Eggs Bed Bug eggs are grain like and white in color. Their minuscule size makes them hard to detect to an untrained eye, egg size is about 1 mm in length. Bed bugs will lay between 1 and 5 eggs per day and eggs can be in clusters or individually. Bed bug eggs can be found in tight cracks and crevices for added protection. Within two weeks the eggs will hatch and immature bed bugs will be searching for their first blood meal.
Nymph Bed bug nymphs go through 5 stages before reaching maturity. At each stage the bed bug will molt, in order for a bed bug to molt to the next stage it will require a blood meal. Advancing through nymph stages doesn’t take long, about 21 days before reaching full adulthood. Adult bed bugs are capable of surviving for months without a blood meal.
Adults Unfed adult bed bugs are a dark rusty brown color, thin oval shape similar to an apple seed.
Fed adult bed bug are a red brown color and their body becomes elongated and engorged after consuming a blood meal.
Feeding Bed bugs are attracted to carbon dioxide that is emitted by their host. This is why bed bugs typically tend to feed during the night on exposed skin. However, if the area is heavily infested or the opportunity arrives during the day, they won’t pass up a potential meal.
It takes about 5-10 mins for a bed bug to consume its blood meal, after which it will be engorged and seek secluded shelter where it will hide out for 5-10 days. During this period, the bed bug will be digesting its meal, mating and laying eggs.
How They Eat Bed bugs have two beak like tubes that they use to consume a blood meal. The first tube will inject the host with the bed bug’s saliva which contains an anesthetic, this will help numb the area and often times the bite will go unnoticed during the feed. The second tube is used for drawing up blood.
