News article for October 12, 2015:
The popular topic of conversation at the fair this past week was when is it going to rain. Not sure about the when and how much but you would take advantage of the dry days of October to clean up your fire ant populations before winter. Ants are actively storing up winter food reserves right now so they are especially vulnerable to baits.
Baits can have biological controls and they can also have slow acting poisons which will allow the worker ants to take it back into the nests and share it before they meet their demise.
It should not be hard to find a 48 hour period without the forecast of rain to apply the baits. You want to apply the bait to a dry lawn and the ants will pick it all up within 48 hours.
Baits are a favorite control method because you do not have to find all of the nests. The ants will seek out the baits that you broadcast and then share.
There are several kinds of baits that can be used. The biologicals are slow to work but they are effective at destroying the nest over 6-8 weeks. Those baits would include Extinguish, Extinguish Plus, Firestrike, Distance, Logic and Award which all are broadcast at about 1.5 pounds per acre. Other baits to try would include Amdro, Seige, MaxForce FC and Spinsoid Baits such as Fertilome Come and Get It or Southern Ag Payback Fire Ant Bait.
Each bait has different application uses and rates so read the label for specific rates and application situations.
An October fire ant control application should reduce your ant populations dramatically going into winter so that colonies do not continue to grow and multiply through the winter. Late April through May would be your next treatment window which combined with this treatment should give you a good year round fire ant control program.
