Ammonia Kills Slugs



One of the most common household materials that can be used against slugs in the garden is ammonia.

Ammonia kills slugs on contact and provides nitrogen to plants.

Gardeners use varying ratios of ammonia to water. When spraying the mixture directly onto the slugs the concentration of ammonia can be higher in the range of 3:1, 4:1 or 5:1. But when spraying plants so that the slugs come into contact with the solution on the plants use a lower ratio of 8:1 or even 10:1 so plants won't be burned.

Some gardeners have warned against using the ammonia solution directly on potato and zucchini plants. In those cases, use the old tried and true beer traps.
