How To Get Rid Of Earthworms In Yard

Earthworms are great for the soil, but too much of these burrowing creatures could cause problems in your yard. Earthworms provide aeration and help break down organic matter in the soil. However, they could also make unsightly worm casts and can attract moles and birds that feed on them. Here are some tips on how to get rid of earthworms in your yard.

1. Control Moisture

Earthworms thrive in moist soil, so keeping your yard dry could help prevent an infestation. Make sure to water the lawn deeply but infrequently instead of frequent but shallow watering. The deeper watering can reach the roots and moisture is kept underground, where earthworms can’t access it. Avoid over-watering the yard and make sure to have good soil drainage to keep the yard dry.

2. Improve Soil Quality

Earthworms are attracted to soil that has lots of organic matter since they feed on it. If you want to decrease the number of earthworms in your yard, you can decrease the amount of organic matter in the soil. This could be done by removing any plant debris from the yard, keeping the grass short, and not fertilizing the lawn too much.

3. Using Chemicals

Using chemicals to kill earthworms is not recommended as it can be harmful to the environment and can also harm beneficial organisms in the earth. However, if you still want to use chemicals you can use a pesticide labeled for earthworm control. Be sure to follow the instructions and use it only as a last resort.
