Controlling Velvety Tree Ants in Oak Trees

Identifying and Managing a Persistent Ant Infestation

A Fresno foothills homeowner battles black-and-red biting ants (likely velvety tree ants, *Liometopum occidentale*) trailing between oak trees. Standard insecticides fail because they only kill foraging workers, not the colony.

Effective Bait Strategy

Velvety tree ants are attracted to sweet baits. Use a liquid borate bait like Drax Liquidator. Foragers carry it back to the nest, eventually killing the queen and colony. Contact sprays provide only temporary relief.

When to Call Professionals

Given the difficulty of reaching canopy nests and the ants' resilience, hiring a licensed pest control company experienced with velvety tree ants is the most reliable long-term solution.
