Extinguish Plus for Myrmica Rubra
By Jeremy on 07/08/2010
I have been studying the effectiveness of various toxins in controlling a serious northern fire ant infestation on a small island off the coast of Maine. So far, the most practical combination seems to be an Insect Growth Regulator (IGR) followed by Hydramethylnon. Initially, I used Methoprene (Extinguish) and hydramethylnon (Amdro) sequentially, separated by about a week, then, a few weeks later, followed up with the two together (Extinguish-Plus). This seems to have virtually eliminated the fire ants from the treated area, at least for the present season. In another area, I used the Extinguish-Plus alone about a week ago. So far I have seen many piles of dead ant carcasses, indicating that the bait is working, but there are still plenty of worker ants busily carrying away more carcasses, so only more time will tell whether the substances used together is as good as the two used separately. I welcome the experience of others using these and other toxins.

Best product I have tried
By Steve on 05/14/2014
I have been using Extinguish Plus for the past 3 years. I have found it to be effective in controlling the population of fire ants. I use a Herd Kasco GT-77-ATV Broadcast Seeder/Spreader for ATV's to distribute Extinguish Plus. I follow the instructions provided by Auburn University based on the Moundville Study. The study reveals that it is better to eliminate most of the mounds, not all and let the remaining ones kill off new invaders. I apply in May and late August and only when the ants are active. Late in the day, after sundown. Drop a few potato chips around and if ants are present in 15 to 39 minutes, it is the time to apply. There seems to be a residual effect as I find fewer new mounds before treatment. Precision application is the key and the spreader provides exact distribution.

Dead ants that don't come back, but use it quickly

Kills fire ants quickly, and they don't come back. The only down side is it goes bad in just a few months, even faster if exposed to moisture (like the heat and humidity here in Austin), so keep in inside not in the garage or shed.

Too early to tell
By Dave on 12/31/2010
I moved into a new property where the prior owners weren't so good about treating for fire ants and there were hills everywhere. With 3 dogs I wanted to make sure that the yard was safe for them so I spread this over 3 acres in November and within about a week all the active ant hills died. Within the next week, however, I noticed new ant hills sprouting up and have been spot treating them. Come springtime I plan to do another broadcast spreading and am hopeful that will get things under control.

Kills, but.....
By Nick on 04/24/2016
Our new property in Florida was neglected, except for ants. Tons of species, sizes, mounds and areas covered with the lil bastards. Following directions, waiting for them to forage, dry, cool mornings and sparse spreading didn't solve issue. I needed to repeat several times, week after week, and then still have to treat mounds as they continue to survive. Problem has improved over time, but not a quick fix for sure. Good Luck.

Fire Ants

Great stuff
By Steven on 04/14/2023
The product works very well, and it did not take the 8 weeks they said, No fire ant beds in my yard after a couple of days. The reason for a 4 star, it was hard to distribute 1lb per acre. How ever I weighted out a pound and then I had to get a little more because I spread too much but it was very effective, I will use this again.

Extinguish Plus works well.
By Kent on 10/19/2024
I walked a pass every 40 feet across my 5.25 acres to be treated and used my battery powered spinner spreader to apply 12’ width bands. Fire ants will range to 100’ from their hill, so they all received bait exposure. A week later, I backtracked and took the top off of raised (due to heavy rains) fire ant dirt mounds and normally, they come boiling out for defense. Not a single ant! But, what I did find was several “grains” of Extinguish Plus inside their hills. Very effective! I will switch it up with a different active ingredient the next application so they can’t build resistance. Extinguish Plus is a nice product. One has to constantly tap the sides of the spreader hopper, or the product will bridge and not keep dispensing onto the spinner. Very doable, though! No dust. I wear personal protective clothing/rubber gloves/goggles. I worry about people that pay no attention to label information and go out in shorts to apply an insecticide! But, I have had a commercial pesticide license in my career and understand the dangers of NOT following labels!
