Crazy Ants in Phoenix, AZ
Nylanderia fulva
Crazy ants move in fast, erratic patterns and form huge colonies. Learn what draws them in and how we treat for them.
Notes: From a Phoenix, AZ Exterminator
Appearance
Crazy ants are dark brown to black with unusually long legs and antennae, and get their name from their fast, erratic, non-linear movement pattern — unlike the straight trails of most other ant species.

Harborage
They nest in a wide variety of locations — mulch, potted plants, wall voids, and electrical equipment — and are notorious for being drawn to electronics, where they can cause short circuits.
Are They Dangerous?
They don't sting and rarely bite, but large colonies can damage electrical equipment and outcompete other insect and ant populations rapidly once established.
Treatment
Their erratic movement and multiple nesting sites make crazy ants tricky to fully eliminate with a single treatment. Antidote Pest Solutions maps colony activity and treats all active nesting zones. Talk to one of Antidote Pest's Service Pro's today.
Prevention Tips
Fix leaks and standing water sources, since colonies thrive in moist areas
Seal cracks around the foundation, windows, and utility lines
Trim vegetation away from the exterior walls
Clean up sweet spills and food debris promptly
Store firewood and mulch away from the house
Behavioral Notes
Named for their fast, erratic, non-linear running pattern rather than any behavioral quirk — they dart in seemingly random directions instead of following a straight scent trail like most ants.
Crazy ants are one of the few ant species known to detoxify fire ant venom, letting them raid and outcompete fire ant colonies in areas where both are present.
