When to pick up the phone
Most of Markham's housing stock goes back to the 1940s through 1970s. That older wood framing gives ants a lot more to work with than a newer build would. Watch for these signs.

What the calendar changes
Ant activity around Markham generally stretches from May into August, and carpenter ants tend to swarm earlier, toward late spring. The clay soil common to the Chicago lake plain holds moisture against foundations longer than sandier ground. In practice, that keeps colonies active and feeding closer to the house.

Local conditions that shape the work
Markham's growth mostly happened between the 1940s and the 1970s, and the city hasn't seen much new residential construction since. So what you get is a lot of wood-frame ranch and Cape Cod homes, with brick veneer and original framing that's had decades to absorb moisture and settle. That matters for ants more than people expect. Carpenter ants don't eat wood the way termites do. But they'll tunnel through it once it's gone soft from a slow leak or years of condensation, and older foundations simply give them more soft spots to find.
The clay and silty clay loam soil under most of Markham drains poorly, which is part of why the city leans on engineered stormwater systems instead of natural runoff. In practice that means moisture sits closer to foundations longer after a rain, and that's exactly the condition carpenter ants look for. Add a humid continental climate with hot, sticky summers, and you get a steady window from May through August where ant activity picks up fast. Homes near Hazel Crest, Posen, Harvey or Midlothian see the same pattern, since the soil and housing era hold pretty consistent across this stretch of south Cook County.

Before you call
Are carpenter ants common in Markham homes?
More often than not, yes. So much of Markham's housing dates to the 1940s through 1970s, and that older framing, combined with the area's clay soil and poor drainage, gives carpenter ants more damp wood to target than you'd find in newer construction.
How fast does ant control work in Markham take effect?
Generally a few days to a couple of weeks, depending on colony size. Trail treatments often cut down visible activity within days. A full carpenter ant job, especially one involving wood damage, may need a follow-up visit to confirm the colony's actually gone.
Does ant season in Markham run longer than elsewhere in Cook County?
Not really longer. But the moisture retention from Markham's clay soil can keep ants active closer to foundations throughout the May to August window. That's about all it comes down to: soil and housing age working together.
Should I wait until spring to call about ants?
Seeing sawdust or large black ants near damp wood right now? Don't wait. Carpenter ants can keep tunneling through the colder months indoors, and catching it early generally keeps the repair bill smaller than the pest control bill.
