Bed bugs, scientifically known as Cimex lectularius, are notorious for their persistence and adaptability in infesting homes, hotels, and other spaces where humans reside. These tiny pests thrive on human blood, which serves as their primary food source, although any blood filled animal will be a possible food source. For pest control professionals, understanding the feeding habits of bed bugs is critical to designing effective strategies for elimination. This article delves into the specifics of how long bed bugs feed, the factors influencing their feeding patterns, and why this knowledge is essential for addressing infestations.
The Feeding Process of Bed Bugs:
Bed bugs are nocturnal feeders in most cases, meaning they are most active at night when their human hosts are asleep. That being said though, bed bugs can come out of hiding and feed at any time of the day that presents itself as an opportunity. Their feeding process involves three key steps.
Detection:
Bed bugs use heat and carbon dioxide emissions from humans to locate their host.
Attachment:
Once they find exposed skin, they use their specialized mouthparts to pierce the skin and access blood vessels.
Feeding:
Bed bugs inject an anticoagulant to prevent blood clotting and an anesthetic to minimize the host's awareness of their bite. The anticoagulant and anesthetic are what make peoples bite itch. This will be the case for most blood feeding insects.
On average, a single feeding session lasts 5 to 10 minutes, during which the bed bug consumes enough blood to expand its body by up to three times its normal size.
How Often Do Bed Bugs Feed?:
The frequency of feeding depends on several factors, including the life stage of the bed bug and the availability of a host. Typically:
• Adults: Adult bed bugs feed every 5 to 10 days under optimal conditions. This allows them to digest their meal and prepare for reproduction.
• Nymphs: Nymphs, (immature bed bugs), feed more frequently, requiring multiple blood meals to progress through their five developmental stages before reaching adulthood.
Despite their regular feeding needs, bed bugs can survive without a blood meal for several months. Adults may persist for up to a year in dormancy, making infestations difficult to eliminate without targeted treatment. Dormancy is also called diapause.
Factors Affecting Feeding Duration:
Several factors influence how long and how effectively bed bugs feed:
Host Movement:
If the host moves during feeding, the bed bug may disengage and seek another spot, or just plain go back into hiding temporarily, prolonging the process.
Environmental Conditions:
Warm temperatures and low humidity levels favor more frequent feeding, while extreme conditions may reduce activity. Simply keeping the temperature below 69 degrees F will slow feeding habits down as well. Not just feeding habits though, but the amount of mating, eggs lain and how fast they can move, slows down when below 69 degrees F.
Population Density:
In heavily infested areas, competition among bed bugs can shorten feeding times as they vie for access to the host.
Implications for Pest Control Professionals:
Understanding the feeding habits of bed bugs is essential for effective control measures. Here's why:
Detection and Monitoring:
Knowing when and how bed bugs feed helps pest control specialists identify infestations using monitoring devices like CO2 traps or heat lures. Fyi: Most pest control companies will not use these types of traps simply because they are not needed for most infestations to be eliminated. Glue traps are better suited and less expensive ways to detect after an infestation that has been exterminated and you're just trying to make sure they are gone for good.
Treatment Timing:
Bed bugs are most vulnerable during feeding, making nocturnal treatments or interventions that disrupt their activity cycle particularly effective.
Residual Control:
Since bed bugs can survive long periods without feeding, treatments must address not only active feeders but also hidden populations in dormancy. Heat remediation can destroy an entire population in one day but insecticides that are effective need to be applied as well for preventative measures after the heat.
Conclusion:
Bed bugs feed on human blood in sessions lasting 5 to 10 minutes, with feeding frequency varying by life stage and environmental conditions. The younger the bed bug the more often they have to feed on blood. For pest control professionals, understanding these feeding dynamics is critical to devising effective strategies for detection, treatment, and long-term prevention. By leveraging insights into their behavior, specialists can help clients reclaim their spaces from these persistent pests.
