What are the symptoms of a bed bug bite?

Bed bug bites are often itchy and can cause redness, burning, swelling, and irritation. As noted above, bed bug bites may also lead to infections due to scratching.

The symptoms depend on your individual reaction to bed bug bites as you may not even experience any symptoms at all while others may have severe reactions.

The site of the bite may look red and swollen with a dark spot in the middle. They usually occur in clusters or in a line and may become a fluid-filled blister.

Sometimes you may notice blood on your sheets from excessive scratching of the site of the bite.

Bite marks do not always show up immediately and may take several days to form.

Bed bugs can bite anywhere on your body; however, the bites are usually on areas of your skin that are exposed when you sleep.

What causes bed bugs?

Bed bugs are often found in mattresses, bedding, clothing, luggage, box springs, and furniture.

They can also be found in other places where people sleep and come and go frequently such as hotels, dormitories, barracks, hospitals, cruise ships, shelters, and even your own apartment building if you live in one.

These insects are most active at night when they come out to feed on your blood.

How do I know if I have a bed bug infestation?

Besides finding a bed bug bite or a bed bug, there are several common signs of bed bugs to tell if you have a bed bug infestation and these include:

Dark specks on your mattress

One obvious sign you may find are dark specks on your mattress or the mattress seams which is the excrement of the bed bug

Small yellow specks

Bed bugs molt 5 times in different life stages so you may find small yellow specks which are skin castings and are another physical sign of their presence

Small blood spots on your sheets

These blood stains are caused by itching the bite sites and causing them to bleed

How do you treat a bed bug bite?

If you have bed bug bites, the best thing to do is to leave them alone and let them heal on their own, which can be one or two weeks.

Resist the urge to scratch as this can cause the bites to become infected.

You can also try using a cold compress or taking an over-the-counter antihistamine, such as Benadryl, to help with the itchiness.

Over-the-counter hydrocortisone topical creams may also help with the itching.

If the bites are causing you a lot of discomfort, you can see your doctor or dermatologist for further treatment.

How do you get rid of bed bugs?

If you think you have bed bugs, it is important to contact a professional pest control company for help as bedbugs are difficult to get rid of and most likely will not go away without one.

The exterminator will likely need to use a combination of pest control technology including chemical and non-chemical treatments such as vacuuming, steam treatments, and using pesticides.

They may also use liquid nitrogen to freeze and kill the bugs too.

Any clothes, bedding, linens, or drapes that are infested need to be laundered in the hottest water possible.

If you are in a hot area, you can even put these items in a sealed bag in a parked car in the sun for a day with the goal being to get the inside of the car to 115°F or 46°C.

If you can't launder certain items and are not in a warm area, you can also kill bed bugs by freezing the items for a few days at 0°F or -17°C.

If you have a severe infestation, you may need to throw away a mattress, box spring, or certain pieces of furniture, but make sure to clearly mark them and not leave them where someone else may take them.

Lastly, you can also seal any holes in your floorboards around the infestation as bed bugs could be hiding there too. The pest control professional will also be able to tell you how to prevent bed bugs from returning in the future.
