Do Slugs Eat Grass?

If you are having issues growing a perfect lawn, you may be wondering whether any pests are to blame for bare patches or limited growth in certain areas. Slugs are a common pest that are thought of by many when they think of plants being eaten in their garden. So, do slugs eat grass?

The answer is not a definitive yes or no. While slugs are known to eat many types of plants, fully grown grass is not typically on the menu. However, young grass seedlings or sprouts are a different story. Slugs will often go for these smaller, more vulnerable plants in search of an easy meal.

This may be the cause of issues in your lawn if younger grass seedlings are not given the opportunity to grow because slugs are getting to them early.

Signs of a Slug Infestation

It’s critical to identify the issue you’re dealing with before determining how to handle a slug infestation on your lawn. The following are some of the most frequent signs of a slug problem:

  • Holes in leaves appear overnight
  • Stems of plants not damaged – only leaves
  • Slug slime on damaged leaves
  • Also, look for lime trails on nearby pavement or paths

It’s important to remember that slug damage is most common after heavy rain or in early spring, but it is possible to experience slug problems any time of the year.

If you want to be 100% sure that slugs are the pests damaging your lawn, try going out at night with a flashlight and shining it on your lawn – you will be sure to catch them if they are the cause as they are not quick at escaping once caught in the act!

Are Slugs Bad For Your Grass?

Slugs are not necessarily bad for your grass, but they can cause some problems. First, as mentioned earlier, slugs will sometimes eat young grass seedlings before they have a chance to grow. This can stunt the growth of your lawn and make it more difficult to achieve a lush, green look.

If you are trying to overseed areas of your lawn or repair some patchy areas with seed, this may be a particular issue for you. You may want to consider using slug traps or baits to keep these pests at bay until the seed has had a chance to germinate and grow into strong grass plants.

In addition, slugs often leave behind slime trails as they move around your lawn. This can make the grass wet and inviting for other pests, like ants and mosquitoes. If you have a slug problem, it’s important to take care of it quickly to prevent further damage to your lawn.

How to Stop Slugs From Eating Grass

If you are sure that slugs are the culprit in damaging your lawn, don’t worry – there are several ways you can act to keep them at bay, some simple and cheap to implement.

Firstly, let’s try some methods to make your lawn less appealing to slugs:

Encourage Natural Predators

There are several predators that like to snack on slugs, so try to encourage them to hang around your garden. Toads, ground beetles, and hedgehogs will all eat slugs, so try to create a habitat that is inviting to them. This may include leaving some areas of your lawn a little wilder with longer grass or building a small hedgehog house.

Remove Their Hiding Places

Slugs like to hide in damp, dark places during the day, so try to remove any potential hiding spots from your lawn. This may include removing piles of leaves, logs, or debris. Slugs will also congregate under pots or other garden objects, so make sure to move these regularly.

Make Your Lawn Less Moist

Slugs are attracted to moisture, so try to make your lawn less inviting by reducing the amount of moisture it holds. This may include aerating your lawn more frequently or making sure that any irrigation systems you have are not overwatering the grass.

If you have problems with puddles forming on your lawn, you may want to consider fixing any drainage issues.

Strategic Planting

There are some plants that slugs don’t like to eat, so try to incorporate these into your landscaping. Plants with sharp leaves, such as raspberries or roses, are less attractive to slugs. You can also try planting herbs, such as sage or rosemary, around the perimeter of your lawn as a natural deterrent.

Use Barriers & Difficult Terrains

If you have particularly vulnerable plants or areas of your lawn that seem to be more attractive to slugs, you may want to try using barriers. This may include placing coffee grounds, eggshells, or sand around the base of plants. Gravel or stones are also a good option for creating a barrier as slugs do not like to cross them.

Copper tape can be a highly effective barrier as well, and you can find this at most hardware stores or online. Simply place the tape around the perimeter of pots or garden beds – the slugs will receive a mild shock when they try to cross it, which will deter them.

If the deterrents above are too late and your lawn is overrun with slugs, you may need to put a plan in place to catch and kill these pests;

Pick Up Slugs By Hand

This may seem like a tedious task, but it can be effective if you have a small number of slugs. Simply put on some gloves and go out to your lawn at night with a flashlight. Look for the slimy trails that slugs leave behind and pick them up by hand, dropping them into a bucket of soapy water.

Use a Slug Beer Trap

Slug traps are a more effective way to catch large numbers of slugs at once. There are several different types of slug traps available, but one of the most popular is the beer trap. Simply bury a container, such as a yogurt cup, in your lawn so that the rim is level with the ground. Fill the container with beer and wait for the slugs to crawl in. Check the trap regularly and dispose of the slugs as needed.

Put Down Slug Pellets

If you have a severe slug problem, you may need to resort to using slug pellets. These are available at most hardware stores or online and can be effective in killing large numbers of slugs.

However, slug pellets can also be harmful to pets and children, so be sure to use them carefully and follow the instructions on the package.

Use Salt To Kill Slugs

This is the cheapest and most effective way to kill slugs quickly but not recommended because it’s an extremely cruel way to get rid of slugs. Salt basically sucks all the water out of the slug’s body, causing it to shrivel up and die.

The use of salt in your garden could also lead to other problems, such as the soil becoming too salty for plants to grow.


Slugs can become a big issue if you have a young lawn or if you live in an area with a lot of moisture. There are several things you can do to deter slugs, such as making your lawn less inviting or planting certain types of plants.

If you have a serious slug problem, you may need to resort to more extreme measures, such as traps or slug pellets. There are a number of ways to get rid of slugs in your lawn without resorting to chemicals or other harmful methods such as salt. By taking some simple precautions, you can make your lawn less attractive to these pests and keep them under control.
