These are photos of the bed and frame in this home. You can see all of the different stages of bed bugs. The bed bug life cycle is short. A bed bug can go from egg to adult in a few as 40 days if the insects have access to all the blood meals they need. Bed bugs start out as tiny pearl-white eggs about the size of a pinhead. The insects then go through a series of nymph stages where the bug takes a blood meal and then molts. The bugs go through five molts before reaching maturity, and they will not molt unless they've had a blood meal. If not recently fed, nymphs are translucent or whitish-below in color, and are next to impossible to find, unless you are an eagle-eyed bed bug specialist who is actively inspecting for them. Nymphs start out at about 1.5 mm and continue to grow to about 4.5 mm (a little more than 1/8 of an inch) before their final molting. Adult bed bugs are still small 5-7 mm (up to 1/4 inch), or about the size of an apple seed. If not fed recently, they have a flat, oval-shaped body, and if fed, they become filled with blood and look like little water balloons.
