1. Does Ammonia Kill Roaches?

Yes, ammonia can kill roaches, but only if it’s sprayed on them directly. Ammonia can also repel roaches by adding it to warm water and mopping the floors with it.

However, ammonia is not very effective if you are simply applying it around your home without direct contact with the roaches. You need to mix ammonia with a balanced amount of water and pour it into a spray bottle.

2. How to Use Ammonia To Kill Roaches

To use the ammonia spray against roaches:

  1. Prioritize safety by wearing a mask, gloves, and goggles to shield yourself from potential toxic fumes, regardless of whether you’re using standard household ammonia or the pure form.

  2. Adjust the spray bottle nozzle to the narrow setting, ensuring a concentrated and forceful stream.

  3. Direct the ammonia spray at individual cockroaches consistently until they are thoroughly saturated.

  4. Opt for a quick and efficient cleanup process for any deceased roaches, and dispose of their bodies as far away from your residence as possible.

Pure ammonia poses risks, particularly in enclosed spaces, causing breathing issues and skin irritation, especially at night. Exercise caution and opt for diluted ammonia for safety.

While ammonia is generally safe for laundry, avoid mixing it with stain removers like bleach, as it may lead to harmful reactions. Be cautious with reactive chemicals in detergents, especially on wool or natural silk, as ammonia can be corrosive.

When using ammonia in the washing machine, add it to the drum before clothes and water. Prefer mild, bleach-free detergents. Refrain from washing towels or heavy sweaters with ammonia, as it can damage them.
