In the garden, ants improve the soil, spread seeds, and control certain pests. In the house, however, they are undesirable. myHOMEBOOK reveals how a certain household remedy can help against ants.
A small, black line moving with purpose toward pantry shelves or the food bowls of dogs and cats often alerts us to the unwelcome presence of ants in our homes. Many people quickly turn to potent chemicals, which, while effective, can also be damaging to the environment. However, there are also natural home remedies that can effectively combat these tiny insects. In this article, we answer the question of how Vaseline helps against ants.
Overview
How Vaseline Helps Against Ants
Ants live in highly organized colonies. The queen ant is the leader of the colony, with all other ants serving her. They spend the whole day expanding and repairing the ant nest, taking care of the brood, and — most importantly — foraging for food. It is during this search for food that these insects may find their way into our homes.
Tiny cracks in the masonry, cable ducts, or pipes are all it takes for ants to gain entry. Individual ants usually lead the way, and when they come across a food source, they leave scent trails for the other ants in the colony. If the other ants notice the scent trails, an ant trail can quickly form to the food source and back to the ant nest to ensure that the food is transported quickly to the ant colony.
This is exactly where Vaseline can help as an effective ant repellent. Applying a thin layer of Vaseline along the ant trail achieves two things:
- The greasy layer of Vaseline obscures the scent trails left by the leading ants, causing the following ants to lose their way.
- The greasy, sticky nature of Vaseline can trap ants or force them to struggle to escape, often causing them to retreat.
Advantages of Vaseline Against Ants
- Unlike aerosol sprays or powdered ant poisons that are toxic to humans and pets, Vaseline is completely safe. Therefore, Vaseline can be a preferable solution in homes with children or pets.
- Additionally, since many people already have Vaseline at home, it allows for immediate treatment at the first sign of a minor ant infestation. Moreover, for those who don’t have Vaseline, it can be purchased inexpensively at most stores.
- Additionally, applying Vaseline is straightforward and doesn’t require any special precautions or preparations.
Using Vaseline Against Ants
To use Vaseline effectively against ants, it is important to apply it correctly:
- First, identify where the ants are entering your home. This could be, for example, leaking window frames, ventilation slots, or pipes. A thin layer of Vaseline should be applied with a cotton bud directly in front of the entry hole.
- Next, observe whether ants continue to invade living areas; if they do, another entry point may exist.
- It’s also important to reapply Vaseline regularly, as it can dry out or lose effectiveness due to dust accumulation.

When Vaseline Alone No Longer Helps
Vaseline is particularly effective against ants when the infestation is still small. If there is a large number of ants in the house, Vaseline can sometimes no longer do much. In such cases, resorting to chemical treatments is often the only effective solution. Here are some options to consider:
- Bait boxes: The ants are lured into a bait box by the appealing smell. This is either equipped with a sticky foil or contains food with a slow-acting poison. This food is transported by the ants into the nest, where the queen also eats it. Within a few weeks, this method can eradicate an entire ant colony.
- Professional pest control: If the infestation is severe and ants have infiltrated an entire wall, professional pest control services may be necessary.
