Treat Bed Bug Bites

Bed bug bites can be annoying, but luckily, they are easy to treat. This article will give you a few remedies. Before you try to treat the bites, however, make sure that bed bugs are responsible.

10 Second Summary

1. Apply wet soap to the bite and allow it to dry.
2. Try a home remedy, such as baking soda and water or lemon juice.
3. Consider a steroidal anti-itch cream or calamine lotion.
4. Take an oral antihistamine or pain relief medication if needed.
5. See your doctor if the bites become infected or do not clear up within 1 to 2 weeks.

Steps

Identifying a Bedbug Bite

  1. Inspect the bites carefully. Bedbug bites commonly resemble other insect bites, including mosquito bites. They typically involve a raised, reddish bump but can also appear as a blister. Bedbug bites are very difficult to distinguish from other insect bites; even a clinical physician cannot usually diagnose bites simply by looking at them.[1]
    • Bedbugs do, however, have a unique bite pattern. Although some bites may appear alone, most bites occur in a row of three to five bites (termed "breakfast, lunch, and dinner") or in a cluster of red bumps (a rash called bedbug dermatitis). The bites often appear in a zig-zag formation, but may appear in a straight line if the bugs bite you in the morning.
    • Bites tend to occur on exposed areas of the body, such as the neck, face, feet, and arms. In contrast to mosquito bites, bedbug bites rarely occur on the back of the knees or in the folds of the skin.
    • The bumps or the rash typically resolve themselves within one two weeks. However, although an individual bite or set of bites may heal, if you have not eradicated the problem through pest extermination, then you may continue to get bitten. As long as there are bedbugs, they will try to get at you.
  2. Pay attention to when the bites occur. Consider, for example, if you notice the bites after waking up when previously you hadn't noticed them. However, this can also be difficult to determine because each person's reaction time can vary significantly. Symptoms that result from the bite can manifest at any point from a couple of hours to more than a week after the bite occurred.
    • Bedbug bites can have a long incubation period. Visible signs of the bite (a red, itchy bump) can appear up to 10 days after you were initially bitten.
  3. Check your home for signs of bedbugs. Start with where you sleep. Bedbugs want to be where people are so they can get the warm blood of humans. A telling sign is red spots on the sheets. These may come from a bedbug that was squashed after feeding, or from the bites left on you when the bug finished feeding on you.[2]
    • Inspect your entire mattress, including the lining and seams. Look for sleeping bedbugs, carcasses, empty skins (their exoskeletons) and feces (this will look like little black spots or smudges). Check your sheets, pillow cases, and pillows as well.
    • It is very difficult to see and catch a living bedbug. They are tiny brownish insects with broad, oval-shaped bodies. are very good at hiding. However, finding a bedbug is the only way to confirm that that is indeed what bit you.[2]
  4. Visit your doctor. You can also see a doctor for diagnosis if you do not find signs of bedbugs in your bed and cannot identify the source of the bites or rash. However, there is a very good chance that your physician will not be able to firmly diagnose that you have been bitten by a bedbug because the symptoms look so similar to those that result from other insect bites and skin conditions. Nevertheless, you may feel comforted by going to see your doctor, who can confirm for you that bedbugs pose little physical threat to humans.
    • Your doctor may prescribe a topical corticosteroid ointment to help relieve itching and inflammation. These ointments are stronger than the ones you can buy over the counter.
  5. Call an exterminator. This is the surest way to confirm that you have been bitten by a bedbug. An exterminator will search your home and be able to confirm whether or not you have an infestation on your hands.
    • An exterminator will know what to look for and can also then treat your home to remove the bedbugs and prevent future bites from occurring.
    • Home foggers and and bug sprays will not usually kill a bedbug infestation.[3] To make sure you eradicate bedbugs from your home, go with a professional exterminator.

