Last Friday was sitting at my kitchen table and saw a bunch of bugs swarming around my deck and on my screen door. Took a close look at them and pretty sure they were termites. There were hundreds of dead ones on my deck outside my door. The swarm was gone around a half hour later. I've never seen any evidence of termites around my house, what's the chances that swarm was setting up shop and starting a new colony in my house? Still don't see any evidence around the house, but not sure how long it takes to start seeing it.
