Bed Bug bites often cause redness and some swelling. Antihistamines and corticosteroids may be given to help relieve the itching. Approximately 50% of Bed Bug victims do not show any evidence of bites.
These tenacious pests are about 3/8″ long and are visible to the naked eye. Amazingly, they are able to go without food for as long as a year. After getting their fill of blood, the females will lay eggs in batches of up to 200 at a time.
Since their reappearance, researchers have found that the new Bed Bugs are much more resistant to chemicals that have previously been in use. Insecticides that are often used for roaches and similar insects are ineffective on Bed Bugs. Bed Bugs, in particular, require professional pest control management.
