Antixx and Firefighter are both granular baits recommended by the Hawai‘i Ant Lab (HAL) to manage Little Fire Ants (LFA), Recently we discovered that some of these products have been sitting on the shelf for too long and/or have compromised seals causing them to go rancid. LFA are picky eaters, so if the bait is not fresh, the ants will not eat the bait and it will not be effective. HAL has been working with the manufacturer to resolve the freshness issue. Hawai‘i should be receiving a new fresh batch of Antixx and Firefighter by the end of March 2021.
If you have recently purchased Antixx or Firefighter, please check for freshness before use. There is a stamped date code on each package. In the example image above, it is 21 294. The first two digits represent the year it was packaged (21 = Year 2021). The next three digits represent the day of the year it was packaged (294 = Day 294 = Oct. 21). Therefore, this product was packaged on October 21, 2021. The manufacturer recommends using the bait within a year of its production. If you notice punctures in new bags or that the foil seal on a new jug of bait has failed, the bait may have spoiled, regardless of manufacturer date. Fresh bait should be fluffy corn grit and smell like fresh vegetable oil. If you notice the bait is clumpy and/or has a rancid smell when opening a new package, do not use the bait and report it directly to Neudorff at firstname.lastname@example.org to obtain a replacement.
Although we have noticed these recent issues with Antixx and Firefighter, it can happen with any granular bait product. No matter which product you use, make sure to check for freshness when opening a container or bag. If you observe similar issues with other granular baits, please let us know so we can work with manufacturers on resolving issues ASAP.
Keep up the good work everyone and happy baiting,
