Ammonia for Garden Pest Management and Slugs

Ammonia is a versatile and non-toxic solution for managing garden pests, including slugs.

Ammonia can be used to repel slugs, as they are highly sensitive to its fumes.

To use ammonia for slug control, mix 1 part ammonia with 9 parts water in a spray bottle and spray it around affected areas at night when slugs are most active.

This solution can be used in place of commercial slug baits, which often contain toxic chemicals.

Ammonia is a simple and effective solution for controlling garden pests like aphids and slugs. It's readily available in most pharmacies and is relatively inexpensive.

The concentration of ammonia needed to kill aphids on currants is 10%, which is sold in pharmacies. This concentration is enough to get rid of the pest.

Ammonia works quickly on aphids, causing dysfunction in their digestive tract and disrupting their respiratory function. The insect's body responds with a burn in the gastrointestinal tract, swelling of the mucous membrane, convulsions, and finally, paralysis.

For slugs, a 1:4 concentration of ammonia is effective, and death is instantaneous. However, be careful not to inhale the fumes, as they can be hazardous to your health.

Ammonia is also toxic to slug eggs, which can be a concern for gardeners who want to protect their plants. However, it's worth noting that there are natural alternatives like spinosad, which is a bacterium that can be toxic to certain garden pests.

Here are some key facts about using ammonia for garden pests:

Overall, ammonia is a simple and effective solution for controlling garden pests like aphids and slugs. However, it's essential to use caution and consider natural alternatives like spinosad to minimize harm to your plants and the environment.

Dropping slugs in a 10% solution of household ammonia is a simple way to deal with them, but it's not the only method. Apparently, soapy water also works.

To spray slugs with ammonia, you'll need to use a direct application method, as government websites with an edu extension warn against spraying plants or soil. This technique is unlikely to work, as ammonia evaporates quickly, leaving no lasting effect.

A quick test of spreading household ammonia on a hosta leaf showed that the smell was strong for only about 3 minutes, and nothing remained after evaporation. This means it can't prevent slugs from crossing the ground or traveling on plants.

If you do choose to use ammonia, be aware that it can burn your nose, as one commenter mentioned. A concentration of around 1:4 is suggested for a bucket to collect slugs, resulting in instantaneous death.

Some people have tried using diluted ammonia to kill slug eggs, but this method is not without concerns. One commenter wondered if it might harm slug predators or their eggs.

A safer and more effective option for controlling slugs is using a product containing spinosad, a naturally occurring bacterium that can be toxic to certain garden pests. This is certified for use in organic agriculture and has been shown to work well on plants like hostas and dahlias.
