When the ants start dancing the tango… you know what time it is.
At the Hawaiʻi Ant Lab, we’re fighting little fire ants (LFA) with a different kind of Tango.
Tango™ contains (S)-methoprene, an insect growth regulator that stops LFA from developing and reproducing. It prevents larvae from becoming adults and reduces egg production by queens, leading to a gradual decline of the colony over time.
Tango™ is one of two products used in the Hawaiʻi Ant Lab (HAL) gel bait, which was specifically developed to control LFA.
LFA live in connected colonies with multiple queens and can nest both on the ground and in trees. Most ant baits are granular and only work on the ground—so ants in trees can survive and spread back.
The HAL gel bait solves this problem by sticking to leaves and branches, allowing treatment in vegetation as well.
The gel is made from:
• Peanut butter and vegetable oil (to attract ants)
• Water and a thickener (like xanthan gum)
• An active ingredient (Tango™ or Advion®)
