Kill fireants by baiting,
|Baiting for fire ants||Drench fireant mounds||Broadcast Pesticides|
This fireant article will deal with three ant elimination methods:
baiting for fireants,
drenching the fire ant mounds, and broadcasting of contact pesticides. In
many cases, these methods can be used together in a year-round program.
The best program for eliminating fireants (as well as other ants in and around structures) and controlling them throughout the year:
Drench all existing ant mounds with Cyper
TC, Cyper WP, Bifen
Talstar concentrate. At least one gallon of
finished solution is required for fire ant mounds, 1/2 gallon for smaller ones. A
good rule of thumb is to use one gallon of solution per foot of diameter of mound.
For example, a huge mound that is three feet wide (at its base) would require three
gallons of finished solution. This ensures that you kill ants deep in the colony
structure. Keep pets and children away from treated areas until dry.
Generally, it takes 1 to 2 gallons of mixed pesticide solution to drench a fire ant mound effectively. A mid-morning drench treatment is best when the sun starts warming up the colony. There are many insecticides that may be used for mound drenching, but we have the seen the best results with the following active ingredients: Bifenthrin (Talstar liquid concentrate, Talstar granules,) Cypermethrin (Cynoff EC, Cynoff WP, Demon EC, Demon WP, Cypermethrin 4 Oz.) or Permethrin (Permethrin Pro, Dragnet, Flee.) These materials are all in the synthetic pyrethrin class of chemicals. Synthetics are far more photo stable than common organophosphates (Durban, Diazinon, Malathion, Acephate) which can lose their effectiveness in as little as three hours of sunlight. Mounds properly drenched with synthetic pesticides can kill returning or foraging ants for 30 days or more! As an added benefit, synthetic pyrethroids are safer for humans and domestic animals as well as the environment, when used as directed by the label. The best example is Talstar, whose molecules actually bond to soil particles. This means that the material stays where you apply it and does not leach out into undesirable locations.

Broadcast entire area with Talstar granules. Do not spot treat. Broadcasting this professional granule ensures that all ants on the surface will contact your product. After applying your granules, apply water to the treated area. Water will help place the granules onto the surface of the soil, instead of allowing them to just rest on blades of grass. Keep pets and children off of all treated areas until dry. Talstar granules are among the safest on the market, but you must still read and follow all label instructions!
This program may be implemented 1 to 3 times per year, varying with severity of ant infestation.
When treating fire ant or other ant mounds with any contact insecticide or professional bait, do not disturb mounds before treating. If you do, the colony will immediately take the queen or queens to safety, either deep down in the mound or move them laterally to establish satellite mounds. This stressing of the colony causes more problems than anyone can imagine.
TC and Bifen
IT give the best long term
control when broadcasting large areas with a hose-end sprayer.
Baiting For Fire Ants
Top of Page
The use of professional ant baits is a very thorough method of control, slowly killing the entire colony of ants. Baits work best when used in the spring and early summer. When the weather gets hot and dry, baits are generally ineffective for fire ant control. However, fire ant baiting has two additional drawbacks: cost and length of control time. For instance, baiting an entire area will kill the existing ant colonies but rarely controls new fireant colonies and other foraging ants invading from nearby areas that were not baited properly. Also, most people with fire ant problems live on very large lots -- 2 acres or better. This involves a great deal of bait at a premium price.
The most successful baiting practice for fire ant control on turf is to use granular baits such as Advion or Maxforce Granular (or Extinguish Fire Ant Bait when baiting graze lands) in the early spring followed by soil drenches 4 to 6 weeks later if needed. Broadcast granular bait applications are most effective; however, it may take 4 to 6 weeks to give control. Early spring application is ideal because it controls recently developed queens before they leave on their nuptial flights and establish new colonies. Killing the queens is the only way to eliminate fire ant colonies. Follow-up granular bait applications usually are necessary in mid-summer and another one in the fall.
Apply baits when the ground is dry and when ground temperatures are between 70 and
90 °F with no forecast of rain. Apply baits around the base of mounds and also broadcast the entire areas where ants are seen foraging.. Baits are picked up by foraging ants looking for food. The ants take the bait back to the ant colony; it passes through the food chain and is fed to the queen ants. Granular bait recommendations are listed below.
In summer and fall, apply bait in the afternoon when temperatures are cooler because baits may rapidly degrade on hot, sunny days. By the time ants pick up the bait, the heat may have broken down the active ingredient, losing its effectiveness.
