What are bed bugs?
Bed bugs are parasitic insects that feed on the blood of people and animals during sleep but are NOT considered to be medical or public health hazards. These insects have not been found to spread disease. An adult is typically 5-7mm long.
Traditionally bed bugs have been problematic in developing countries but recently have been spreading rapidly throughout the United States, Canada, the United Kingdom, and other parts of Europe. They tend to be found near areas where people sleep, including hotels (even 5-star resorts!), cruise ships, apartments, dorms, buses, trains, and other areas where a large number of people may sleep. New infestations primarily occur through inadvertent transport of bed bugs on personal items, furniture, and luggage.
Signs of bed bugs
- Bite marks on the face, neck, arms, hands, or other body parts while sleeping. These marks tend to appear in a row or line, are very itchy and typically develop 1-14 days after being bitten. Bite marks generally take 3-6 weeks to heal. The bite itself is generally painless.
- Bed bug exoskeletons after molting.
- Bed bugs found in mattress and sheet folds.
- Rusty-colored blood spots due to blood-filled fecal material excreted by bed bugs on the mattress, headboard, bed frame or nearby furniture.
- Sweet musty odor.
For the majority of people, bed bugs are not a serious medical threat. In the majority of cases, the following steps are all that is needed.
- Do not scratch the bites. Scratching increases the risk of infection.
- Apply an antiseptic cream or lotion to the bites. • Take an over-the-counter antihistamine such as diphenhydramine (Benadryl), cetirizine (Zyrtec), loratadine (Claritin) or fexofenadine (Allegra) as needed to help with itching.
- Use an Anti-itch lotion per package directions.
- Use over the counter hydrocortisone cream or ointment per package directions.
