Bed bug bites are painful and getting rid of the blood-feasting pest isn’t easy. Here’s everything you probably need to know about bed bugs.
What Are Bed Bugs?
Bed bugs (Cimex lectularius) are six-legged, flat, oval-shaped, small, wingless insects. They suck blood from humans or animals and range from white to brown colors. Soon after they feed, their apple seed like body swells and attains rusty red color.
Usually, their maximum size is 0.5 centimeters, and they are visible to the normal eye if you observe closely. Bed bugs infer their name from their favorite hiding place, namely bedding or mattresses. They have a flat body as thin as a credit card and hence can squeeze into tiny spaces.
These bed bugs tend to live in groups in their hiding places. Their existence does not signify that your home is dirty, as they are also found in most immaculate places. You need to remember the fact that they feed on blood and not on dirt, making it a possibility to exist wherever blood-loaded humans are there.
Where Are Bed Bugs Mostly Found?
Bed bugs are annoying for both homeowners and businesses such as hotels, dorms, hostels, and hospitals where people rest on beds at night. Sometimes they are also found in colleges, universities, retail stores, libraries, movie theaters, and such places that are crowded and where people sit for a considerable time.
In other words, bed bugs can be found in most common items or places.
Where Do Bed Bugs Come From?
The most common cause of bed bugs infestation, recognized as of now, is travel. Flat bodies and the plain non-prominent color give them profuse camouflage to hitchhike safely and obscured.
The bed bugs are common in developing countries and are becoming common in developed countries due to international travel. They hide in the apartments, shelters, hotel rooms, and in most of the crowded places. These little creatures attach themselves to the clothes, luggage, furniture, pets, and other objects using which they transport themselves from one place to another.
The increasing number of people are traveling from many countries where people come from distant locations for jobs, or they travel for a vacation. During these visits, their belongings inadvertently get infested and eventually carry back these bed bugs to their place, spreading the infestation.
Can Bed Bugs Fly?
Though they cannot fly, they do have a knack of moving swift enough to disappear in a jiffy. It does not matter wherever you spot these bugs; they are gone in a blink of the eye. Every surface like a floor, bed, ceiling, wall, and any such surface they maneuver with the same lightning speed.
How Fast Could Bed Bugs Breed?
Female bed bugs lay eggs, and these eggs develop into nymphs. These nymphs need to shed their skin five times before they attain maturity. This skin shedding process can occur only after they feed on blood, and it can be completed in months. The nymph successfully develops into mature bed bugs, depending on its feeding aptitude.
However, once they turn into adults, the female bed bugs can lay hundreds of eggs over their lifetime of 10 months and produce three generations per year. The size of their egg is just of a dust speck of 1mm size and white.
The female bed bugs can lay one to five eggs every day and lays from 200 to 500 eggs in a lifetime. They lay their eggs in tight cracks, and these eggs hatch into nymphs in two weeks.
As mentioned above, bed bugs will be ready for feeding on this stage and need to pass four instar stages shedding five molts before becoming an adult. They need room temperature and at least five weeks to complete this process apart from the constant feeding. 
Do Bed Bugs Bite?
Yes, bed bugs do bite their host, but you cannot feel their bite as they inject a numbing agent before they feast on you. Interestingly, this numbing agent also contains an anticoagulant that allows the blood to flow freely, causing otherwise clots due to the natural body defense mechanism when wounded.
They leave straight rows of red, itchy bite marks, and that is the only way for you to know that you are bitten by bed bugs. As they sneak out only during your deep sleep time and do not sting, these bite marks are the sole identifying factors to start a scavenger hunt. Their biting activity is at peak just before the dawn, and their usual places of attack include arms or shoulders.
They pierce your skin and draw blood using their elongated beak. Though most of the bugs feed for three minutes, there are instances of feeding up to 10 minutes.
How To Treat Bed Bug Bites?
Bed bugs bites are not infective by themselves though they are itchy. However, if you scratch, there is a chance of secondary infection. You can apply any antibiotic cream/ ointment or antiseptic lotion to alleviate the itching. 
If the itch is unbearable, you may consider oral antihistamines and corticosteroids, which will usually suffice. Nonetheless, if you still experience symptoms, it is best to visit a doctor.
What Do Bed Bugs Feed On?
Bed bugs are nocturnal creatures and hide throughout the day in beds, furniture, paper trash, wood, and floors during the day. During the night time, they feed on human blood when they are fast asleep. They are incredibly proficient at feeding on their prey at the most unnoticed hour of the night.
Bed bugs require at least three minutes of feeding before they are full, and soon after, they return to their hiding place for digesting their meal. Once full, they become engorged to an extent where they drop off from the host body, as they can no longer engage themselves. They can live for weeks without feeding.

Make sure you use as much heat as possible without damaging your clothes.

- Vacuum under and around the bed using a disposable bag and make sure to detach the waste bag and place it tightly sealed in a plastic bag. Discard it soon into the garbage bin outdoors.
- Cover the mattress and the box springs using a tightly woven zippered encasement preventing the bugs from entering or leaving the mattress.
- Plaster the cracks in the wall and repair the wallpaper where it is peeling using the glue, leaving no place for them to hide.
