• Great Hitchhikers
HISTORY OF PROBLEM
•A problem for 1000’s of years
•Eliminated in US after WW II
•General use of DDT
•A major return in past 5 years
WHY ARE THEY BACK
• Increased international travel
• Change in general pest control methods
• Reduced available products for control
• Lack of research and development
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
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)
OBSERVE THE SAMPLES
LIFE CYCLE
• Aid in determining the origin of infestation
• Determine the severity of problem
• Treatment alternatives
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)
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
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
TREATMENT OPTIONS
• Heat is your best friend

MYSTERY BITES
• Not all welts and irritation are caused by insects
• Detailed inspection with magnifier (10X)
• Sticky boards helpful
• Detailed questionnaire
OTHER BITING INSECTS
• Fleas• Lice• Mosquitoes• Sand Flies• Mites
– Associated with animals– Chiggers– Dust
NON-INSECT IRRITANTS
• Household Products
– Soaps, detergents, cleansers
– Cosmetics, hair products, medications
– Paper, cardboard, printing inks, clothing
NON-INSECT IRRITANTS
• Environmental Factors
– Multiple people itching
– Tiny fragments of paper, fabric, insulation
– Irritation may worsen with low humidity
NON-INSECT IRRITATIONS
Medical Conditions
– Symptoms associated with diabetes, liver, kidney and thyroid disorders
– Food allergies, prescription and recreational drugs, and stress
– Power of suggestion
