Bedbugs: Life Cycle of Bed bugs

Bed bugs are insects that live on the blood of animals or humans, usually at night. Adult bedbugs have flat bodies about the size of an apple seed. After feeding, however, their bodies swell and are a reddish color. Bedbugs do not fly, but they can move quickly over floors, walls, and ceilings. Female bedbugs may lay hundreds of eggs, each of which is about the size of a speck of dust, over a lifetime.

Immature bedbugs, called nymphs, shed their skins five times before reaching maturity and require a meal of blood before each shedding. Under favorable conditions, the bugs can develop fully in as little as a month and produce three or more generations per year. Although they are a nuisance, they are not thought to transmit diseases.

Their bites can result in a number of health impacts including skin rashes, psychological effects, and allergic symptoms. Bed bug bites may lead to skin changes ranging from small areas of redness to prominent blisters. Symptoms may take between minutes to days to appear and itchiness is generally present. Some individuals may feel tired or have a fever. Typically, uncovered areas of the body are affected. Their bites are not known to transmit any infectious disease. Complications may rarely include areas of dead skin or vasculitis.


How to Controlling of Bedbugs?

  • Clean bedding, linens, curtains, and clothing in hot water and dry them on the highest dryer setting. Place stuffed animals, shoes, and other items that can’t be washed in the dryer and run on high for 30 minutes.
  • Use a stiff brush to scrub mattress seams to remove bedbugs and their eggs before vacuuming.
  • Vacuum your bed and surrounding area frequently. After vacuuming, immediately place the vacuum cleaner bag in a plastic bag and place it in a garbage can outdoors.
  • Encase mattress and box springs with a tightly woven, zippered cover to keep bedbugs from entering or escaping. Bedbugs may live up to a year without feeding, so keep the cover on your mattress for at least a year to make sure all bugs in the mattress are dead.
  • Repair cracks in plaster and glue down peeling wallpaper to get rid of places bedbugs can hide.

Life Cycle of Bed Bugs

1. Egg: The life of a bed bug begins when they lay grainy, pearl white eggs. A female adult bed bug lays 250 to 300 eggs in their life span. Bed bugs lay eggs in clusters in the cracks of floors and nooks. After one or two weeks, these eggs hatch into nymphs and they start scouting for mammals to begin their feeding.

2. Nymph:There are 5 stages that nymphs will go through. It takes around 5 weeks till the nymphs become adults. The stages are as follows:

  • Nymph Stage 1: Nymphs are newly hatched bed bugs and generally measure up to 1.5 mm. Once hatched, these newborn insects start feeding immediately. Since they are immature newborns, they feed on mammals for blood till they transform into reproducing adults.
  • Stage 2: After the first stage of molting, the nymph becomes 2 mm long.
  • Stage 3: After another stage of molting, the nymph turns 2.5 mm long.
  • Nymph-Stage 4: By now, the nymph has undergone several stages of molting, the bed bug becomes 3 mm long.
  • Nymph Stage 5: This is the last stage of the nymph phase, with the nymph measuring 4 mm long.

3. Adult: After five weeks of maturation, the adult bed bug measures up to 4.5 mm long. When the bed bug reaches this stage, it is capable of breeding and reproducing. An adult bed bug is expected to live for four to six months. When the bed bug measures 4.5 mm, they are ready to mate and start the whole life cycle again.
