How Old Are Bed Bugs When They Bite?

Bedbugs can bite from their very early stages of life. Even though the eggs are not capable of biting, the bedbug nymphs begin feeding on the blood of human beings within the first few days of hatching. Their tiny bodies feed off the blood and grow very fast. The first bite that a bedbug will make is when it is only 1mm long, or about 3/64 of an inch.

The adult bedbug is a small, oval-shaped bug about 1/5 inch long. Its flattened body has well-developed antennae and a small compound eye. Its pronotum, the area behind its head, contains numerous tiny hairs. Bedbugs have a large life cycle and can lay up to 500 eggs in a lifetime.

After two or three months, bedbugs stop biting and moving. Symptoms of an infestation may be a number of small, itchy bites or a single, scattered bite. Fortunately, the bites of bedbugs can be spotted quickly, allowing you to treat them before they spread.

The bites of bedbugs can appear on any part of your body, but they normally bite exposed skin while you sleep. Your face, arms, hands, and neck will likely be bitten the most. You may also be bitten in your pajamas.
