Bed Bugs

Do NOT use bug bombs or foggers — they scatter bed bugs to new rooms and make the problem worse. Call a professional.
Bed bugs have made a dramatic resurgence across the United States over the past two decades, affecting every type of dwelling from budget motels to luxury apartments. These small, flat, reddish-brown insects feed exclusively on blood — primarily human — and are most active between 2 AM and 5 AM while their hosts sleep.
Adult bed bugs are about the size of an apple seed (4-5mm) and can be seen with the naked eye. They are expert hitchhikers, spreading through luggage, clothing, used furniture, and even office buildings. Bed bugs have nothing to do with cleanliness — they have been found in five-star hotels, hospitals, movie theaters, and public transit.
A single female bed bug can lay 200-500 eggs in her lifetime, and eggs hatch in 6-10 days. This means a small introduction can become a serious infestation within weeks. Bed bugs can survive up to a year without feeding, making them extremely difficult to starve out by simply vacating a room.
Bed bug bites typically appear in lines or clusters of 3-5 on exposed skin — arms, neck, face, and shoulders. While bed bugs are not known to transmit diseases, the bites cause itching, allergic reactions in some people, and significant psychological distress. Many people develop insomnia, anxiety, and stress from bed bug infestations.
DIY treatment of bed bugs is extremely difficult and often counterproductive. Over-the-counter bug bombs and foggers are specifically warned against — they scatter bugs to new rooms and create resistant populations. Professional heat treatment (raising room temperature to 120°F+ for several hours) is considered the most effective single-treatment approach, achieving near-complete elimination in one visit. Chemical treatments by licensed professionals are less expensive but typically require 2-3 follow-up visits.

Frequently Asked Questions About Bed Bugs
Can I get bed bugs from a clean hotel?
Yes. Bed bugs have nothing to do with cleanliness — they feed on blood and can be found in five-star hotels, hospitals, and movie theaters. Always inspect hotel mattress seams and headboards before unpacking, and keep luggage on hard surfaces, not the bed or carpet.
Can I get rid of bed bugs myself?
Bed bug DIY treatment is extremely difficult. They hide in mattress seams, behind outlets, and in furniture joints. Over-the-counter sprays often scatter them to new rooms. Professional heat treatment (raising room temperature to 120°F+) is the most effective single-treatment option.
How do I know if I have bed bugs or flea bites?
Bed bug bites typically appear in lines or clusters of 3–5 on exposed skin (arms, neck, face). Flea bites are usually on lower legs and ankles. Bed bug bites are flat and red; flea bites have a small red halo. Check mattress seams for dark spots (excrement) to confirm bed bugs.
How much does bed bug treatment cost?
Professional bed bug treatment typically costs $300–$1,500 per room. Heat treatment is at the higher end ($1,000–$1,500) but is often the most effective single-visit option. Chemical treatments are less expensive but may require 2–3 visits.
