How to Identify a Bed Bug or Mosquito Bite and Prevent Future Bites

Distinguishing Bed Bug Bites from Mosquito Bites

Getting bitten by insects is an unfortunate but common occurrence, especially during warmer weather. Two of the most troublesome creatures that feast on human blood are bed bugs and mosquitoes. The bites from these insects can look similar at first glance, but there are distinguishing characteristics that can help identify which pest snacked on you.

Appearance of Bites

Examining the bites closely is key to determining whether you were a midnight snack for a bed bug or mosquito. Heres what to look for:

Bed Bug Bites:

• Small, red, swollen bumps, like a rash
• Often appear in a line or clustered together
• May look scratched due to excessive itching
• Generally painless initially, but very itchy later

Mosquito Bites:

• Round, red, slightly raised bumps
• Usually appear one bite at a time
• Often itchy, painful, irritating, or cause stinging sensation
• Swell around the bite for about a day

Bite Patterns and Locations

Another clue is looking at the pattern and placement of the bites on your body. Keep in mind:

Bed Bug Bites:

• Usually concentrated on exposed skin, often your face, neck, arms and hands
• Pattern can appear randomized on multiple areas

Mosquito Bites:

• More commonly concentrated on feet, ankles and legs
• Generally just one or two bites in an area

Where Were You When Bitten?

Recalling the setting where you were bitten also aids identification:

Bed Bug Bites:

• Indoors, especially where people sleep or rest, like beds, couches or chairs
• Can be in hotels, motels, shelters, apartments, dorms and houses

Mosquito Bites:

• Outdoors near standing water sources like ponds or puddles
• Areas without screens like porches or patios
• Early morning, dusk and at night

Timeline of Bites and Symptoms

The timing of when bites first appear and how long symptoms persist provides more clues:

Bed Bug Bites:

• May take up to 14 days for bite marks to appear
• Itchiness can last a week or longer
• Bites may continue appearing, indicating ongoing exposure

Mosquito Bites:

• Start itching immediately or within a few minutes
• Itching typically resolves within a few days
• One-time occurrence

Treating Bites

Once properly identified, bed bug bites and mosquito bites can be treated at home to ease symptoms:

Soothing Bed Bug Bites

• Apply hydrocortisone cream, calamine lotion, baking soda paste or oatmeal bath to reduce itching and inflammation
• Take an oral antihistamine containing diphenhydramine (Benadryl) to relieve itchiness
• Apply ice pack to bite areas to ease swelling
• Avoid scratching as it can cause infection

Relieving Mosquito Bites

• Use antibacterial soap and water to clean any broken skin from scratching
• Apply a paste of baking soda and water to reduce swelling and itching
• Take an over-the-counter oral antihistamine for itch relief
• Apply hydrocortisone cream to lessen inflammation

See your doctor if bites become infected, very swollen, or you have an extreme reaction. They can provide prescription strength topical or oral medications as needed for symptom relief.

Preventing Future Bites

While treatments can help manage bite symptoms after the fact, taking proactive measures can help prevent bed bugs and mosquitoes from making you a snack in the first place:

Avoiding Bed Bugs

• Inspect rental furniture, hotel rooms and used items carefully before bringing them home
• Install bed encasements to trap bed bugs and make detection easier
• Apply diatomaceous earth powder around beds, furniture and baseboards
• Wash and dry bedding and clothing on the hottest setting items can stand
• Vacuum frequently focusing on cracks, crevices and seams

Deterring Mosquitoes

• Apply an EPA registered insect repellent when spending time outdoors
• Wear light colored long sleeved shirts and long pants outside
• Keep screens in good repair and close when windows are open
• Eliminate sources of standing water in your yard after it rains
• Use citronella candles and torches when sitting on your patio or deck

With some diligence to bite prevention and properly identifying whether bed bugs or mosquitoes are the culprits behind your itchy misery, you'll be better equipped to keep these pests from making you their next meal.
