    By Gayle in Oxford, Al. on April 12, 2010

    We have 3 cats and 1 dog. Last year the fleas nearly made us all go crazy! I finally found Conquer and Archer on this web page (best prices) and finally..... FINALLY we got our lives back!!! It worked, was easy to put down, just make sure you follow instructions. About a week later.......no more fleas! It's once again time to put down in the yard. Thanks for a wonderful product that works!

    I used a Conquer and Archer mixture for my flea problem inside and in the yard and it knocked it out 1-2-3. I had used other foggers, sprays, powders and granules with no luck. Conquer and Archer did the trick.

    5 of 5 Stars  Problem Solved
    By Charles in 29 Palms ,Ca. on October 15, 2010
    Verified Purchase

    My reason for buying this product was utter desperation. We have a small dog run for an even smalller dog,Over the last 2 years we hired 3 nationally know exterminator companies for the sole purpose of erradicating an infestation of ticks from that run. All failed . One application of the Conquer Insecticide ,following the clear and simple directions, has eliminated what seemed to be an un-solvable problem.

  • 5 of 5 Stars  One Time!
    By Jennifer in Pataskala, Ohio on February 3, 2016

    I purchased a mobile home that was completely infested with fleas. The previous owners had stated they had bombed multiple times. Hmmmm. Gotta wonder it was horrible! Conquer in combination with your Nyguard IGR was my last opportunity before I turned to an actual pest control company that was going to take multiple applications and money I did not have. One application and the problem was taken care of. Once spring hits I will apply to my yard to ensure no reinfestation!

    2 of 5 Stars  Works somewhat
    By Jesse in Easton PA on October 1, 2015

    I've mixed the concentrate 1oz to a gallon like it said in the directions for fleas... Sprayed the entire house focusing on baseboards and where our dogs slept only for the fleas to return the next day... After multiple (4) sprays around the house I still have fleas... I even mixed Gentrol into the sprayer hoping to stop reproduction or maturity or the pupils. Nothing at this point is working well

    By Shane in Ooltewah on August 26, 2015

    After using a cheaper national brand of flea meds for my dogs I discovered I had made huge mistake. I went back to the old medicine but the damage was done. After doing some online research I purchased Conquer and combined it with Archer and the results were immediate.I have since began using DoMyOwnPestControl and the products they offer to treat my entire home and I have never looked back. Can't say enough about the quality of products, pricing, and service.

    After spending approximately $200, a local exterminator told me about Conquer. We have a lot of woods around our house and roaches tend to find a way in. Conquer eliminated our problem and what a relief. I was ready to sell my house and move. Thanks to the exterminator, the makers of conquer and this website domyownpestcontrol. :)

    I've been using this product since the 1980's... way before you could order it online. I used to go to a "store" in the industrial park near where I live. When they moved away, I'd drive to Collingswood, NJ to purchase it. Now, ordering online is so much easier.

    I'd tried a lot of products and spent a lot of money trying to get rid of the fleas in our carpet. An hour of my time and 2 0z. of Conquer and our flea problem is solved. I added an ounce of Precor IGR to the mix and sprayed ever inch of the carpet (about 1200 square feet). Treated the 3 cats with Advantage. They're not scratching and I haven't seen a flea in weeks. I couldn't be more pleased.

QIs Conquer safe to spray inside of a dog kennel if the dogs are present?
I would like to use this in a dog kennel with dirt floors, is it safe for the dogs to be in the area when the building is being sprayed?

ADogs must be removed from the area that is being sprayed. The dogs can return as soon as the area is dry (usually less than 1 hour).

QWhat is the mixing ratio I need to conquer these fleas with Conquer?
Got rid of dog. Back yard is now infested with fleas. 40 to 50 fleas cover my jeans when I step out back. Terrible. I will no doubt buy the IGR as well. Can I mix them together? Thanks.

