Salt as a Method for Controlling Earwigs: Does It Work or Is It Just Salty Science?

When battling earwigs, people will try almost anything—from essential oils to coffee grounds to midnight bug hunts. But what about something as simple as salt? Can this kitchen staple double as an effective earwig assassin?

🧂 The Short Answer:

Yes, salt can kill earwigs—but it’s not the most effective or practical method for long-term control.
Think of it like using a squirt gun to put out a house fire. It works… technically, but there are better tools for the job.

🧪 How Does Salt Kill Earwigs?

Salt works through a process called osmosis (fancy science word alert). Here’s the breakdown:

  1. Salt dehydrates: When sprinkled directly on an earwig, salt draws moisture out of its body.
  2. Desiccation: This extreme dehydration damages the bug’s internal systems, eventually leading to its demise.
  3. It’s fast… if you hit your target: Salt acts quickly, but only if you apply it directly to the earwig.

It’s like the insect version of being stranded in the desert without water. Not exactly a fun day for the earwig.

🚫 Why Salt Isn’t the Best Earwig Control Method

While salt can technically kill earwigs, here’s why you might want to skip this DIY hack:

  • Requires direct contact: You have to see the earwig, aim, and sprinkle. Good luck with that—they’re nocturnal and hide like pros.
  • Messy aftermath: Salt can damage plants, stain surfaces, and mess with soil health by altering pH levels.
  • Short-term solution: Even if you salt one earwig to oblivion, there are probably 20 more lurking nearby.

It’s like fighting a zombie horde with a salt shaker—satisfying at first, but not sustainable.

✅ What Works Better Than Salt?

For long-term control, try these proven methods:

  • Diatomaceous Earth: A natural powder that dehydrates bugs without harming your garden.
  • Traps: Rolled-up damp newspaper makes an irresistible earwig trap—way less messy than salt.
  • Moisture Control: Fix leaks, reduce mulch buildup, and eliminate damp hiding spots.
  • Essential Oils: Strong scents like peppermint or eucalyptus can repel earwigs naturally.

🤔 But What About Using Salt in the Garden?

Bad idea. Salt can:

  • Damage plant roots
  • Alter soil chemistry (leading to nutrient deficiencies)
  • Harm beneficial insects that you actually want in your garden

Unless you’re looking to create a barren wasteland where nothing grows, keep the salt in the kitchen.

🚀 The Bottom Line

  • Can salt kill earwigs? Yes, but only if you sprinkle it directly on them.
  • Is it an effective pest control method? Not really. It’s messy, inefficient, and bad for plants.
  • Should you try it? Only if you’re feeling dramatic—or if it’s the only thing within arm’s reach.
