Archer Insecticide is an IGR (Insect Growth Regulator). The Archer Insecticide unique mode of action disrupts the life cycle of ants, fleas, flies, ticks, cockroaches, mosquitoes and beetles for effective population control.

  1. Low hazard, only carries a “caution” warning from the EPA.

  3. Effective when used in combination with other baits, and readily tank mixes with adulticides like Demand CS and Demon MAX, for a fast-acting, superior pest control program.

  5. Retains activity against pre-adult fleas for up to 7 months, and against pre-adult cockroaches for up to 6 months.

What is an IGR?

  1. Archer Insecticide is an IGR, or Insect Growth Regulator.
  2. An IGR is a chemical that disrupts and impede the life cycle of insects in the egg and larvae stage of development.
  3. The idea with an IGR is that if an insect cannot reach adulthood, it cannot reproduce.
  4. In short, IGR is a form of “birth control” for pests which helps keep the populations of unwanted pests under control by preventing current and future infestations.

How to Mix Archer Insecticide

Archer Insect Growth Regulator is intended to be mixed with water and applied with application equipment, such as hand-held, backpack, or power spray equipment.

  1. Fill applicator container 1/2 full with water.
  2. Add the amount of Archer Insect Growth Regulator to container as recommended in the rate table found on the product label.
  3. Shake, stir, or agitate.
  4. Fill applicator tank with water to final volume recommended in rate table.
  5. Shake, stir, or agitate again.
  6. To assure the highest quality control, prepared dilutions should be used within 24 hours and should be shaken, stirred, or agitated again if diluted material is not used for several hours.


Prior to any interior treatment, carpets, draperies and upholstered furniture should be vacuumed. The vacuum cleaner bag should be sealed and disposed of in an outdoor trash receptacle.

In Kennels and Doghouses

Treatment of kennels and doghouses will control pre-adult fleas from developing into biting and reproductive adult fleas.

  1. Prior to treatment, remove animals, pets and their food and water dishes before applying.
  2. Do not return animals and pets to treated areas until the application has completely dried.
  3. Using a tank-type applicator, apply Archer at a rate of 1 gallon diluted solution per 1,500 square feet of surface area.
  4. Apply to buildings, resting areas, walls, floors, animal bedding and run areas.
  5. Archer should not be used as an on-animal application. Pets should be treated for fleas by a veterinarian or groomer before the home is treated with Archer.

    Fleas have no chance with Archer. I mixed it with Conquer and sprayed as label told me to. Fleas and ants are no more. THANK YOU DoMyOwnPestControl, you saved me a bunch of money and kept my grand baby safe and stoped my pets from the itch.

    I used an Archer/Conquer mixture on my yard and in my house for a flea problem that was out of control. Within no time the little boogers were gone! I've tried everything and this was the ONLY product that worked. My name is Jennifer and I've been flea free for 2 weeks!

    5 of 5 stars  The BEST for Fleas....EVER
    By Kim in Bradenton, FL on 09/08/2010
    Verified Purchase

    This is one time where I feel compelled to review for the benefit of everyone who is experiencing flea infestations. My poor indoor dog was constantly scratching and biting herself raw. She suffers various symptoms when topicals are applied and I am loath to expose her to those chemicals. I live in SW Florida and the fleas were horrendous this spring. I spent a fortune and nothing worked. I found this website and discovered Archer Growth Regular and Conquer (instant knock down). Used these two in combination for everywhere inside and out. Additionally, treated the yard with Bifen (granular long term). WOW...within just a few days all fleas GONE. That was May 1st. I treated with everything again 3 months later. I have seen 2 fleas since May 1st. BRAVO, Archer, Conquer & Bifen!!!! BTW, all other bugs are dead too. I fired the pest control people and do it myself for a fraction of the cost now with ten times the results.

    By Keith in Bluftton, IN on 12/25/2010

    I am a landlord and I had a house with fleas so bad that when you entered the house fifteen minutes later my legs were covered with hundreds of fleas. I tried store bought foggers and sprays - don't waste your money. I purchased Archer IGR and Conquer and used one ounce of each in a gallon sprayer, sprayed once a week for two weeks and the problem was solved. GREAT STUFF!!

    We are using this product for the control of: DESERT COCKROACHES, SCORPIONS, CRICKETS, and EARWIGS. Very low odor that dissipates within five to ten minutes. Leaves no visible residue when mixed and applied as recommended. We are using this product with ONSLAUGHT insecticide, and since starting this regimen every three months, our results have been fantastic. Our cricket problem is actually not a problem any longer!

