Although bed bugs do not seem to be involved with any serious disease transmission, the bites of bed bugs at night can prove very irritating, even unbearable at times. They are blood suckers at all stages of their development, so a substantial infestation can lead to much biting and annoyance.
If you have been bitten by Bed Bugs while staying at home it is likely you do have a Bed Bug infestation. If you where bitten while travelling perhaps at a hotel or backpackers hostel it is likely that they have a Bed Bug infestation.
To be sure..
