A Guide to Identifying and Treating Common Bug Bites

Spending time outdoors in the warmer months means enjoying fresh air and sunshine. But it also exposes us to annoying and sometimes dangerous bug bites. Mosquitoes, bees, spiders, bed bugs and other insects can inflict irritating and painful bites.

Learning to identify and treat different types of bug bites is important for getting relief and avoiding complications. This guide covers how to recognize common bug bites based on appearance, symptoms and location on your body. Well also explore the best treatment options for addressing itch, swelling and preventing infection.

Mosquito Bites

Mosquitos pierce the skin with their proboscis mouthpart and inject saliva that contains proteins causing itchy irritation. Reactions can vary from small red bumps to significant swelling and rashes:

• Appearance - Round, puffy white and red bumps. A hard, raised central welt may be visible.
• Size - Typically 1/4 to 1/2 inch in diameter.
• Sensation - Itchy, burning, stinging.
• Number - One bite or clustered groupings of multiple bites.
• Location - Commonly on feet, ankles, legs, arms and hands.

Mosquito bites are notoriously itchy, causing the urge to excessively scratch. Over-scratching further irritates the skin and can lead to infection. The swelling may persist for a few days up to a week.

Bed Bug Bites

Bed bugs feed on blood, most often biting exposed skin at nighttime:

• Appearance - Small, flat or slightly raised red bumps, like a rash. They may become inflamed and itchy.
• Size - 1mm to 5mm, similar to a pen tip.
• Sensation - Itchy, some people may not react at all.
• Number - Multiple clustered bites, often in a zigzag formation along the body.
• Location - Face, neck, arms, torso and legs. Areas exposed while sleeping.

Bed bug bites usually resolve within 1-2 weeks. Scratching may cause them to become infected. Consult an exterminator if you suspect an infestation in your living space.

Spider Bites

Venom from a spider bite causes a range of effects from mild irritation to severe reactions:

• Appearance - Pinpoint marks or raised, white bump with red ring around it.
• Size - Relatively small, between a pinhead to marble size.
• Sensation - Mild stinging, itching, throbbing pain or cramping at bite site.
• Number - Usually just one bite mark, unless multiple spiders are present.
• Location - Arms, legs, torso, neck. Wherever spider contacted skin.

Spider bites can progress into blisters or ulcerated sores. Seek medical treatment for severe swelling, fever, dizziness or other worrisome symptoms.

Tick Bites

Ticks latch onto skin and feed on blood. Their bites often go unnoticed until after the tick falls off:

• Appearance - Small red bump or mild rash, maybe a small hole where tick was embedded.
• Size - Fairly small, just a few millimeters across.
• Sensation - Mild itchiness, pain, or none at all.
• Number - Usually just one, unless person is exposed to high-tick areas.
• Location - Layer areas like groin, armpits, behind knees or ankles.

Tick bites pose the risk of transmitting Lyme disease, Rocky Mountain spotted fever and other infections. Check your body closely after potential tick exposure.

Flea Bites

Flea bites produce tiny red spots with a halo ring and centralized red dot:

• Appearance - Small red bump with a red dot in the middle, may look like a target.
• Size - 1 to 3 mm in diameter.
• Sensation - Itchy, stinging or burning irritation.
• Number - Groupings of multiple bites, from just a few to dozens.
• Location - Commonly around ankles and legs.

Aggressive scratching of flea bites can damage the skin. Use medicated shampoos and flea control products on pets to eliminate infestations in your home.

Ant Bites and Stings

Ant bites and stings cause raised bumps that may resemble pimples or blisters:

• Appearance - A pustule or blister with possible redness around site.
• Size - Can range in size from 1 to 5 mm.
• Sensation - Burning, itching, throbbing, intense pain.
• Number - Usually just one, but multiple stings are possible.
• Location - Feet, legs and arms most likely as ants crawl on the ground.

Wash ant bites with soap and water to clean them. For severe reactions, use ice packs and OTC antihistamines or hydrocortisone cream.

Bee, Wasp and Hornet Stings

Bees, wasps and hornets inject venom with their stingers causing a painful raised bump:

• Appearance - Central raised welt with red or pink ring around it.
• Size - Up to 1 cm in diameter.
• Sensation - Instant burning pain, lasting soreness.
• Number - Generally just one sting site.
• Location - Extremities, torso, neck and face most likely.

Remove any leftover stinger carefully with a swipe of a credit card. Use a cold pack and OTC pain medication to ease discomfort from the sting.

Chigger Bites

Microscopic chigger mites burrow into the top layer of skin causing itchy welts:

• Appearance - Small red bumps, may have a white/blue dot in center.
• Size - Pinhead sized.
• Sensation - Intensely itchy, prickling, burning.
• Number - Groupings of multiple bumps or cluster.
• Location - Waistline, beltline, or areas where clothing fits tightly.

To ease severe itching and swelling, use topical calamine lotion, hydrocortisone cream or antihistamines. Thoroughly wash and sanitize clothes and bedding to kill any lingering mites.

Mite Bites

Mites produce irritating bumps and blisters on the skin that cause redness and intense itching:

• Appearance - Small dots, bumps or blisters, fluid/puss filled.
• Size - Usually smaller than 1 cm.
• Sensation - Itching, stinging, prickling, crawling sensation.
• Number - May be multiple individual bites.
• Location - Face, hands, body creases or genitals.

Avoid excessive scratching to prevent infection. Check bath towels for mites and launder frequently. Steroid creams and medicated shampoos may offer relief.

Gnat Bites

Small flying gnats often bite exposed skin, creating tiny bumps:

• Appearance - Small red, pink or white bumps.
• Size - Fairly small, just 1 to 2 mm.
• Sensation - Itchy, burning, irritation.
• Number - One to several individual bites.
• Location - Ankles, legs, arms, and other exposed areas.

Avoid scratching gnat bites as this worsens irritation and itchiness. Topical hydrocortisone cream can relieve swelling and inflammation.

Kissing Bug Bites

Also called assassin bugs, kissing bugs feed around the mouth and lips, causing red itchy welts:

• Appearance - Red raised or flat bumps on reddened skin.
• Size - Bites measure about 1 cm across.
• Sensation - Painful, itchy, irritating.
• Number - One large bite or a grouping of multiple bites in one area.

Kissing bug bites can potentially transmit Chagas disease. Seek medical care if you suspect this bug is responsible for bites or welts near your mouth.

Treating Bug Bites

The most common bug bite symptoms include inflammation, swelling, redness, pain, itching and irritation. Here are some top methods for getting relief:

• Wash the bite area gently with soap and water.
