Bedbugs have a food preference, humans. This preference is so strong that they are more likely to travel a good distance to seek humans than feed on a pet that is easily accessible. Women and children are generally more sensitive to bites, although men do get bitten. Two people can even sleep in the same bed, and one person will be bitten while the other is not, though it is more likely that both are being bitten, but one is more sensitive to the allergen in the bedbugs saliva than the other person. Tasty tidbit. The most likely time for bedbugs to feed is just before sunrise.
