Bed bugs are very resilient. Nymphs and adults can persist months without feeding which is unusual for most insects. The ability to survive without a blood meal is longer at cooler temperatures ― potentially up to a year or longer at 55°F or less. In temperature-controlled buildings, a more typical duration is about 2 to 6 months. Consequently, it is usually impractical to leave buildings unoccupied in hopes of ‘starving out’ an infestation. When infested dwellings such as apartments are vacated, bed bugs often disperse to nearby units, or reduce their activity until the unit is reoccupied.
Before you run off and buy every cream the pharmacy stocks, you’ll want to confirm that the marks are actually from bed bugs. Even if they match the description – round, red marks that may bump, swell, itch, and/or burn – the marks could be allergic reactions to food or fabric, irritations from a rough material, or bites from another pest like mosquitoes or carpet beetles.
Insect and spider bites and how to deal with them Insect and spider bites can occur almost unnoticed, or they can be painful. Either way, home treatment is usually enough for most symptoms. However, some bites can spread serious disease, such as Lyme disease and malaria. Find out how to protect against bites and what to do if someone has a severe reaction to a bite. Read now
Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
