i have a phobia of bedbugs so i did a lot of research
if u think u have bedbugs place a bowl of water under each leg of ur bed and if there are little floating bugs in the morning in the bowl- congrats u have visitors (shudder)
also when in hotels keep ur suitcases zipped at all times and check the beds b4 u go to sleep
when u get home from a hotel wash everything in hot water
(i feel very crawly and itchy right now)
