Thank you for sharing the photo. The insect in the picture is an earwig. Here’s a detailed overview to help you understand what you’re dealing with:

Understanding Earwigs and Their Bites

What Are Earwigs?

Earwigs are small insects characterized by their elongated bodies and distinctive pincers (forceps) at the end of their abdomen, as seen in your photo. They belong to the order Dermaptera. Despite their somewhat intimidating appearance, earwigs are generally harmless to humans.

Are Earwigs Dangerous?

• Bites: Earwigs can pinch with their pincers if handled roughly, but they rarely bite humans. Their pincers are mainly used for defense and mating displays. If your son was pinched, it might cause mild pain, redness, or swelling but usually no serious injury.
• Venom: Earwigs do not possess venom and are not poisonous.
• Health Risks: They are not known to transmit diseases to humans.

Why Are Earwigs Found Indoors?

Earwigs prefer damp, dark environments and can enter homes seeking moisture, especially in basements, bathrooms, or around windows and doors. Your sister-in-law finding them inside her house is not unusual.

What to Do If Bitten or Pinched

• Clean the Area: Wash the bite or pinch site with soap and water.
• Apply Ice: Use a cold compress to reduce swelling or pain.
• Monitor: Watch for signs of infection like increasing redness, warmth, swelling, or pus.
• Seek Medical Attention: If your son experiences severe pain, allergic reactions (such as difficulty breathing or swelling beyond the bite area), or signs of infection, consult a healthcare provider promptly.

Preventing Earwigs Indoors

• Reduce Moisture: Fix leaks and improve ventilation to eliminate damp environments.
• Seal Entry Points: Use caulk around windows, doors, and other gaps.
• Remove Debris: Clear away mulch, leaves, and other organic material near the foundation.
• Use Traps: Sticky traps or rolled-up damp newspaper can attract and capture earwigs for removal.

Summary

Earwigs, despite their scary pincers, are mostly harmless and unlikely to cause serious harm. The bite or pinch your son experienced is probably mild. However, it’s always best to clean the area carefully and watch for any signs of infection or allergic reaction. Keeping your home dry and sealing entry points will reduce earwig presence indoors.