Treating Bedbug Bites

  1. Wash the bites with soap and water. Wash the area with mild soap and water; use a bar of soap and enough water to wet surface of your hands. Work the soap in your hands into thick, soapy lather. Rub the lather over the affected area liberally. Repeat until the entire area is covered. Leave on and do not rinse. Allow the soap lather to dry over the bitten areas. You should experience immediate relief from itching.[2]
    • Washing the bites with soapy water can help alleviate itchiness and prevent a skin infection.
  2. Use home remedies to relieve itching. You can try a number of the following remedies to relieve the itching associated with the bites. These all use products you probably already have on hand.
    • Make a paste of baking soda and water. Slowly add small amounts of water to the baking soda and stir until you have a thick paste. Apply a thick coat of the paste to your bedbug bites. Allow the paste to dry and stay on the rash for an hour or more before washing it off with warm water.
    • Saturate a cotton ball with lemon juice, St. John's Wort or witch hazel, all of which are natural astringents. Dab at the rash with the cotton ball to help dry it out and control the itch.
    • Apply the gel from an aloe plant to bedbug bites. Use pure 100% aloe vera gel. Aloe contains both antibiotic and anti-fungal properties, which can help prevent against a secondary infection due to scratching.
  3. Apply a steroidal anti-itch over-the-counter (OTC) cream. A cream that contains hydrocortisone or cortisone, such as Cortaid, can reduce inflammation and itching. You can buy a 1% hydrocortisone cream from any drugstore or pharmacy. Your doctor can tell you which cream and brand is ideal for you.[2]
    • Follow the package's directions to apply the cream correctly. The cream is very mild and does not cause side effects if used for a short period of time, like a week.
    • You can also get a stronger corticosteroid cream with a doctor's prescription.
  4. Use calamine lotion. When applied to the bites, calamine lotion may provide some symptomatic relief from the itching. It will also help to dry the rash and protect the skin as it heals.[4][5]
  5. Take oral antihistamine. Oral antihistamines, such as diphenhydramine (Benadryl), can help control the allergic reaction (the swelling and rash) associated with the bites.[6]
    • Follow package instructions for proper dosages.
    • Be aware that Benadryl can cause drowsiness and you should avoid driving while taking it.
    • You could also try an OTC antihistamine cream that you apply topically to the affected area.
  6. Get pain relief. If the bites are causing you any discomfort or pain, you can take OTC anti-inflammatory analgesic oral medication, such as ibuprofen, naproxen, or aspirin. Discuss these options with your doctor if you have any doubt about their usage and whether these medications are right for you.[7]
    • Ibuprofen (Advil) is a non-steroidal anti-inflammatory drug (NSAID). It works by reducing hormones that cause inflammation and pain in the body. It also reduces hormones that trigger fever.
    • Aspirin (Acetylsalicylic Acid)is a drug that works as an analgesic, relieving pain by inhibiting pain signals in the brain. It is also an antipyretic, a drug that reduces fever. Do not give to children, however.
    • Acetaminophen (Tylenol) is safer than aspirin for children and has many of the same effects as aspirin. It is not a NSAID, however, and will not reduce inflammation.
  7. Consult your physician. See your doctor if your bite does not clear up within the natural course of a bedbug bite (one to two weeks). You should also see a doctor for treatment if you have any of the following:[3]
    • Multiple bites
    • Blisters
    • Signs of skin infection (tenderness or oozing discharge)
    • An allergic skin reaction (reddened, swollen skin or hives).
    • Bedbug bites, like all insect bites, can become infected through excessive scratching, as underneath the fingernails lies a host of bacterial pathogens. If your bites become infected, they will appear red and swollen, feel tender and may drain pus. Typically there will not be a fever unless a substantial area of the skin is involved. If you experience any of these symptoms, you must seek medical attention as it points to a secondary infection. Your physician may prescribe antibiotic therapy or, if the infection is mild, an antiseptic medication that you can buy without a prescription.[2][8][9]
    • If you experience a severe allergic reaction, your doctor may want to give you an injection of an antihistamine, corticosteroid, or epinephrine (adrenaline).[2][10]

Tips

  • Note that medical treatment is typically not needed for bedbug bites.[10] From a strictly medical perspective, bedbugs pose little, if any, threat to humans. Moreover, there is no evidence to suggest that any treatments will decrease the natural course of the bites (one to weeks), as there has been no research done in this regard.
  • If you see bedbugs during a vacation, especially to a more tropical climate, make sure to clean all your clothes in the hottest water possible before returning home. This will help keep you from bringing bedbugs into your home.

Warnings

  • You can treat existing bites, although they typically run their course within a week or two. However, if you have not treated the infestation, you will continue to be bitten.[2]
