How Can You Become Immune to Bed Bugs?
WouterThere is no known way to become immune to bed bugs. However, there are ways to reduce the risk of being bitten by them. These methods are safe for most people. People who experience a bedbug bite are likely to have a minor reaction to the bug’s saliva. But if you are allergic to the bedbugs’ saliva, you may experience a severe allergic reaction known as anaphylactic shock. Anaphylactic shock occurs when the immune system releases chemicals that cause rapid drops in blood pressure and difficulty breathing. In such an emergency, you should seek medical attention immediately.
Most people who have bed bug bites report itching and red welts. Another half had itching but no welts. Twenty-one percent reported a stinging or pinpricking sensation that could be a sign of bedbug bites. The bites can occur on the hands, feet, chest, and face.
Previous exposure to bed bugs is a factor in determining how quickly people are allergic to the bugs’ saliva. People who have had many bites from mosquitoes are likely to develop bed bug bites, whereas those who have never had an infestation are unlikely to experience an allergic reaction. Prior exposure to bed bugs is also a factor in determining how late a reaction occurs after a single bite.
It is important to remember that bedbugs are nocturnal creatures that live on human blood. They are often attracted to humans, but may also feed on mice or rats. The heat and carbon dioxide from their host’s blood attracts the bugs. Their activity is greatest at night when they feed. Although bedbug bites may be unsightly, they are usually harmless.
