Can bed bugs lay eggs in your underwear?

If you wear underwear to bed, yes, it is possible, though perhaps unlikely. But more importantly if you leave your underwear any of your clothes near your bed, such as on a chair or on the floor or even in a drawer , or if you leave your clothes in your holdall or suitcase or back pack but it is slightly open, it is very normal for female bedbugs to climb inside and lay eggs in there while he is fast asleep in his hotel bed.

This is the most common way that people can bring bedbugs home. A person may stay in a hotel on holiday where there is a minor bedbug infestation and one or more female bedbugs may lay a few eggs inside that person's luggage perhaps on a hard surface underneath his underwear packed therein. The eggs which look like a miniature grain of salt stuck to a hard surface will probably not be seen when you complete packing your luggage in the morning.

So after you check out of the hotel in the morning and travels home you bring your luggage with you. On arrival back home you bring your luggage into your bedroom at your home and unpack there, probably still not seeing the tiny eggs still stuck at the bottom. So perhaps during the following night those bedbug eggs that were laid in the hotel will now hatch. New bedbug nymphs will thus be born in the person's home.

Each nymph will immediately detect the CO2 breathed out by you or else other people asleep in that home and be attracted to your or their beds for its first meal of the bed occupant's blood. So within a few weeks the nymphs will have become an adult and breed in the bed or elsewhere in the home home, the bedbug population multiplying rapidly over next few months. So that home which was previously free of bedbugs will soon have a major bedbug infestation, all resulting from that laying of its eggs in your luggage during that stay in that hotel and then bringing your clothes and luggage home.
