1. Does drinking alcohol kill Ants?

Ethanol is also known as drinking or ethyl alcohol. It gives off a concentrated odor that can repel ants. This can either be sprinkled on them or used to wipe their trails.

It can also be poured into an anthill outdoors to kill and get rid of a whole colony of ants.

3. How does alcohol repel Ants?

Alcohol repels ants in a couple of different ways.

  • Firstly, the strong smell of alcohol disrupts the ant’s communication. Ants rely on scent trails to navigate and communicate with each other. By erasing these scent trails with alcohol, you can disrupt their activities and discourage them from the area. 
  • Secondly, the harsh and pungent smell of alcohol is also physically repelling to ants. The scent is so overpowering that it blocks the tiny breathing holes on their abdomen, causing discomfort and forcing them to retreat.

4. Alcohol for ants on Plants

However, diluted alcohol with less than 5% volume cannot have any negative effects on plants.

Ant eggs are soft and moist and alcohol can kill them by dehydrating and burning into their weak layers.

However, you need to ensure that they are well covered and soaked in alcohol. It takes about 1-2 hours for alcohol to completely destroy ant eggs.

6. Disadvantages Of Using Alcohol 

While alcohol can be an effective ant killer, it also comes with a variety of disadvantages.

  • One of the most significant disadvantages of using alcohol to kill ants is the risk to human health. Alcohol, especially in higher concentrations, gives off strong fumes that can be irritating and harmful if inhaled in large quantities. 
  • Alcohol is also flammable, creating a fire hazard when used in large amounts. 
  • Furthermore, alcohol can harm plants if not used properly. It can dry out plant tissues, causing them to wilt or even die.
  • Lastly, the use of alcohol to kill ants is only a temporary solution. Unless you eliminate the entire colony, including the queen, new ants will likely appear after a short while. 


Is alcohol a safe and natural alternative to chemical ant killers?  

While alcohol is a natural substance, it’s not necessarily safe to use as an ant killer, especially in large quantities or without proper precautions.

It can pose health risks to humans and pets if inhaled, ingested, or comes into contact with the skin, and it’s also harmful to many types of plants.  

Will spraying alcohol around my house keep ants away?
