If permethrin doesn’t seem to work, don’t panic—there are several reasons this can happen, and effective alternatives are available.

In many cases, it’s not true treatment failure, but rather application issues, reinfection, or normal post-treatment symptoms.

🧠 Step 1: Make Sure It’s Actually Treatment Failure

✔ Normal After Treatment (Not Failure)

Itching for 2–4 weeks

Skin irritation or rash lingering

Gradual improvement over time

👉 This is your body reacting—not live mites

❌ Signs of Possible Failure

New burrows appearing after 2 weeks

Rash spreading to new areas

No improvement after 4 weeks

Symptoms getting worse

⚠️ Step 2: Common Reasons Permethrin Doesn’t Work

1. Improper Application (Most Common)

Missing areas of the body

Not using enough product

Washing off too early

Skipping hands, feet, or fingernails

2. Reinfection

Untreated household members

Contaminated bedding or clothing

Surfaces not cleaned

3. Eggs Hatch After Treatment

Eggs may survive the first treatment

Hatch within a few days

Require a second treatment

4. Possible Resistance

Some mites may not respond fully

More likely after repeated treatments

🔄 Step 3: What to Do Next

✔ Reevaluate Your First Treatment

Did you cover your entire body?

Did you leave it on long enough?

Did everyone in your household receive treatment at the same time?

✔ Ensure Environmental Cleaning

Wash bedding and clothing

Use hot water and high heat

Treat furniture and surfaces

🌿 Step 4: Consider Alternative or Supportive Treatment
