What to Do When You See Termite Swarmers in South Jersey
Termite swarmers emerging inside your Philadelphia, PA home are not a minor nuisance — they are proof of an active colony nearby. Here is exactly what to do the moment you spot them.
What Are Termite Swarmers?
Termite swarmers — also called alates — are winged reproductive termites released by mature colonies when population and conditions are right. In Philadelphia, PA and throughout South Jersey, swarm events typically occur on warm, humid days between late March and May, often following a rain event. They emerge in large numbers, shed their wings quickly, and attempt to pair up and establish new colonies.
Finding Swarmers Inside Your Home Means One Thing
If you find swarmers or discarded wings inside your home — on windowsills, near light fixtures, or scattered across floors — a mature termite colony is already present either within or directly adjacent to your structure. Swarmers do not travel far. Indoor swarming is not a warning that termites might arrive; it is evidence they have already been feeding on your home, in many cases for three to five years before swarmers appear.
Swarmers vs. Flying Ants: How to Tell Them Apart
This distinction matters because misidentification leads to wrong treatment. Termite swarmers have:
- Straight, beaded antennae (ants have elbowed antennae)
- Two pairs of wings of equal length (ants have a longer front pair)
- A broad waist with no constriction (ants have a pinched waist)
- Wings that easily detach and are found scattered near the emergence point
If you are unsure, save a few specimens in a small container and have them identified by a professional. The treatment approach differs dramatically between carpenter ants and termites.
What to Do Immediately After Finding Swarmers
Do not spray the swarmers with aerosol. Killing the swarmers does not kill the colony — it simply removes the visible evidence while the primary colony continues feeding. Instead:
- Note the exact location where you found the swarmers or discarded wings
- Save several specimens for identification if possible
- Check nearby wood for soft spots by pressing with a screwdriver — if the wood gives, damage is already present
- Look for mud tubes on nearby foundation walls or framing
- Call a pest control professional for an inspection immediately — not next week
South Jersey Homes at Highest Risk
Philadelphia, PA's sandy soil, high moisture levels near the Cooper River watershed, and aging housing stock in boroughs like Haddonfield, Collingswood, and Audubon create ideal termite conditions. Homes built before the 1970s in these communities were generally not pre-treated during construction and often have never received professional termite treatment at any point in their history.
Treatment Options After a Swarm Event
Termite treatment following confirmed swarmer activity typically involves a liquid soil treatment applied around the full perimeter of the foundation — creating a continuous chemical barrier in the soil that foraging workers contact and carry back to the colony. Bait station systems offer an alternative or supplement for sensitive areas. The choice of method depends on your home's construction type, soil conditions, and the location of termite activity.
If you have found termite swarmers anywhere in your Cherry Hill, Voorhees, Haddonfield, or Collingswood home, call Philadelphia Pest Control Near Me immediately at (555) 555-5555. Termite treatment started the day of a swarm costs far less than the structural repairs that follow months of inaction.
