Arlington Heights is a established northwest Cook County suburb, a mix of 1950s through 1970s ranch homes and newer construction filling in around them. The housing age is moderate, which keeps roach and rodent pressure in the middle of the range, lower than the old inner-ring suburbs but higher than the brand-new outer subdivisions. What stands out in Arlington Heights is the mature tree canopy. The older ranch neighborhoods have had decades for their trees to grow large, and that canopy drives stinging-insect pressure: wasps, hornets, and yellowjackets find plenty of nesting sites in mature trees, shrubs, and the eaves of settled homes. The trees also feed the fall invaders that follow boxelder, ash, and maple. Arlington Heights homeowners deal with a fairly typical northwest-suburban mix, with stinging insects standing out as the pest the tree canopy makes most noticeable.

When to call a Arlington Heights exterminator
In Arlington Heights, stinging insects are the calls that should not wait. The mature tree canopy gives wasps, hornets, and yellowjackets ample nesting sites, and a nest near a door, deck, or play area is worth handling fast, especially in late August and September when colonies peak and turn aggressive. If anyone in the home has a sting allergy, do not approach the nest yourself. Cicada killers, the large solitary wasps that dig burrows in lawns, appear in July and August and look alarming but rarely sting. Carpenter ants are common in the older ranch homes with mature trees nearby; big black ants indoors usually mean a nest in damp framing. Fall invaders push into wall voids in September, so seal the exterior beforehand, and seal rodent entry points before October.
