The optimal window for rodent exclusion in Riverwoods is August through October — before temperatures drop and rodents begin actively seeking entry into heated structures. Mice can enter through gaps as small as a dime; rats through a quarter-sized opening. Once rodents establish inside a structure, both population removal and structural exclusion are required. Exclusion before the search begins is significantly simpler and less expensive than addressing an established infestation after winter entry.

A termite swarm consists of winged reproductives — alates — emerging from a colony to find mates and establish new colonies. They appear as clouds of flying insects near windows, doors, or light sources, often following rain and warmth. Termite alates have equal-length wings that extend past their bodies and straight antennae, distinguishing them from flying ants, which have pinched waists and bent antennae.

No. Both are winged reproductives that swarm seasonally, but termite alates have straight antennae, equal-length wings, and no pinched waist. Flying ants have bent antennae, wings of unequal length with the front pair longer than the rear, and a distinctly pinched waist between the thorax and abdomen. Misidentification leads to the wrong treatment approach.

Subterranean termite colonies nest underground, often several feet below the foundation, making the colony itself inaccessible for direct inspection. Colony presence is inferred from evidence — mud tubes, damaged wood, swarmers, and monitoring station activity. Professional termite inspections identify all active indicators and likely entry points without requiring colony excavation.

A termite inspection is a systematic assessment of a structure for evidence of termite activity and conditions conducive to infestation. Inspectors examine the foundation perimeter for mud tubes, probe accessible wood for damage, assess crawl space conditions, and identify structural vulnerabilities like soil-to-wood contact and moisture intrusion. Written inspection reports document findings and recommended treatment.

Annual termite inspections are appropriate for most homes in moderate-to-high termite pressure zones. Homes in high-activity areas — particularly in the Southeast, Gulf Coast, and warm coastal markets — or homes with known previous activity benefit from inspections every year without exception. Homes under active termite treatment or monitoring contracts receive ongoing assessment as part of those programs.

Termites can reinfest a structure if the protective treatment zone breaks down or if new termite populations establish in previously untreated soil areas. Liquid termiticide barriers have a finite effective life in the soil. Regular professional inspections detect early evidence of reinfestation before populations establish and damage accumulates.

Yes. Subterranean termites continue foraging and consuming wood year-round in climates where soil temperatures remain above approximately 50°F. In colder climates, colonies retreat deeper into the soil during winter but resume foraging immediately when temperatures warm. Structural damage accumulates continuously during all periods of colony activity.

Subterranean termite damage appears as wood that sounds hollow when tapped, galleries running along the grain, and framing that collapses under minor pressure. Floors may feel soft or spongy. Drywood termite damage shows as smooth galleries cutting across the wood grain, with frass pellets accumulating below infested wood. Paint bubbling over wood surfaces can indicate moisture from termite activity within the wall cavity.

Termites cannot consume concrete or brick but can exploit cracks in foundation concrete, mortar joints, and gaps around utility penetrations to access wood framing above. Control joints, expansion joints, and settlement cracks that develop over time in any concrete foundation create pathways that termites locate during foraging. Treatment injected through concrete targets these access points.

Pine, fir, and other softwoods used in standard residential framing are more vulnerable than hardwoods. Any wood with elevated moisture content — from plumbing leaks, condensation, or poor drainage — becomes a priority target because moisture softens wood fibers and makes them easier to consume. Older construction using untreated framing lumber close to soil grade is particularly at risk.

Homes in Riverwoods carry termite risk levels that reflect local soil conditions, climate, and the regional termite species active in Illinois. Most U.S. residential property has some degree of termite risk — 49 of 50 states have economically significant termite populations. Understanding your specific risk level requires a professional inspection of the property, not just the ZIP code.
