Significant rainfall events in St. Louis County produce predictable pest surges. Subterranean termites and carpenter ants are displaced from saturated soil and enter structures at higher rates in the days following heavy rain. Mosquito populations spike 7–14 days after flooding as standing water provides breeding habitat at elevated volumes. Rodents displaced from flooded burrows seek elevated structural access. We recommend inspection scheduling within 2–3 weeks after major flooding events in Affton.

Yes, though car infestations are far less common than home or hotel infestations. Bed bugs are transported into vehicles via infested luggage, clothing, or items placed on infested upholstery. Cars lack the sustained human sleeping proximity that bed bugs require for regular feeding, making vehicle infestations difficult to maintain long-term. However, a car that regularly transports infested items can serve as a secondary harborage and transfer mechanism.

No. Bed bugs infest any environment where people rest long enough to be bitten — hotels, hospitals, movie theaters, office buildings with sleeping accommodations, military barracks, cruise ships, and public transportation. Commercial properties that serve sleeping customers or accommodate overnight stays are at the highest institutional risk. Retail and office environments with no sleep-adjacent seating present lower but not zero risk from infested clothing or belongings brought by employees.

Several factors combine to make bed bug elimination challenging: they are cryptic, hiding in dozens of harborage sites simultaneously; eggs are resistant to most insecticides; populations can survive for months without feeding, outlasting treatment residuals; resistance to pyrethroid insecticides is widespread; and in multi-unit buildings, reinfestation from adjacent units continuously undermines single-unit treatment. Comprehensive, multi-method approaches applied to all harborage sites simultaneously are required for reliable elimination.

The most reliable signs are small dark fecal spots on mattress seams, box springs, and headboards; tiny shed exoskeletons left by nymphs as they grow; and live bugs in the seams and folds of mattresses and upholstered furniture. Bite reactions are unreliable indicators because individual responses vary widely. Finding physical evidence — fecal spotting, shed skins, or live bugs — confirms infestation more reliably than bite patterns alone.

Bed bugs are not found in the outdoor environment — every infestation traces to human activity. They are transported via luggage and personal belongings from infested hotels and accommodations, through secondhand furniture and mattresses from infested sources, in shipments of goods that passed through infested warehouses, and through walls and utility conduit in multi-unit residential buildings. There is no connection between sanitation levels and bed bug introduction.

Bed bugs spread through physical transport of infested items — luggage, furniture, clothing, and packaging. In multi-unit buildings, they spread through shared wall cavities, pipe chases, and conduit runs between adjacent units. They do not fly or jump; all movement is through crawling and passive transport. A single infested room in an apartment building or hotel can be the source of infestations in multiple adjacent units within weeks.

Adult bed bugs are flat, oval-shaped insects approximately 1/4 inch long, mahogany to reddish-brown in color — turning darker red after feeding. Unfed adults are flat enough to hide behind wall plates and in mattress seams. Nymphs are smaller and paler, nearly translucent before their first blood meal. Eggs are white, 1mm long, and deposited in cracks and seams in clusters near harborage sites.

No. Bed bugs infest any location near a human sleeping or resting area. They are commonly found in the seams and frames of upholstered furniture, behind headboards, in electrical outlet covers, behind wall art, in baseboards, inside nightstands, and in carpet tack strips adjacent to sleeping areas. In heavily infested properties, they may spread to multiple rooms and less obvious harborage sites throughout the structure.

Bed bugs are photophobic and retreat to harborage sites after feeding. Primary harborage includes mattress seams, box spring interiors, behind headboards, in the joints of bed frames, and in the folds of upholstered furniture. Secondary harborage extends to electrical outlets, behind switch plates, under carpet edges, in baseboards, behind hanging pictures, and inside books and clutter near the sleeping area.

Yes. Adult bed bugs are visible to the naked eye — approximately the size and shape of an apple seed. Nymphs in early instars are smaller and paler but also visible. Eggs are small and require close inspection. Despite being visible, bed bugs are rarely seen because they are nocturnal, avoid light, and retreat to deep harborage during the day. A professional inspection uses specialized techniques to locate hidden infestations.

Bed bug bites typically appear as small, red, raised welts that itch, often arranged in a linear or clustered pattern because multiple bugs feed from the same area. However, roughly 30 percent of people have no visible reaction to bed bug bites, and reactions in others can range from small marks to large welts. Bites alone are not a reliable confirmation of infestation — physical evidence of the bug itself is required for positive identification.

Bed bug bites do not transmit disease. The primary health concerns are secondary skin infection from scratching, allergic reactions in sensitive individuals, and the psychological and sleep disruption impacts of living with an active infestation. Severe allergic reactions to bed bug bites are rare but documented. The public health impact of bed bugs is primarily quality-of-life rather than direct disease transmission.
