Bedbugs also known as Cimex lectularius, belong to the family of Cimicidae. They are actually small parasitic insects that feed on the blood of warm-blooded animals.

Bed bugs are small and oval in shape bearing a darker brown when mature and reddish after feeding. Their lifespan varies from species to species and also from their feeding and they can grow up to 5mm in length and 3mm in width. They're able to crawl at a very fast pace to compensate not being able to fly.

Bedbugs dwell in areas of the home and as the name implies, they mostly inhabit in beds, including mattresses, bed frame etc. Bedbugs can survive in a wide range of conditions such as surviving at temperature as low as 16.1 degrees celsius or as high as 40 degrees celsius. They prefer feeding at night and hate the sunlight. However they will feed even in the day time when required. Bedbugs are attracted to to their hosts primarily by carbon dioxide (CO2), then by warmth. Bedbugs can live for up to a year without feeding but they will normally try to feed every few days unless conditions do not permit (making them able to survive in desolated areas).

After having some knowledge about the bedbugs, now let's talk about the symptoms of being bitten by them and the eradication of them.

When you are bitten, the bitten area will turn red and become swollen, often accompanied with intense itching (normally caused by the saliva of the bedbugs). It is similar to a mosquito bite, red, swollen and itchy making it difficult to distinguish. You're tend to be bitten by bed bugs in a roll, normally 2 to 3 bites in a row. The possible reason is that the bed bugs are disturbed while feeding (turning over,scratching etc) making the bed bugs have to leave its host before returning back again to feed and biting on a different area. Another reason might be that it is trying to find a vein where it can get lots of feed (blood) from, thus trying several attempts to find the right spot.

The common symptoms as mentioned would be redness, swelling and itching at the area of the bite. In some rare cases, anaphylatic reaction may occur such as causing an asthma attack.

So how do you eradicate these nasty bugs??

Pesticides, vaccuumming and also high heat. Pesticides can be a real help to remove those bedbugs that have not been expose to pesticides before (not often seen nowadays) as there have been an increasing resistance to pesticides. So more people are opting for vaccuuming where bed bugs are. By vaccuuming every single corner of the house which is possible for it to inhabit or using high heat (above 46 degrees celsius), it is possible to leave your house bedbug-free. High concentration of carbon dioxide has been proven to kill bedbugs too!
