Conquer Insecticide and Leaf Cutter Ants

It is recommended that you drench the mounds with a weakened diluted residual insecticide;such as Conquer Insecticide at 1 oz per 5 gallons of water.
If spraying the leaf cutter trails as a residual insecticide, use 2 oz per gallon. The trails are very visible looking like a worn path (bare ground).

Conquer Insecticide For Inside Flea Control

Mix 2 oz of Conquer with 1 gallon of water in a pump sprayer. It is advisable at this point to add 1 oz of an insect growth regulator (IGR) with methoprene such as Precor, Meteor or Equil in order to cut the flea cycle. All of these IGR's have the same percentage of methoprene (1.2%) and are used the same way.

Recommended IGR's : Meteor IGR, Precor IGR , or Equil S-Methoprene 1.2% IGR.

Spray on carpets, rugs and upholstery. If your pet gets under the furniture, spray underneath as well. As with all insecticides, read the label.

Excellent Insecticide for killing fleas
I had a small yard with indoor/outdoor dogs and about once a year every few years we would get hit with fleas inside and outside. Archer IGR mixed with Conquer Liquid Insecticide, sprayed throughout the yard and house worked great. We also used Ultracide indoors to kill adult fleas. One application was all it took to kill every flea. There was never a need for a second application to get the job done. These three products used together will fix any flea infestation you have.

Review by Bugman / (Posted on 5/6/2020)
I've had exterminators here for leaf cutter ants and they all tell me there is nothing to treat them with.
CONQUER is the best! I've chased them out of my yard completely! If only my neighbors would do the same, because their colonies raid my yard..... but they sure don't nest at my place anymore!
Review by JW / (Posted on 2/12/2019)
Very effective product for its intended use.
I have been battling cut ants for several years with very little success. I had been using wasp spray to spray the trails and mounds only to have them return within a night out two. Some of these trails would extend for 150 or more feet above ground and more than 300 or more feet away grom the main mound. I have spent thousands of dollars battling these pests to no avail.

They have destroyed several ornamental trees, Crepe Myrtle trees, a beautiful 40 foot tall Ligustrum tree, and several Live Oak trees with repeated over night stripping of the leaves. Just as the trees would begin to recover the ants would swarm them again taking all of the new growth until the tree was unable to recover from the repeated assaults.

I have been researching ways to kill them and recently ran across an article recommending this product. I purchased a bottle albeit with little hope for success. To my amazement this stuff has been very effective. Just this summer alone I have been able to significantly reduce the amount of activity to almost nothing. I sprayed the main 60 x 100 ft mound with one ounce per gallon of this product in combination with 50 pounds of DE and in two weeks no more mound. This thing was a hive of activity even after several treatments of DE over the years with little effect. The DE reduce the amount of activity for awhile until a good rain but then return when the DE was washed away. I am convinced that the addition of the Conquer finally killed the mound. It will be nice to not have to worry about them next year. Thanks for a great product.

Very satisfied customer

Conquer Works
I've had problems with Leaf Cutter Ants for several years and have tried several different methods to eradicate them. Some worked, sort of, and some didn't work at all. After using Conquer, one application per instructions, and one colony has been eradicated. after 2 weeks, still no sign of any workers. Now on to the other four colonies. I applied to each entry point and each trail leading to/from the entrance making sure to wet the awaiting leaf portions to be carried down to their "kitchen". I'm very pleased with the performance of Conquer and to this web site.

seems to be working
I think it's working, to get rid of leaf cutter ants. It doesn't work the first time but takes several applications, 2 or 3. But I'm encouraged so far.

Cutter Ants
I have been around South Texas Cutter Ants for a long time. So far, it's too early to tell. Treating their holes is like playing "Wac-a-Mole". You treat one mound and the next day, they pop up in new hole, but so for, none have returned to a previous location. I irrigate their nest and exit hole thoroughly. I'll let you know in about 30-days,

Review by Dale / (Posted on 4/9/2016)
Works better than everything else we tried
Did not completely eradicate our out of control cutter ant problem, but certainly helped us get it to a more manageable level. This product really does work.
Review by Pete / (Posted on 12/8/2015)
It works
This product has earned a positive report. The way we used your product, Conquer Liquid Insecticide, has given us very positive results. We mixed your product according to your instructions and then placed the nozzle of our sprayer at the entrance of the cutter ants hole. We sprayed your liquid into the hole and counted to 25. Then we sprayed around the entrance until the sand was damp. This killed the Queen and kept the area from being re-infected. It works.
We have since reordered more of your product which has proven it is very successful.. Thanks.

Great experience!
Absolutely the best flea treatment! Yes it has an odor. It's no secret because... Yes it is a pesticide. I've never had an issue with harm to any of our animals in any way! Yes it kills the critters it claims. Very well I might add. If you want something strong and powerful for a great price... This is your product. Nothing compared to the store bought products.

Did what it said. Killed the colony of fire ants. Easy to mix.
Review by Rad / (Posted on 6/8/2015)
very satisfied
I have tried for years to get rid of leaf cutter ants. This product worked with one application. Just used it today on fire ants. Again it worked with one application. Going to spray for spiders next week after I power wash my house. I'll be happy to give another review. I live at the lake with provides many types of unwanted insects. .
Review by gg / (Posted on 4/9/2015)
Wow! Just read the Conquer Product Label in PDF at the bottom of the page (previous to reviews). This stuff is lethal! Highly toxic to all life forms, including breathing and absorbing through skin. Not even remotely safe to use if you have kids or pets. Why would anyone consider using something so toxic in their home? There are safer ways to deal with bugs! This is not one of them!

DIY RESPONSE: Thanks for your feedback. One thing to consider is that label warnings typically referring to the undiluted concentrate. Dried residues that have been diluted by water and sprayed are typically far less toxic. Conquer falls into the "Low Toxicity" range based on its toxicity numbers. The EPA requires insecticides to carry one of three signal words: Caution (Lowest Toxicity), Warning, or Danger (Highest Toxicity). Conquer carries the word "Caution".

Great product
I use it to kill spiders, it did the job.
Review by SB / (Posted on 7/23/2014)
excellent product for flea control
I live in SC, where the fleas are horrible and used this outside, (with Nylar), when I had a horrible flea problem on my dogs . I sprayed twice over the last 3-4 years, and have not seen a flea since. I do treat my dogs with Revolution, just in case, but no longer even see a flea when Revolution is wearing off.
