Advantages of ants to your garden

No matter how large a garden you own, a sufficient number of native ants present near your plants is good to keep around. In some cases, when they are not infesting the area, these diligent workers will control pests, improve pollination rates, and enrich a healthy ecosystem.

They eliminate the eggs hatch in summer and disturb the feeding process of other pests like grubs. Ants are predators and the sources of nutrients for other pest-controlling creatures such as lizards, frogs, or birds.

Instead of finding ways to kill ants, you might want to encourage them to stick around and balance the number of harmful pests in your garden.

Improve pollination rates

Like bees, groups of ants can disperse seeds and assist with pollinating since they often roam from one plant to another, seeking food sources and ant nests. Even though this pollinated action is unintentional for ants, it still helps gardeners achieve consistent fruit crops each year.

Aerate the soil

As ants start digging into the soil to build their colony, the plant roots buried deep down the surface receive sufficient oxygen, water, and nutrients. Its natural tunneling path also speeds up the decomposition of leaves and dead insects, fertilizing plants and vegetables.

Weaken root systems

While aerating the soil with the tunnels that allow water to soak into soil easier, ants might dig too many tunnels that weaken the root system. And eventually, the large population of ants may cause damage to the soil structure.

Property damage

Not only does it damage the condition of the soil, but ants can also reduce the quality of wooden trees. Carpenter ants’ habit is to hollow the wood and build their home inside.

That trees will eventually die due to the loss of nutrients and support from the trunk and branches. If your house is made of wood, you might want to double-check those wood’s condition.
