Best Ant Killers for Your Home and Yard

A common, effective insecticide that poisons ants when ingested. Mix it with a sweet bait like sugar or honey so ants carry it back to the colony, where it kills the queen along with the rest of the nest. Effective and inexpensive, but toxic to pets and children if ingested, so use with caution.

Products like Advion Ant Gel Bait and Raid Ant Baits combine attractants with insecticide -- ants carry the bait back and spread it through the colony. Place stations along ant trails and entry points; results take patience but offer strong long-term control.

Sprays like Ortho Home Defense kill ants on contact and can leave residual protection along trails and entry points. They provide immediate results but are less effective against the colony itself and may need frequent reapplication.

Powders like Drione Insecticide Dust work well in cracks, crevices, and other hard-to-reach nesting spots. Long-lasting, though application can be messy and may call for protective gear.

A natural powder made from fossilized algae that kills ants by dehydrating them. Sprinkle it along trails and entry points -- it's non-toxic to people and pets, but must stay dry to remain effective.

Both disrupt the scent trails ants use to navigate. Mix equal parts vinegar or lemon juice with water and spray around trails and entry points -- non-toxic, but only a temporary fix that needs frequent reapplication.

Peppermint, tea tree, and eucalyptus oils can repel ants when mixed with water and sprayed in active areas -- a natural, pleasant-smelling option, though not always strong enough for severe infestations.

Mix borax and sugar in a 1:3 ratio to attract and poison ants at once -- effective and easy to make at home, but toxic if ingested by kids or pets, so place carefully.

Products like Amdro Ant Block and Ortho Fire Ant Killer spread around the yard to target outdoor colonies. Effective for large areas and persistent infestations, but they need rainfall or watering to activate.

Targeted treatments like Hot Shot Fire Ant Killer are applied directly to a mound, often for fire ants, giving fast results -- though they only work on mounds that are directly treated.

These microscopic worms attack and kill ants and other pests when applied to the soil around mounds and nests -- a natural, environmentally friendly option that needs the right conditions to work well.

Dealing with ants effectively means combining prevention, correct identification, and the right treatment. Chemical solutions offer immediate and long-term control, natural remedies provide less toxic alternatives, and yard treatments address outdoor colonies -- regular monitoring keeps your home and yard ant-free.
