In the garden, ants improve soil, spread seeds, and control certain pests. However, they are unwelcome in the house. myHOMEBOOK reveals how a specific home remedy can help against ants.
A small, black trail heading straight for pantry shelves or pet food bowls: This is often how we notice unwanted ant visitors in our homes. Many quickly resort to aggressive chemicals, which are effective but also harmful to the environment. However, there are home remedies that can naturally combat these small insects. In this article, we answer the question of how petroleum jelly can help against ants.

Overview
How Petroleum Jelly Helps Against Ants
Ants are organized in colonies. The queen ant is the head of the colony, and all other ants serve her. They spend the entire day expanding and repairing the nest, caring for the brood, and–most importantly–foraging for food. It is during this foraging that the insects may invade our homes.
Even tiny cracks in masonry, cable ducts, or pipes are enough for them to enter. Usually, individual ants scout ahead, and if they find a food source, they leave scent trails for the other ants in the colony. Once the other ants detect these scent trails, an ant trail can quickly form to and from the food source, ensuring a swift transport of food back to the colony.
This is where petroleum jelly can be an effective remedy against ants. Applying a thin layer of petroleum jelly on the ant trail achieves two things:
- The greasy layer of petroleum jelly covers the scent trails left by the scouting ants, causing the following ants to lose their orientation.
- The greasy, sticky consistency of petroleum jelly causes ants to get stuck or struggle to free themselves, prompting them to retreat.
Benefits of Petroleum Jelly Against Ants
- While chemical ant control products like sprays or powders are toxic to humans and animals, petroleum jelly is completely harmless. This makes it a viable solution, especially in households with children or pets.
- Additionally, most people already have petroleum jelly at home, making it easy to treat a minor ant infestation quickly. And for those who don’t, it can be purchased very cheaply almost anywhere.
- Moreover, the application is simple and requires no precautions or other preparatory measures.

Application of Petroleum Jelly Against Ants
To effectively use petroleum jelly against ants, proper application is key:
- First, locate the entry point of the ants into the house or apartment. This could be leaky window frames, ventilation slots, or pipes. Use a cotton swab to apply a thin layer of petroleum jelly directly in front of the entry hole.
- Then, observe: Are ants still entering the living spaces? If so, there may be another entry point.
- Regularly refresh the areas with fresh petroleum jelly, as it can dry out or become ineffective due to dust after a few days.
When Petroleum Jelly Alone No Longer Helps
Petroleum jelly is particularly effective against ants when the infestation is still minor. In cases of a large ant influx in the house, petroleum jelly may no longer be sufficient. In such instances, chemical solutions may be the only option. Here are some possibilities:
- Bait stations: Ants are attracted by the appealing scent into a bait station. These stations may contain a sticky film or food with a slow-acting poison. The ants transport this food back to the nest, where even the queen consumes it. Within a few weeks, an entire ant nest can be eradicated.
- Professional pest control: If the infestation is too severe, such as when an entire house wall is populated from the inside, only a visit from a pest control expert will help.
Vinegar-water mixture as another home remedy
“Another home remedy besides petroleum jelly is a mixture of vinegar and water. This can be used to clean areas infested with ants of their scent trails. This way, fewer ants are attracted to follow their colony mates. A combination of cleaning with the vinegar-water mixture and petroleum jelly can be sufficient to successfully drive ants out of your home, especially in cases of light infestation.”
