March through May is Subterranean Termite swarming season. When the temperatures get above 70 and the air has moisture in it from recent rainfall or when we are getting our sprinklers going, these guys build up their mud shelter tubes out of the ground, floor, wall or crack in concrete slab to send hundreds of swarmer’s out to start new colonies elsewhere. I have actually seen this happen 3-4 times out of the blue in the middle of the floor, as the picture shows, a shelter tube for the swarmers to fly out from. One time I saw this right under a recliner chair, I wish we had cell phones like now I would have took a picture of that one. Be on the lookout for these oddities that can appear in just a day or two. You know who to call when or if this happens.
