Most insect bites and stings cause mild, localized reactions that resolve within a few days. Some signs may indicate a more severe issue that should be checked by a doctor.

Call your doctor if you have:
1. Signs of Infection
• Redness, warmth, or swelling at the bite location that’s spreading
• Pus or drainage from the bite
• Fever or chills
These are indicators of a skin infection such as cellulitis.

2. Severe Allergic Reactions (Anaphylaxis)
Difficulty in breathing or swallowing
Swelling of the face, lips, or throat
Fast heart rate, dizziness, or fainting
These require immediate emergency care.

3. Systemic Symptoms

Headache, fever, joint pain, rash, or tiredness a few days following a bite, especially by ticks or mosquitoes, could be an indicator of a vector-borne illness such as Lyme disease, West Nile virus, or other arboviral illnesses.

4. Venomous Bites or Stings

Suspected spider (e.g., black widow, brown recluse) or insect bites or stings (e.g., some wasps or hornets) from suspected venomous spiders or insects must be assessed early because of potential tissue damage or systemic consequences.

5. Atypical or Prolonged Skin Reactions

If the affected area becomes increasingly worse, develops ulcers, or fails to change within 7–10 days, see a medical provider to eliminate complications or allergic reactions.

Medical Advice

If in doubt, it’s always best to consult a health professional—especially if you have pre-existing health conditions, a weakened immune system, or a history of anaphylactic episodes.
Your well-being matters. Warning signs identified early can prevent complications.
