Bed bugs are red brown insects up to 5 mm in diameter that typically live in mattresses and can bite unsuspecting sleepers.
Bedbug bites are typically grouped and may be arranged in a line (so-called "breakfast, lunch and dinner" lesions). They are evident by morning as erythematous wheals, usually very pruritic, sometimes with a central punctum.
Examination of the mattress on its undersurface will usually demonstrate the insect. They are nocturnally active, and tend to disappear during the day.
- The application of a pyrethrin based insecticide on the under surface of the bed is generally highly effective.
- More toxic chemicals that might permanently impregnate the mattress and its occupant are not recommended
