How long does tent fumigation keep drywood termites away?
Tuesday, November 2, 2021
While tent fumigation is extremely effective at killing all the drywood termites in a house, it leaves behind no residual chemicals to protect the home. Although theoretically they could move back in the day after the tent is removed, the good news is that drywood termites are much slower than subterranean termites to establish a new colony. They only swarm once a year and are weak, short-distance flyers that must also be lucky enough to land near an entry point into the house structure. Then it takes years after that for them to build up enough numbers to do significant damage. An annual inspection by a licensed pest control operator is your best protection against drywood termites going forward.
Fumigation kills pretty much every living thing inside the house, including ants, roaches, rats, and house plants. But it's not effective against subterranean termites. They live in the ground and, although the gas will kill the subterraneans in the house at the time of the tenting, it does not penetrate deep enough into the soil to kill the entire colony.
