Ants are persistent creatures that can squeeze through small cracks and gaps. This is no matter how tightly you seal them. The natural remedies here will help you reduce the number of ants already inside. But keeping them out is easier said than done. Before anything else, you should seal any points of entry around windows, doors, or vents using weather stripping or silicone caulk.

Watch Out for Scout Ants

Scout ants are the ones that find food sources in your yard. They then lead worker ants back to the food source, which is usually sweet. The workers then start building a trail toward the food source. This is by laying pheromone trails on their way there. By blocking off scout ant pathways via natural means, you can at least hold back some of these worker ants before they even get to your house.

Always Clean Your Home

Ants are natural foragers. When they come across a food source, they usually take it back to the nest to feed the others. To starve ants from your home, you must clean everything meticulously and eliminate all food sources. Get rid of ants without killing them naturally. This is what you should do.

Starving them is the best natural method. Use natural cleaners that smell pleasant. But these are not too strong as they can attract other insects such as fruit flies. There are several natural ingredients that you can use as pesticides in your home. Rely on them to help prevent ant infestation in any way possible.

Sealed Stored Food

When storing natural food items like grain, nuts, or dried fruits, remember to seal the container tightly. Otherwise, ants will surely come running to your stored food!

It is natural for these foods to attract ants because they are sweet. But sealing them makes sure that all of them cannot get inside. This way of preventing ant infestation works great! Store these food items in airtight glass jars instead of plastic containers.

Repair or Seal Cracks

An ant can squeeze through a tiny crack or hole. These natural entry points offer them easy access to your house. They also come swarming in via the walls and windowsills. Make the entry points stay in good condition. This is why you must repel and seal all natural ways they use to get inside your home.

Remove Ant Trails

Ants communicate with each other by laying natural trails. Once they find the natural food sources inside your home, they leave behind pheromones as a signal to their friends. These signals stay strong for weeks. Leaving the trails attracts ants to keep coming to your house. This is no matter how tight you seal all entry points.

Deploy Ant Baits in Active Areas

The natural sweet bait for ants contains boric acid. They carry the natural toxin back to their nests and feed it to the others. Natural baits can help prevent infestation in catching them on time.
