Bedbugs normally feed at night, usually approximately 1 hour before dawn. However, if the conditions are favorable, they also feed during the day. Feeding takes 3-12 minutes. In proper conditions, adult bedbugs can survive without a meal for 1 year or longer. Each female lays approximately 300 eggs in her lifetime. The eggs hatch in 10 days. The nymph stage lasts 6 weeks, undergoing 5 molts.
Discourage bed bug infestation by keeping clutter picked up, washing bedding and upholstery routinely and not buying used furniture. When you’re traveling, lower your risk of bringing bed bugs back home by opening your suitcase on a hotel desk or luggage rack instead of on the bed; keeping your belongings in your suitcase, not unpacked in dresser drawers; sealing dirty laundry in plastic bags that can be taken straight to the laundry room at home; and inspecting your luggage for bed bug activity before you bring it into your bedroom.
Reactions to bed bug bites vary among individuals. Many persons show no signs of bites. Others don’t realize they’ve been bitten until redness and swelling appear around the bite, sometimes with intense itching. Some exhibit inflamed swollen spots that may occur in linear series or have a rash-like appearance. Such bite marks, when they appear, may not show for several days after the person is bitten.
