It is important to understand how long bed bugs feed on you. Bedbugs can feed for up to a month and will shed their shells in between feedings. They do not burrow into your skin and can come out on their own at night. They do not need a colony, but do group together in good hiding places.
In the absence of a human host, bedbugs can survive for a few weeks or even months. If they’re living in ideal conditions, bedbugs can survive for between 20 and 400 days without feeding. However, a bedbug will most likely die within two to three months due to starvation.
If you notice a bite, try to find the source of it. The bites are usually small and may appear as a cluster of three, or they may be scattered. In some cases, bedbugs don’t bite at all, but their bites can be very itchy and uncomfortable. You should treat the bite site with a steroidal antiitch cream. You may also want to apply a topical anesthetic.
Bedbugs don’t feed on a regular schedule, and they do not leave the same place every day. They only feed when they are hungry, and then return to their hiding spots. Bedbugs are not active during the day, but they are active at night. They feed for two to five minutes before they molt. If left unchecked, bedbugs can live for a year or more.
