Life Cycle
• Females lay approximately 300 eggs in her lifetime
• Eggs are pear-shaped and white in color• Eggs attach onto surfaces and hatch
within 10 days to 14 days• Young bed bugs are called nymphs• Nymphs are smaller and lighter in color
than adults• The nymph stage lasts 6 weeks• Nymphs and adult bed bugs live on the
blood of the host (animals and humans)• Adult bed bugs can survive without a
meal for 1 year or longer
BED BUG FEEDING
Bed bugs require blood of animals or humans for growth.
They feed at night when you are sleeping.
They have mouthparts for piercing the skin and sucking blood.
Feeding takes 3-12 minutes.
Bodies swell and become a brighter red after feedings.
Where are Bed Bugs?
Bed bugs are found worldwide.More common in developing countries, but on the rise in the United States due to a number of factors:
• Lack of awareness• Increase in international
travel• Bed bug resistance to
insecticides

– Dormitories
– Homeless shelters
– Hotels
– Military Barracks
• They hide in cracks and crevices during the day.– Mattresses
– Box springs
– Bed frames
– Headboards
– Chairs
– Sofas
Risk Factors
High turnover environments:• Hotels• Hostels• Homeless shelters• School dormitories• Furnished apartments• Multi-family dwellings
*Bed bugs can easily spread where people come and go frequently.
Risk Factors
Recent travel:• Airplanes• Trains• Buses• Taxis
*Bed bugs are thought to be spread by means of luggage and clothing.
Risk Factors
Secondhand furniture in the home:

*Beg bugs hide in items such as furniture and mattresses.
How to Prevent Bedbug Infestations
At home

• Vacuum regularly• Seal cracks, crevices, and
holes in the walls/ceilings/floors

How to Get Rid of Them
Clean everything in the area where the bedbugs were foundVacuum everywhere you can reach with vacuum or hose, pay close attention to cracks/crevicesWash all clothes and linens in HOT water and dry in a HOT dryer
Drying on medium to high heat for 20 minutes will kill the bugs and their eggs120°F
Place linens/clothes in a plastic bag and close it tightlyIn the summer, leave the bags in the sun for a day or close the bags up in the car on a sunny day (120°F)In the winter, leave the bags outside if temperatures are below freezing (32°F), they would have to stay there for several days
How to Stop the Spread
• Avoid items/rooms with known infestations (if possible)
• Do not carry personal belongings into areas with bedbugs
• Items with large populations of bedbugs may need to be thrown out (like couches or mattresses)
• If you’ve been around bedbugs, inspect all clothing, bags, shoes, purses, etc. before bringing them back into your home
How to Stop the Spread
• Bagging these items tightly in plastic bags before entering the home then washing/drying them immediately may be the safest approach
• If this isn’t possible, shake clothing carefully but thoroughly while standing outside before entering your home/car
How to Stop the Spread
Place encasements around pillows, mattresses, and box springs to trap the bedbugs .
