What is bug bites?
Bug bites — mosquitoes, fleas, gnats, midges, ticks — cause localized allergic reactions: red itchy bumps. Most resolve on their own. Some carry disease risk (ticks: Lyme; mosquitoes: West Nile etc.).
Severe allergic reactions, infected bites, or signs of disease transmission warrant evaluation.
Do I have bug bites? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
Direct skin contact with biting insect. Reaction is allergic to insect saliva.
Is it contagious?
No directly — but some insects transmit infections (Lyme, West Nile, malaria, dengue, Zika).
The bullseye rash from tick bites is iconic — but only about 70% of Lyme cases have it. Tick bite with any unusual rash warrants attention.
Can it be treated online?
Routine bug bites are well-suited to telehealth. Tick bites with concern for Lyme, severe allergic reactions, infected bites, suspected disseminated infection — need in-person evaluation.
How bug bites is treated
Topical hydrocortisone for itch. Oral antihistamines for multiple bites or itch. Antibiotics for infected bites or as Lyme prophylaxis after tick bite. Tick removal: fine-tipped tweezers, grasp at skin level, pull straight up. Save the tick for ID if Lyme concern.

- Tick prevention on pets
How long does it last?
Most bites resolve in days. Some reactions take 1–2 weeks.
