13 Flowers and Plants That Attract Ants

Peonies

Peonies

Peonies buds are popular for attracting ants because they use it as a food source. Ants lick the sap juice of this plant and, in turn, encourage the flowering process, showing how a mutual relationship with each other.

Mulch

Mulches are attractive to ants because they provide water and warm surroundings for the ant colonies. It creates a humid and suitable habitat for ants and provides the best hideout to protect the ant colonies from predators. Organic mulches can also be used as a food source for ants.

Ants prefer organic mulches more than inorganic mulches. The sweet smell of organic mulches attracts the ants towards them. They do not eat wood mulches or wood chips but form tunnels. Mulches are a good attraction for carpenter ants as they love to live in decaying woods and trees.

It is essential to keep it dry and replace it regularly to prevent it from becoming a breeding ground for ants. You can also try using inorganic mulches like gravel or rocks instead of organic mulches to deter ants.
