If you’re a gardening enthusiast, you know the pain of dealing with slugs. These slimy creatures can wreak havoc on your plants, leaving behind unsightly holes and damage. If you have a catmint plant in your garden, you may have noticed that it is particularly susceptible to slug damage. Fortunately, there are several ways to get rid of slugs and keep your catmint plant healthy and thriving.

Identify Slug Damage

Before you can take steps to get rid of slugs, it’s important to identify the damage they cause. Slug damage on catmint plants typically appears as irregular holes in the leaves. The edges of the holes may be ragged or smooth, depending on how the slug fed. You may also notice slime trails on the leaves or stems of the plant.

Natural Methods to Get Rid of Slugs

If you prefer to use natural methods to get rid of slugs, there are several options available. Here are some effective methods:


The most straightforward way to control slugs is by handpicking them off your plants. This can be time-consuming but is an effective method for small gardens. Simply go out at night with a flashlight and pick off any slugs you see.

Beer Traps

Slugs are attracted to the smell of beer, making beer traps an effective method for getting rid of them. To make a beer trap, fill a shallow container with beer and place it near your catmint plant. The slugs will crawl in and drown in the beer.

Copper Tape

Copper tape placed around the base of your catmint plant acts as a barrier that slugs won’t cross. The copper reacts with their slime, giving them a mild electric shock that repels them.

Diatomaceous Earth

Diatomaceous earth is a powder made from fossilized diatoms that can be sprinkled around your catmint plant. The powder is abrasive and dehydrates the slug, killing it.

Chemical Methods to Get Rid of Slugs

If natural methods don’t work, you may need to resort to chemical methods. Here are some effective chemical methods:

Slug Pellets

Slug pellets are a common way to control slugs. They contain a poison that kills the slug when ingested.

Slug Bait

Slug bait contains a substance that is attractive to slugs. When they eat it, they die. Be sure to follow the instructions carefully when using slug bait.

Preventing Slug Damage

Preventing slug damage is often easier than getting rid of them once they’ve infested your garden. Here are some preventative measures you can take:

Water in the Morning

Slugs are most active at night and prefer moist conditions. Watering your catmint plant in the morning allows the leaves to dry out during the day, making them less attractive to slugs.

Mulch with Gravel

Mulching with gravel or crushed eggshells creates a barrier that slugs won’t cross.

Plant Slug-Resistant Varieties

Some varieties of catmint are more resistant to slug damage than others. If you’re having trouble with slugs, consider planting a variety that is known to be resistant.


What other plants are susceptible to slug damage?

Slugs will feed on a wide variety of plants, including hostas, lettuce, and strawberries.

What should I do if I see a slug on my catmint plant?

If you see a slug on your catmint plant, pick it off and dispose of it by placing it in a bucket of soapy water or crushing it.

Is it safe to use chemical methods to get rid of slugs?

Chemical methods should be used with caution and according to the instructions on the package. Be sure to keep children and pets away from treated areas.