AMix 1 oz of Conquer with 1 gallon of water in a hand pump sprayer and apply at a rate of one gallon per 1000 square feet. (you may also add Archer IGR to 1 gallon of the finished Conquer/water solution for more effective flea control.  Archer IGR is made for outdoors and holds up better in the sunlight. Read the product label for complete instructions and safety precautions before using the product.

December 5, 2011 Alexander from Puerto Rico asked:

QHow effective is Conquer on ticks? Would Archer IGR be a good addition?
I have a tick infestation that I've been battling for months. I have two siberian huskies that I usually bring inside during the day and to sleep at night, sometimes in the bed. I've tried another department store product, Bayer Advance Complete Insect killer, and it's proven ineffective.

AConquer is labeled for ticks and should do a great job for you. The addition of Archer IGR will be necessary to help you get control of the tick population on your property. Do not make spot applications outdoors. Treat the entire area where exposure to ticks may occur. Use more water (not more product) when treating areas with dense ground cover or heavy leaf litter. Ticks may be reintroduced from surrounding areas on host animals. Indoors, thoroughly apply as a spot treatment to infested areas such as pet beds and resting quarters; nearby cracks and crevices; along and behind baseboards, window and door frames; and localized areas of floor and floor coverings where these pests may be present. Repeat treatments will be necessary to achieve and/or maintain control during periods of high pest pressure. All of your dogs should be treated with a product that is specifically labeled for use on dogs for tick control.

You can also help by creating a "tick safe zone" in your yard. You should have an area that is at least 9 ft wide between your yard and any wooded area. Trim back trees to allow as much sunlight as possible into your yard. Keep grass as short as possible. Remove as much leaf litter as possible. A clearly defined, well manicured border between your yard and any wooded areas or weedy lots will reduce the chance of ticks infesting your yard.

January 19, 2012 Michael from Wilmington, Delaware asked:

QWhen treating for roaches, how far should bait (Max Force) be from insecticide (Conquer)?
I am particularly concerned about treating an apartment where the little kitchen is next to the larger living area. Will the bait be effective if the larger part of the apartment is repelling?

AThe Maxforce Roach Bait Gel should be applied by placing one small pea sized dot every 10-12 inches directly into cracks and crevices around counters, sinks, drawers and cabinets in kitchens and bathrooms. Conquer should be applied along baseboards, in cracks and crevices, under appliances, around door frames, window frames and in areas where utilities (cables, pipes, wires) enter into the structure. There is no set distance you need to keep the products but the general rule of thumb is to keep the baits up high around counters and inside cabinets and to keep the sprays down low near the floor area. Do not apply bait in the same exact spot where you sprayed the Conquer.

QDoes Conquer kill bed bugs?

AConquer is not labeled for bedbugs and is not intended for use on bed bugs. There are many other products on the market that have been tested and labeled for bed bugs. Phantom is one of our most popular bed bug products as it is non-repellent and there is no known resistance to this product.

October 29, 2015 Mark from Fl asked:

QDoes Conquer kill German cockroaches?

A

Conquer will kill the roaches and other insects that contact a treated surface but should not be the only product used to effectively eliminate an infestation. We would recommend one of our roach control kits. You can see the kits by clicking on the link here. We also have a great article for eliminating German Roaches here.

August 11, 2015 Matthew from Falconer, Ny asked:

QDoes Conquer act as an IGR, or does it kill adult mosquitoes?
I am specifically targeting mosquitoes in my backyard in a very wet area, with quite a bit of tall, non-mowable grass. It's their breeding ground, as it has a lot of standing water.

A

Conquer Liquid Insecticide is not an insect growth regulator; it is an adulticide. If the area you want to spray remains wet for long periods of time, you should not apply Conquer or similar insecticides in that area. Altosid Pro-G Granules is an IGR that can be used in some areas where insecticides cannot be sprayed. Be sure to follow the product label when using Altosid. Eliminating the breeding sites is ultimately the best solution. Please see our Mosquito Treatment Guide for more information about mosquito treatment.

When I enter that word in your search Conquer Liquid Insecticide comes up. One of your Q and A says do not use on Scale problems? What do I use for EHS problem?
