 4 foot rod to inject chemicals into the soil around & under your structure. All DIY products have disclaimers on them telling you to seek a professional, so heed my advice & theirs.
