Termites

Do termite swarms mean the house is infested?

A swarm inside a living room, with wings on a windowsill, is a strong sign that Subterranean termite or Drywood termite are using the building. Outdoor evening swarms in spring can come from a neighbor’s yard or a stump. Still walk the foundation for tubes. Ant swarms have elbowed antennae and pinched waists — see the comparison guide.

Do not spray the swarmers as the treatment

Killing alates does not kill the colony. Vacuum the wings for ID, then hire inspection. A hardware-aisle can is not a termite bond.
