A bed bug does not actually live under your skin, but will simply drink a few drops of blood while you are sleeping. You cannot feel its bite, even though it is actually piercing the skin. Although some saliva will get into the bite, bed bugs are not known to pass on any diseases to humans.
The different species of bed bugs have different feeding preferences. Some prefer human blood while others prefer bats and birds. Bed Bugs primarily reside in their target's nests or nesting areas.
While many bed bugs hide in mattresses, some may also hide in a sofa or chair, or behind wall paper or pictures. Thoroughness is the only real way to get rid of Bed Bugs. Every corner and crevice needs to be searched. As you might guess, this means that simply getting rid of an infected mattress will not completely solve the problem.
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.
