Last update: May 16, 2021

Ants are always seen as harmless creatures because of their small size, but they can often create havoc when raided in thousands at a single time.

They never roam alone and are always accompanied by a long stream of other ants to our disadvantage.

Farmers and gardeners always welcome ants as they work excellent to aerate the soil, but their innocuous behavior can ruin your garden once they start having more than one colony in your garden.

Apart from the usual damage, they can attract other pests and insects who then take their turn to eat, suck the plants’ nutrition out and ruin your garden.

Once their presence increases, they usually find their way into your basements and homes; their invasive behavior gets rampant during the summer season.

There are innumerable powders and sprays readily available in the market; but, they are usually crammed with harmful chemicals that have a great chance of ruining your plants, fruits, vegetables, and the soil’s nutritional properties.
