What are bed bugs?
Bed bugs are insects that, as adults, have oval-shaped bodies with no wings. Prior to feeding, they are about 1/4 inch long and flat as paper. After feeding, they turn dark red and become bloated. Eggs are whitish, pear-shaped and about the size of a pinhead. Clusters of 10-50 eggs can be found in cracks and crevices. Bed bugs have a one-year life span during which time a female can lay 200-400 eggs depending on food supply and temperature. Eggs hatch in about 10 days.
What do bed bugs feed on?
Bed bugs prefer to feed on human blood, but will also bite mammals and birds. Bed bugs bite at night, and will bite all over a human body, especially around the face, neck, upper torso, arms and hands. Bed bugs can survive up to six months without feeding. Both male and female bed bugs bite.
Can I get sick from bed bugs
There are no known cases of infectious disease transmitted by bed bug bites. Most people are not aware that they have been bitten but some people are more sensitive to the bite and may have a localized reaction. Scratching the bitten areas can lead to infection.
How do bed bugs get into my home?
Bed bugs are often carried into a home on objects such as furniture and clothing. If you think you have a bed bug problem, check for live bed bugs or shells in the following areas:
- Seams, creases, tufts and folds of mattresses and box springs
- Cracks in the bed frame and head board, in dresser drawers, shelves and night stands
- Under chairs, couches, beds, dust covers
- Between the cushions of couches and chairs
- Under area rugs and the edges of carpets
- Behind baseboards, and around window and door casings, between the folds of curtains
- Behind electrical plates and under loose wallpaper, paintings and posters, in cracks in plaster.
Bed bugs can also travel from apartment to apartment along pipes, electrical wiring and other openings. If the infestation is heavy, a sweet smell may be noticed in the room.
How do I treat bed bug bites?
Most bed bug bites go away by themselves and don’t need treatment. Keep the skin clean and try not to scratch. If the bites are very itchy, your doctor may prescribe cream or antihistamines to relieve the itchiness. Oral antibiotics may be prescribed for any secondary skin infection from excessive scratching.
- The most common rash is made up of localized red and itchy flat lesions. The classical bed bug bites could be presented in a linear fashion in a group of three, which is called “breakfast, lunch, and dinner”.
- Small raised red swelling lesions are also common.
- In rare cases, people may develop large raised, often itchy, red welts.
- In people with high sensitivity to bed bug saliva, people may develop a lump filled with blood or fluid.
Bed bug bites most commonly occur on exposed areas of the body, including face, neck, hands, arms, lower legs or all over the body.
What do bed bug bites look like?
When bed bugs bite people, they inject their saliva into the biting area, causing the skin to become irritated and inflamed. Individual responses to bed bug bites will vary. The skin lesion from bed bug bites may go unnoticed, or be mistaken for flea or mosquito bites or other skin conditions.
A few bed bugs can become a large infestation quickly. One female bed bug may produce up to 500 offspring during its lifetime, and three generations can live per year. Imagine how many bed bugs you’d have in a year if just one reproductive pair finds its way into your home. As with any pest, knowing its life cycle will help you eliminate it. Bed bugs undergo incomplete metamorphosis.
Egg – The female lays her eggs, usually in clusters of less than 50. She uses a sticky substance to glue her eggs to rough surfaces. Eggs hatch in 1-2 weeks.
Nymph – The nymph must consume a blood meal before it can molt. It molts 5 times to reach adulthood. In warmer temperatures, the nymph stage may last just 3 weeks; in cooler temperatures, nymphs may take many months to mature.
Adult – Adult bed bugs live about 10 months, though some may live substantially longer
