3 HISTORY OF PROBLEM A problem for 1000s of years Eliminated in US after WW II General use of DDT A major return in past 5 years

4 WHY ARE THEY BACK Increased international travel Change in general pest control methods Reduced available products for control Lack of research and development

5 WHERE ARE THEY FOUND Small tight places Early stages of infestation near the bed Where people spend a lot of time resting Later stages of infestation can be anywhere

6 IDENTIFICATION Not as small as you might think 1.5 mm – 1 cm long, flat, oval, with no wings Brown to Dark Red (Adult) Tan (Newly Hatched)


8 LIFE CYCLE Aid in determining the origin of infestation Determine the severity of problem Treatment alternatives

9 Life Cycle Important Points. –Lays 3 to 5 eggs a day 300 to 500 eggs in lifetime –Total days from egg to adult is about one month at 80.6 ˚ F. –5 molts from nymph to adult –Can live well over 6 months without feeding (some reports over 18 months)

10 TEMPERATURE EFFECTS –Below ~55˚ F Development stops –Above ~99˚ F Development stops –Thrive at temps between ~68˚ F - 80˚ F –Die at Temps > 111˚F or < 32 ˚F

11 INSPECTION/TREATMENT Must be very thorough Can be expensive Can involve disposal of items that can not be effectively treated May require more than one treatment

12 TREATMENT OPTIONS Heat is your best friend Insecticidal dusts are long lasting Some liquid and aerosol products are labeled for bedbugs Isolate to prevent spreading
