Bed Bug Bites Appearing Days Later: Treatment to Use

Bed bugs are small, flat, and oval-shaped insects that feed on human blood. They are reddish brown in color and can be as small as a sesame seed or as big as an apple seed. Just like fleas, bed bugs can cause rashes in humans. The rash appears similar to the bites of other common insects such as mosquitoes or ticks and is often found on your hands and arms.

Bed bugs are nocturnal, so they tend to bite people at night while they are sleeping. Bed bugs do not fly but they can crawl quickly, which makes it easy for them to get into your home or hotel room in luggage, furniture or clothing.

Bed bug bites are not always easy to identify because they tend to look like other insect bites. You may also see two red dots where the bed bug has bitten you. This can happen if there was an allergic reaction to the saliva of the bed bug or if there was a secondary infection after being bitten by one. In most cases, bed bugs leave behind a rash when biting someone; however, some people may not experience this type of reaction at all when bitten by a bed bug because their skin does not break when being bitten by one.

Where Do Bed Bug Bites Appear?

Bed bug bites can appear anywhere on the body, but they are often found on the arms and legs. They can also be found on other parts of your body, such as your face or torso. Bed bug bites may also occur in areas where you did not sleep such as near doors or in closets.

Bed bug bites are caused by an allergic reaction to the saliva that bed bugs inject when feeding. This saliva is injected into their host’s bloodstream during feeding, leading to a raised red bump with a small central blister known as a wheal (similar to mosquito and flea bites). The bite will become itchy within 24 hours of being bitten by a bedbug and then develop into an inflammatory red welt after 72 hours (Stuenkel et al., 2016).

Why Do Bed Bug Bites Appear Days Later?

The most common explanation for a delayed reaction is an allergic reaction to the saliva injected by the bed bug when it bites. This can cause itching, redness, and swelling that are typically at their worst two to seven days after being bitten.

There are many other possible reasons for delayed reactions, however:

  • You could be having an allergic reaction to something else entirely (such as food or even laundry detergent). If you have allergies, you might want to see your doctor about this possibility.
  • You may be experiencing hives from stress or anxiety about your bed bug situation. Try taking a deep breath and relaxing before rushing off for medical treatment.

What to Do If You’re Experiencing Delayed Reactions to Bed Bugs Bites

If you are experiencing delayed reactions to bed bug bites, it is important that you call a pest control professional to help you treat the problem. There are various treatments that can be used, and these treatments take time to work. Some of them are not suitable for use in homes with young children or pets. It is highly recommended that you do not try to treat the problem yourself.

How Do You Know If You Have Bed Bug Bites?

Bed bugs are insects that feed on the blood of humans and animals. They are very small, typically 4-5mm in length, and are generally brown in color but can be a variety of colors including red, black, and yellow. They feed on their host while they sleep so any bites or marks would be most likely to appear at night when the host sleeps. The bite itself is not painful but can become itchy after a few days as well as causing rashes or swelling where the insect has bitten. It will take several hours for the bite mark to show up due to how sensitive it is on your skin compared with other types of insect bites such as mosquitoes which will appear within minutes after being bitten by them.
