Fleas are tiny blood-feeding parasites that infest Chicago homes — usually brought in by dogs, cats, or even visiting wildlife. A single female lays up to 50 eggs per day, so an infestation that starts on one pet can spread to every carpet and rug in days.
What Do Fleas Look Like?
Adult fleas are tiny — 1–3 mm long — dark reddish-brown, wingless, with flat bodies and powerful back legs that let them jump 7 inches vertically. They're laterally compressed (thin from side to side) so they slip easily through pet fur.
Where Do Fleas Hide?
Fleas live on the host animal but eggs and larvae develop in the environment — deep in carpet fibers, between hardwood floorboards, in pet bedding, along baseboards, and on upholstered furniture. In Chicago basements they can also live in finished playrooms and under furniture.
Signs of a Flea Infestation
Pets scratching constantly, tiny dark insects jumping on pant legs and ankles, red itchy bites in clusters around ankles and lower legs, and 'flea dirt' (dark specks that turn red when wet) in pet fur and bedding.
Health Risks of Fleas
Fleas can transmit tapeworms to pets and rarely to humans, and severe infestations cause anemia in small animals. Bites cause intense itching and allergic reactions in many people, and secondary infections from scratching are common in children.
How Sleep Tight Treats Fleas in Chicago
Sleep Tight treats fleas with an indoor growth-regulator and adulticide combination that kills active adults and prevents eggs and larvae from developing. The pet must be treated by a vet at the same time, and we'll walk you through vacuuming, washing, and prep so the treatment sticks.

Frequently Asked Questions
How did fleas get into my home if my pet has flea medication?
Even pets on flea medication can bring eggs in from grass, walks, or other animals — the medication kills adult fleas but the home itself can still become infested.
Can fleas live without a pet?
Flea eggs and pupae can survive in carpets for several months waiting for a host. This is why Chicago apartments that sat empty after a previous flea-infested pet often have a sudden flea problem when new residents move in.
Are flea bombs effective?
No — flea foggers don't penetrate carpet fibers where larvae develop and they don't include growth regulators. They give homeowners a false sense of progress.
How long until fleas are gone?
Most Sleep Tight flea treatments resolve in 2–3 weeks, with one follow-up visit to catch newly hatched fleas.
