If you spend the night somewhere else, like a hotel
, make sure you don't bring them home with you in your baggage and clothing. If you have brought them home, you may smell a sweet fragrance - this is produced by glands of the bed bug.
One way to try to stop being bitten and infested is to use an insect repellant at night. However, you must still make sure that your home is free from bed bugs, as they multiply quickly, and once you've got them, they're difficult to get rid of. If you do find you've got them in your home, then it may be a good idea to employ a pest control firm who will spray your home with an effective formula which should get rid of these parasites for a long time.
