Spring Carpenter Ant Outbreaks: How to Identify Swarmers vs. Termites in Southern Ontario

## The Spring Swarm: Carpenter Ants vs. Subterranean Termites

When warm spring rains arrive in Southern Ontario, winged insects often emerge near window sills and basement foundations. Homeowners frequently panic, asking: *Are these carpenter ants or termites?*

### Quick Identification Chart

### Why Carpenter Ants Target GTA Foundations

Carpenter ants do not eat wood for nutrition; instead, they hollow out damp, decayed lumber to expand their nesting galleries. Common risk factors include leaking gutters, rotting deck posts, or wood firewood stacked directly against house siding.

### Professional IPM Solution

Our non-repellent baiting strategies allow worker ants to forage the bait matrix and carry it back to the parent colony hidden outdoors or inside structural framing, eliminating the queen and stopping destruction at the source.
