Termite Swarms in School Buildings

It’s that time of year again – time for termite swarmers to start showing up. You may have already experienced some swarms in some of your buildings. Eastern subterranean termites generally swarm from late-February to May. Swarming usually occurs during the day, particularly on warm days following rain. Swarmers found outdoors near tree stumps, landscape timbers, etc., are not an indication that a structure is infested, but they serve as a reminder that termites live around us. When swarming occurs indoors, it usually means that there is an infestation somewhere in the building.

If you have indoor swarmers, just suck them up in a vacuum cleaner. Place the vacuum bag inside a plastic bag and seal it before disposing of it. There is no real need to spray them, and spraying would require notification. There is also no need to rush treating the building. This situation would not be considered an emergency. Plan the treatment for a teacher workday where that part of the building is or can be vacated. The treatment will vary depending on where the termites were found swarming. A spot treatment may be all that is needed and will not be as expensive as a full treatment of the structure.
