Bed Bugs
Bed bugs feed exclusively on blood and may survive a year without eating. They are attracted to body warmth and carbon dioxide.
Signs of Infestation
A more accurate way to identify a possible infestation is to look for physical signs of bed bugs. When cleaning, changing bedding, or staying away from home, look for:
- Rusty or reddish stains on bed sheets or mattresses caused by bed bugs being crushed.
- Dark spots (about this size: •) are bed bug excrement and may bleed on the fabric like a marker would.
- Eggs and eggshells are tiny (about 1mm) and pale yellow skins that nymphs shed as they grow larger.
- When not feeding, bed bugs hide in a variety of places. Around the bed, they can be found near the piping, seams, and tags of the mattress and box spring and in cracks on the bed frame and headboard.
You May Find Bed Bugs:
In the seams of chairs and couches, between cushions, in the folds of curtains.
- In drawer joints.
- In electrical receptacles and appliances.
- Under loose wallpaper and wall hangings.
- At the junction where the wall and the ceiling meet.
- Even in the head of a screw.
Since bed bugs are only about the width of a credit card, they can squeeze into tiny hiding spots. If a crack will hold a credit card, it could hide a bed bug.
Bed Bug Behavior and Habit
Understanding the behavior of bed bugs (how they eat, live, and reproduce) will help you find an infestation before it becomes established and monitor for the presence of bed bugs after your home has been treated.
Feeding:
- They appear to prefer to feed on humans but will also feed on other mammals and birds.
- Will readily travel 5-20 feet from established hiding places (called harborage) to feed on a host.
- Even though they are primarily active at night, they will seek hosts in full daylight if hungry.
- Feeding can take 3-12 minutes.
- The rusty or tarry spots found on bed sheets or in bug hiding places are because 20% of the time, adults and large nymphs will void remains of earlier blood meals while still feeding.
Life Stages/Mating
- Bed bugs need at least one blood meal before the individual bug can develop to the next of the six life stages.
- They can feed more than once.
- Each stage also requires the molting of skin.
- To continue to mate and produce eggs, males and females must feed at least once every 14 days.
- Each female may lay 1 to 3 eggs per day and 200-500 eggs per her lifetime (6-12 months but could be longer).
- The egg-to-egg life cycle may take four to five weeks under favorable conditions.
Living Conditions
- Bed bugs can survive and remain active at temperatures as low as 7°C (46°F), but they die when their body temperatures reach 45°C (113°F). The room must be even hotter than 113°F to ensure sustained heat reaches the bugs no matter where they are hiding.
- Common bed bugs are found almost anywhere their host can live.
- Tropical bed bugs (Cimex hemipterus) require a higher average temperature than the common bed bug and are found in tropical and subtropical areas.
