Most people do not realize they have been bitten until bite marks appear anywhere from one to several days after the initial bite. The bite marks are similar to that of a mosquito or a flea — a slightly swollen and red area that may itch and be irritating. The bite marks may be random or appear in a straight line.
“People may have bed bugs and not know it because many people have no physical reaction to bed bug bites,” Dr. Harrison says. “That's why it's important for people everywhere to inspect for bed bugs regularly.”
You may have them for a while, but may not notice them until weeks, or even months later. Bed bug eggs take anywhere from six to 12 days to hatch, and the adult life span can be anywhere from six months to a year. That's why it's important to know these early signs of an infestation.
Generally it takes at least seven weeks for a bed bug to grow from an egg to an adult, so there should be no new adults from eggs during that period. Therefore, if many adult bugs are present one can reasonably assume that the infestation has been there for more than seven weeks.
A bed bug showing up a month or two post-elimination is most likely a reintroduction. Studies have shown that bed bugs are highly attracted to previous harborage. In fact, repellency studies have shown some products to have repellency in clean harborages, but not on harborages with previous activity.
Rusty or reddish stains on bed sheets or mattresses caused by bed bugs being crushed. Dark spots (about this size: •), which are bed bug excrement and may bleed on the fabric like a marker would. Eggs and eggshells, which are tiny (about 1mm) and pale yellow skins that nymphs shed as they grow larger. Live bed bugs.
When bed bugs are in their dormant state, they do not need to feed. According to the University of Kentucky, bed bugs can survive 2 to 6 months without a meal. In extreme cases, when the temperature drops to 55°F or lower, they may survive a year or longer.
Bed bugs have another defense system that prevents you from feeling you've been bitten. They inject an anesthetic (numbing) and an anticoagulant (stops bleeding) into your skin when they bite. You may not notice you've been bitten until the bite marks appear, which can take from one to a couple of days after the bites.
However, if there are not too many, then chances are that they will not bite every night. On average bed bugs feed once every 3 to 10 nights and spend the rest of the days resting and digesting their meals.

One bed bug in a home is not always a sign that a significant infestation is present.

Bed bugs are excellent at reproducing and building up their colony size if they aren't fully eliminated. If you used a DIY treatment that didn't eliminate all the bed bugs in the colony, then there's always the chance that they'll remain in hiding until they've reproduced.
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.
