Most of what people believe about bed bugs is outdated or flat wrong. Here are fifteen facts our Chicago technicians wish more homeowners knew before calling us.
Biology and behavior
- Bed bugs can live 4–6 months — and over a year in cool conditions — without feeding.
- A single female lays 1–5 eggs a day and 200–500 in her lifetime.
- Eggs hatch in 6–10 days and reach adulthood in about 5 weeks.
- Bed bugs go through five nymph stages, molting after each blood meal.
- They detect you primarily by CO₂, body heat, and skin chemistry — not light.
How they spread
- Bed bugs do not fly or jump. They crawl, and they hitchhike.
- They are found in five-star hotels just as often as in low-budget motels — cleanliness is unrelated.
- About 1 in 5 Americans has had a bed bug encounter or knows someone who has.
- Used furniture is one of the most common ways infestations begin.
- They move between apartments through wall voids, outlets, and shared plumbing.
Treatment realities
- Bed bug eggs are glued to surfaces and survive most contact sprays.
- Adults can survive temperatures down to about 0°F but die at sustained 118°F.
- Foggers and bug bombs scatter bed bugs deeper into walls — they don't kill the population.
- Resistance to common pyrethroid insecticides is now widespread across U.S. populations.
- Most successful treatments combine heat or steam with targeted residual products and follow-ups.
What this means for you
Bed bugs are persistent, hard to see, and immune to most consumer products. Catching them early dramatically reduces the cost and length of treatment. If you suspect activity, get a professional inspection before the population establishes.
