Seeing winged insects around your home—especially in spring—can be more than just a seasonal nuisance. Termite swarmers (also called alates) are reproductive termites that leave an established colony to start new ones. A few swarmers may not seem like a big deal, but they can be a major warning sign that termites are nearby—or already in your structure.
Here are the top termite swarmer red flags A Plus Pest Control wants homeowners to know.
1) Piles of Discarded Wings
Swarmers don’t keep their wings for long. After they land, they often break off and shed their wings, leaving small piles behind.
Common places to spot wings:
- Window sills and sliding door tracks
- Near light fixtures or lamps
- Along baseboards
- In spider webs (wings get caught easily)
If you’re finding wings indoors, it’s time to take it seriously.
2) Swarmers Appearing Indoors (Not Just Outside)
Termite swarmers are attracted to light, so you may notice them at windows or around lights. A few outside near a porch light can happen—but swarmers inside the home can indicate termites are emerging from within, or entering through an easy pathway.
Red flag level: High.
3) “Flying Ants”… But They Don’t Look Like Ants
Many people assume swarmers are flying ants. There are key differences:
- Termites: straight antennae, thick waist, and four equal-length wings
- Flying ants: elbowed antennae, pinched waist, and uneven wing sizes
If you’re unsure, save a few specimens (or take a clear photo). Correct identification matters.
4) Swarm Activity After Warm Rain or Sudden Warm-Ups
In many areas, termite swarms often happen after rainy periods followed by warm, humid days. If you notice swarming around your property during that kind of weather pattern, it may be part of a local swarm event—but it still means termites are active in the area.
5) Mud Tubes or “Dirt Tunnels” Along the Foundation
Subterranean termites commonly build mud tubes to travel between the soil and wood while staying protected from drying out.
Check:
- Foundation walls
- Crawlspaces
- Garage edges and expansion joints
- Around plumbing penetrations
Mud tubes + swarmers is a combination you don’t want to ignore.
6) Bubbling Paint, Soft Drywall, or Hollow-Sounding Wood
Termites can cause damage that looks like moisture issues. If you tap wood trim and it sounds hollow—or you see blistered paint or warping—that can be consistent with termite activity.
What to Do If You See These Signs
- Don’t spray and forget. Killing visible swarmers doesn’t address the colony.
- Avoid disturbing mud tubes until a pro has assessed them (it can make evidence harder to evaluate).
- Schedule an inspection so the source can be identified and a treatment plan recommended.
If you’re seeing swarmers, wings, or any of the signs above, A Plus Pest Control can help you confirm what’s going on and protect your home before costly damage occurs.
