How to Get Rid of Snails on Cosmos Plant

Updated: October 30, 2022

Cosmos plants are beautiful and easy to grow, but they can be a magnet for snails. These slimy pests can quickly damage your plants by munching on leaves and flowers, leaving unsightly holes and trails behind. Luckily, there are several ways to get rid of snails on cosmos plants without harming the environment or other beneficial insects.

Identify the Problem

Before you start treating your cosmos plant for snails, it’s important to make sure that you’re dealing with the right pest. Snails are usually easy to spot; they leave a trail of slime behind them as they move and can often be found hiding in damp, shady areas.

Other signs that your cosmos plant has a snail problem include:

  • Holes in leaves or flowers
  • Ragged edges on leaves
  • Bite marks on stem or fruit
  • Shiny trails on leaves or petals

Natural Remedies

There are several natural remedies you can try to get rid of snails on cosmos plants. These methods are safe for the environment and won’t harm other beneficial insects like bees or ladybugs.

Handpicking

One of the easiest ways to get rid of snails is to pick them off your cosmos plant by hand. This method is time-consuming but effective, especially if you only have a few snails to deal with.

To handpick snails, simply go out to your garden at night when the snails are active and start searching for them. Use a flashlight if necessary to help you spot them. Once you find a snail, pick it up and drop it into a bucket of soapy water. This will drown the snail and prevent it from coming back.

Copper Tape

Copper tape is a popular method for repelling snails and slugs. The copper reacts with the slime that these pests produce, creating an unpleasant sensation that repels them.

To use copper tape on your cosmos plant, simply wrap a band of copper tape around the stem or pot. This will prevent snails from crawling up and reaching the leaves and flowers. Copper tape is also a great option for potted cosmos plants.

Egg Shells

Eggshells are another natural remedy that can help keep snails away from your cosmos plants. Crushed eggshells create sharp edges that snails don’t like to crawl over.

To use eggshells, simply crush them up and sprinkle them around the base of your cosmos plant. This will create a barrier that snails won’t want to cross.

Chemical Treatments

If natural remedies aren’t cutting it, you may need to resort to chemical treatments to get rid of snails on your cosmos plant. However, it’s important to choose products that are safe for the environment and won’t harm other beneficial insects.

Iron Phosphate Baits

Iron phosphate baits are a safe and effective way to get rid of snails on your cosmos plant. These baits contain iron phosphate, which is toxic to snails but not harmful to other animals or plants.

To use iron phosphate baits, simply sprinkle them around the base of your cosmos plant. The snails will be attracted to the bait and eat it, causing them to die.

Diatomaceous Earth

Diatomaceous earth is a natural product made from the fossilized remains of tiny aquatic organisms. It’s abrasive and can cut through the soft bodies of snails and slugs, killing them.

To use diatomaceous earth on your cosmos plant, simply sprinkle it around the base of the plant. You can also dust it on the leaves if you see snails crawling on them. Be sure to wear gloves when handling diatomaceous earth as it can be irritating to skin.
