Earwigs can eat squash plants, and they’re actually one of those garden pests that can cause real damage if you’re not paying attention.
These little pinch bugs love tender squash leaves and seedlings, especially when the plants are young and vulnerable.
If you’ve been wondering “do earwigs eat squash plants,” the short answer is yes, they do, but the good news is they’re not usually the worst offenders in your garden.
Still, when earwigs eat squash plants in large numbers, they can set your crop back significantly.
The damage they cause often gets confused with other pests, which makes identifying the real culprit tricky.
In this post, we’ll look at whether earwigs eat squash plants, why they do it, and what you can do to protect your garden.
Let’s dig in.
Why Earwigs Eat Squash Plants
Earwigs eat squash plants for a few simple reasons, and once you understand their behavior, managing them gets much easier.
1. Earwigs Are Opportunistic Feeders
Earwigs don’t specifically target squash plants the way some pests do.
They’re omnivores that feed on soft plant tissue, aphids, insect eggs, and decaying matter.
When they come across young squash leaves, they treat them as an easy meal.
This is why earwigs eat squash plants most often when the leaves are soft and new.
2. Young Squash Leaves Are Tender
Squash seedlings and young transplants have thin, tender leaves that earwigs find irresistible.
Earwigs eat squash plants by chewing small irregular holes in the leaves, often near the edges.
If the damage is severe, seedlings can be completely defoliated.
That’s why most trouble with earwigs and squash starts right after planting.
3. Nighttime Feeding Habits
Earwigs are nocturnal, meaning they do most of their feeding after dark.
This is why you might notice damage in the morning but never see the pests themselves.
If you suspect earwigs eat squash plants in your garden, grab a flashlight and check after sunset.
You’ll likely find them hiding in the folds of leaves or tucked into the soil.
4. Moisture and Shelter Attract Them
Earwigs thrive in damp, cool environments, and squash plants create perfect hiding spots.
Mulch, dense foliage, and moist soil all give earwigs the shelter they love.
This is why earwigs eat squash plants more often in gardens with heavy mulch or poor drainage.
Signs Earwigs Are Eating Your Squash Plants
Knowing what earwig damage looks like helps you act before it gets out of hand.
1. Irregular Holes in Leaves
Earwigs eat squash leaves by chewing ragged, irregular holes.
These holes often appear near the leaf edges and can merge into larger damaged areas.
Unlike slug damage, earwig holes tend to be smaller and more scattered.
2. Damage on Seedlings and New Growth
Earwigs eat squash plants most aggressively on new growth.
If your seedlings are getting chewed overnight, earwigs are a likely suspect.
Young plants are especially at risk because they can’t recover as quickly.
3. Pests Hiding During the Day
During the day, earwigs hide in crevices, under mulch, or in the leaf axils of squash plants.
If you shake a leaf over a piece of paper, you might see them scatter.
Finding them in these hiding spots confirms that earwigs eat squash plants in your garden.
How to Stop Earwigs From Eating Squash Plants
The good news is you don’t have to live with earwig damage, and there are several simple ways to protect your crop.
1. Trap Them With Rolled Newspaper
Earwigs love dark, tight spaces, so rolled-up newspaper makes an excellent trap.
Place damp newspaper rolls near your squash plants overnight.
In the morning, shake the earwigs out into a bucket of soapy water.
Repeat this for several nights to reduce the population that eats squash plants.
2. Use Diatomaceous Earth Around Plants
Sprinkle food-grade diatomaceous earth around the base of your squash plants.
This fine powder damages the exoskeleton of earwigs that crawl over it.
Reapply after rain or watering to keep it effective.
It’s a safe option if you’re worried about earwigs eating squash plants but want to avoid harsh chemicals.
3. Reduce Moisture and Mulch
Since earwigs thrive in damp conditions, letting the soil dry slightly between waterings helps.
Thin out heavy mulch around squash plants to remove hiding spots.
Good airflow also makes the environment less inviting for earwigs that eat squash plants.
4. Encourage Natural Predators
Birds, toads, and ground beetles all eat earwigs.
Inviting these predators into your garden helps keep earwig numbers down naturally.
A small birdhouse or a shallow water dish for toads can make a big difference.
5. Handpick at Night
If you only have a few plants, handpicking is one of the most direct methods.
Go out with a flashlight after dark and pick earwigs off your squash plants.
Drop them into soapy water and repeat every few nights until the damage stops.
So, Do Earwigs Eat Squash Plants?
Earwigs do eat squash plants, especially tender seedlings and young leaves.
They’re opportunistic feeders that chew irregular holes and cause the most damage at night.
But with traps, moisture control, and a little nighttime diligence, you can keep earwigs from eating squash plants and protect your harvest.
So don’t panic if you spot a few pinch bugs, just take action early and your squash will bounce back fine.
