Why do I see winged ants in my Pittsburgh home in spring?
Winged ants are reproductives that swarm to start new colonies. Penn State says carpenter ants produce 200 to 400 winged ants per colony, and they typically leave the nest in spring. If you see them indoors, it likely means a mature colony is nesting inside your walls or wood. A professional can locate and treat it.

Why do ants come into my house in winter in Pittsburgh?
Some ants, like carpenter ants, can be active indoors during winter if they have a nest inside. With Pittsburgh winter lows averaging 22 degrees, nothing is walking in from the yard in January, so the colony is already inside the building. Seeing ants in winter often indicates an established indoor colony. A professional can inspect and treat the nest, even in cold months.
How do I find the carpenter ant nest in my house?
Carpenter ant nests are often near moisture, such as leaky roofs, windows, or bathrooms. Look for sawdust piles and follow the ants' trails. At night, you might hear faint rustling in walls. If you can't find the nest, a professional can use moisture meters and borescopes to locate it.
Is it legal to spray pesticides myself in Pittsburgh?
You can use over-the-counter pesticides on your own property. However, in Pennsylvania, if you hire someone to apply pesticides, they must be licensed as a commercial applicator or use a registered technician. This ensures they have training. So, if you call a pro, you can expect them to be certified.
What should I do if I see an ant trail in my kitchen?
First, identify the type of ant. If they are small and black, they might be pavement ants or odorous house ants. Wipe up the trail, but don't spray them, as that can scatter the colony. Instead, place bait stations along the trail. If the problem persists, call a professional.
