Jellyfish Stings at Delaware Beaches: What to Do, What to Pack & How to Get Relief Fast

If you’ve spent any time at the Delaware beaches this summer, you’ve likely noticed: jellyfish are out in full force. Whether you’re sunbathing in Rehoboth, wading in Dewey, or building sandcastles in Bethany, there’s a good chance someone nearby has had a run-in with one of these gelatinous creatures.

So, what can you do about it? Be prepared.
Here’s your beach-ready guide for spotting, treating, and surviving jellyfish stings—without letting them ruin your day.

🛑 First: Don’t Panic — But Act Fast

Jellyfish stings vary in intensity. Some feel like a mosquito bite; others can deliver a serious zap. The sting comes from tiny, venom-filled barbs called nematocysts. Quick and proper treatment makes a world of difference.

⚠️ What to Do Immediately After a Sting

1. Get out of the water – Do so calmly. Avoid splashing or panicking.

2. Avoid freshwater rinses – Freshwater can cause the nematocysts to release more venom. Instead:

3. Rinse with vinegar or saltwater – A 50/50 vinegar and water mix is best.

4. Remove tentacles – Use tweezers or the edge of a credit card to scrape them off gently.

5. Apply a cold compress – Wrap ice in a towel or use a chilled bottle to soothe swelling and pain.

🧴 Delaware beach lifeguards now carry diluted vinegar as a first line of defense against jellyfish stings—especially in Rehoboth and Bethany.

🏠 Home Remedies & OTC Relief

Once you’ve handled the basics, tackle the lingering irritation. Here are top options:

• Hydrocortisone cream – Calms inflammation and itching.

• Ibuprofen or acetaminophen – Reduces pain and swelling.

• Aloe vera or “Lana Kane” spray – Soothes and cools the sting.

• Baking soda baths – Especially helpful for sea lice (jellyfish larvae).

• Benadryl or other antihistamines – Helps with allergic reactions or rash.

🧼 Dewey Beach lifeguards have also been using shaving cream for sea lice. The verdict is still out, but some swear by it for easing irritation.

🧳 What to Pack in Your Beach Bag

Jellyfish aren’t going away anytime soon—but your discomfort can be. Pack this jellyfish first-aid kit before your next beach day:

• Spray bottle with diluted vinegar

• Hydrocortisone cream

• Aloe spray or Lana Kane

• Shaving cream (especially for kids)

• Benadryl or chewable antihistamines

• Tweezers or credit card

• Ibuprofen

• Small towel + ziplock (for makeshift cold pack)

🚿 Bonus Tip: Rinse Off Immediately

Once you’re out of the water, do a quick saltwater rinse and get out of your swimsuit. Jellyfish larvae can cling to skin and fabric, causing itchy rashes later (a.k.a. “sea lice”). A fast rinse and wardrobe change can save you a lot of scratching.

🌊 Final Word

You can’t avoid jellyfish—but you can outsmart them.
This summer’s jellyfish bloom is strong, but a little prep can keep the sting away from your fun. Keep your kit handy in the car, beach wagon, or tote—and remember the vinegar.

Stay safe, stay salty, and don’t forget the vinegar.
