Question: how long does it take to notice you have bed bugs?
Answer: Nymphs resemble adults but are much smaller. In order to grow, or molt, nymphs must acquire a blood meal. Depending on the temperature, it takes nymphs about 100 days for the five molts to occur before mating can take place. Roughly 1.5-2 months are required for a complete cycle from egg to mated adult bed bug.
