Where Do Bed Bugs Come From

Bed bugs reach their host by crawling or sometimes jump down from ceilings. The jump down when they feel a heat wave which attracts them. They would also gravitate to a spot where they feel there is a source of carbon dioxide, like in human breathing. The biting and sucking action of the bed bug is achieved by its piercing the skin on the host it is on, probably you, by using two hollow tubes. Through one of them it injects anticoagulants and anesthetics while from the other it removes the blood from the host which make up its food. The feeding time is about five minutes after which it will go back to its hiding place. Because of this anesthetic action a bed bug bite is only felt a few hours after the bed bug has had its fill. The first reaction is an uncomfortable itch. Their normal feeding cycle is every week or so, even though bed bugs are known to survive for up to a year without feeding.
