Understanding Bed Bugs’ Feeding Habits
Bed bugs are parasitic insects that feed exclusively on blood. Throughout their life cycle, which can last anywhere from several months to more than a year, they require a blood meal to survive and grow. If they cannot feed on blood, they will not survive for long. Bed bugs typically feed on the blood of humans or warm-blooded animals, and they are most active during the night when their hosts are asleep.
Factors That Attract Bed Bugs to One Person Over Others
Bed bugs do not differentiate between clean or dirty homes, but they are attracted to warmth, carbon dioxide, and certain chemical secretions that humans and animals emit. However, it is not yet entirely clear why bed bugs bite one person in the household over others. The common belief that some people have sweeter blood than others is a myth. However, there are several other factors that could make some people more attractive to bed bugs.
Human Body Heat and Bed Bugs’ Sensitivity to It
Bed bugs are attracted to the heat that our bodies give off. They are most likely to feed in areas where our bodies have a higher temperature, such as the head, neck, and shoulders. If a person sleeps on their stomach or has a hand or foot sticking out of the covers, the bed bugs will be able to sense the heat and will crawl towards the exposed skin to feed.
Factors that can increase your body temperature and consequently bed bug bites can include:
- Hot weather or overheating indoors
- Alcohol consumption
Behavioral Patterns of Bed Bugs
Bed bugs are attracted to individuals who stay still while they sleep. This means that people who move around a lot or who have restless sleep are less likely to be bitten. Bed bugs are also attracted to the carbon dioxide that we exhale. This is why they often bite people who snore and those who breathe heavily.
The Role of CO2 Emission in Bed Bugs’ Attraction
Humans release varying amounts of carbon dioxide (CO2) as they sleep, depending on factors like age, weight, gender, and metabolism. Bed bugs use CO2 as a means of locating their host, and they are sensitive to even small changes in CO2 levels around them. Accordingly, individuals who produce higher levels of CO2 are more likely to attract hungry bed bugs.
Possible Reasons for Varying Responses to Bed Bug Bites
It is not yet entirely clear why some people respond more severely to bed bug bites than others. However, there are several theories. One theory is that people who are bitten frequently develop an immunity to the bed bug saliva that contains an anticoagulant and anesthetics. In contrast, people who are not frequently bitten may have a more exaggerated response when they are. Additionally, some people are more sensitive to the histamine that bed bugs inject into their victims’ skin, which triggers an itchy response.
How to Prevent Bed Bugs from Feeding on You Specifically
Preventing bed bugs from biting you requires several strategies. One step is to make sure that your home is free of bed bugs or any other pests. You should thoroughly inspect your mattress, bedding, and upholstered furniture regularly for any signs of bed bugs. If you suspect that you have bed bugs, hire a pest control professional to rid your home of the infestation. You can also use bed bug-proof mattress covers to reduce the risk of bed bugs biting you.
Additionally, you can try the following tactics to avoid being bitten by bed bugs:
- Reduce your exposure to bed bugs by keeping your home clutter-free
- Use essential oils like tea tree oil and lavender to repel bed bugs
- Wash your bedding regularly with hot water to ensure that any bed bugs that may have found their way into your sheets are eliminated
In conclusion, bed bugs bite anyone they find because they require blood to survive, but only half of those who are bitten respond to the bites. Bed bugs are attracted to warmth, CO2, and chemical secretions that humans and animals emit, and these factors can contribute to why bed bugs bite one person in the household over others. Nonetheless, there are several strategies that you can use to minimize your exposure to bed bugs, including keeping your home clutter-free, washing your bedding regularly, and using essential oils to repel the pests.
