Bedbugs tend to bite exposed regions of the skin to feed on a person’s blood. A pesticide called DDT was used to eradicate bedbugs from developed nations of the world; however, the pesticide was later banned due to its high toxicity.
Due to the increase in international travel, bedbugs have become a common problem in many parts of the world again. People who spend time in places where there are many nighttime guests such as hotels, homeless shelters are and hospitals are more likely to encounter bedbugs, and possibly bring them to their own homes as well.
Bedbugs are oval, flat and reddish brown in color with the size of an apple seed. During daytime, they usually hide in box springs, cracks and crevices in your beds, bed frames, behind picture frames, headboards etc. If you suspect that you may be having bedbugs in your home, it is advisable that you call a professional exterminator.
It can be difficult to differentiate between a bedbug bite from any other insect bite, but usually the region affected by the bedbug will be:
- Red, usually with a dark spot in the middle
- Arranged in a cluster or line
- Located on the neck, face, hands or arms
Some people often do not have a reaction to bedbug bites, but many often experience allergic reactions such as severe itching, hives and blisters.
