Bed Bug Basics

​Bed bugs are small wingless insects that do not fly​
​They depend upon blood from animal hosts as their sole source of food. (Feed ~every 5-10 days)
​They are flat, oval shaped, and a mahogany color as an adult​
​They can wedge themselves into any crack or crevice​
​They are most often nocturnal, but will come out in the day if an area is dark and they sense food is near​
​Most people are not awakened by bed bugs while being bitten.  ​ Not everyone will show signs of being bitten
​Adults have been shown to live over a year with no blood meal​
​They can survive sustained heat and cold if given time to adjust​
​Not considered a filth pest.  ​ No “grooming behavior” meaning ingestible insecticides do not work​
​Females typically lay about 5-7 eggs a week/500 eggs in lifetime​
​While some pathogens have been found in the gut of bed bugs, they have not been shown to transmit diseases to humans