  • 5 of 5 stars  Best Flea Product Ever
    By Carol in Church Point, on 03/26/2016

    I have been using Archer IGR for over fifteen years. It is by far the best flea product I have ever used. I do one annual spray around my yard, kennels and barn every March and do not worry about fleas the rest of the year. I don't have to treat my dogs for fleas so that is one less chemical to either apply or give orally. I highly recommend this product.

    5 of 5 stars  Excellent product for fleas
    By Usrika in San Diego, CA on 12/11/2014

    I ordered Archer IGR along with Conquer for my house. I have two dogs and we were all getting bitten by fleas for weeks. I tried different techniques to get rid of the fleas such as baking soda, salt treatment, etc. Nothing worked. Archer and Conquer combination was awesome. Mixed them together as per the instructions and sprayed both indoors and outdoors. Not seen a flea since then. Strongly recommend these for any household with flea infestation.

    I found a flea on my indoor cat, the dogs have flea meds on them but I guess it doesn't prevent them from hitching a ride! There was a flea dirt on my cat! I freaked! I bought the archer IGR to mix in with the conquer, it worked fabulous! My cat even went to the vet three weeks later and they didn't even find any fleas or dirt on him! It worked very well, I'd buy it again in a heartbeat!

Three days later I could walk anywhere In my yard and NO FLEAS. Thank you archer andDMOPC.

    I used this product for the first time 3 years ago when I had a flea infestation in my yard. The fleas were so bad I would step outside my back door and a dozen would jump on me. After one treatment the results were immediate. I followed up with one more treatment as instructed and did not have any fleas for an entire year. I don't know how it works but it does what it says, inhibits the fleas ability to lay eggs, grow!

QOnce the product dries, is there any toxic effect to people?
I read the MSDS sheet, and I could not find any information on once the product dries or if it continues to have the same warnings as in liquid form. Also, nothing about reactivity of the product if it becomes wet. Thank you.

ANo. As with most insecticide products, the danger is when the product is liquid. People (except for the applicator) and pets should be out of the area while the product is applied, and they can safely re-enter the area after the product has dried. Archer will not re-constitute once it has dried.

QCan I use Archer IGR with a hose end sprayer? How much would I need for 1/4 acre?
I run a doggy day care with about 1/4 acre of yard. I want to apply the product quicker than with a gallon sprayer.

AYou can use Archer IGR in a hose end sprayer. You will need to apply 1 ounce of Archer IGR per 1,500 sq ft. You can mark of a 1,500 sq ft area, add the appropriate amount of ArcherIGR to the hose end sprayer and then spray until the container is empty. The exact amount of water you use isn't very important, you just need to make sure you are using the correct amount of product per 1,500 sq ft. In areas with thicker, denser vegetation you will need to use a bit more water to help the product get to the soil where these pests harbor. One bottle of Archer IGR should be enough for at least 2 treatments on a 1/4 acre property.

QHow much Archer IGR would I need to treat one acre of land?

AThe usage rate will depend on the insect you are trying to treat, but you will either need 1 or 2 ounces of product per 1,000 sq ft. Since there are 43,560 sq ft per acre, you will need 3-6 bottles of Archer IGR if you actually want to treat the entire acre. Most pests require that you only treat targeted areas, for example if you were treating for fleas you would only need to treat moist, shady areas and areas where animals spend a lot of time.

QWill my dog get sick if she chews on mulch that has been sprayed with Archer IGR and Conquer?
My concern is that one dog likes to occasionally chew on the wood mulch (and acorns that fall into that area). Is this a health concern for the dog?

AIn most circumstances the dog would have to ingest a lot of the treated mulch and acorns for there to be a health risk. Once these products are diluted and sprayed there is only a very minute amount of the active ingredients applied, only enough to have an effect on an insect.

QWould using Suspend SC and Archer work for indoor and outdoor use?
I am trying to find the best combination for my cat flea problem. I've read Suspend SC and Archer are good products. I would like to know if I can use them in a mixture together? Will they work outdoors and indoors? Are there any other products you would recommend instead of Suspend C and/or Archer?

ASuspend SC would not be a good choice for indoor flea control because it can not be used over carpeted areas, it must be kept to cracks and crevices only. A better choice would be Tengard SFR in combination with the Archer IGR. These products can be mixed together and used both indoors and outdoors for flea control.

QCan I mix Archer IGR and Talstar P to get rid of fleas indoors and outdoors? If so, what is the mixing rate?


Talstar P†is†labeled†for the treatment of fleas outdoors only. It can be mixed with Archer IGR. They can be tank mixed at one ounce for each product to one gallon of water per 1,000 sq ft.†It can only be applied to indoor cracks and crevices. Fleas will be on the open floor surfaces so it is important to apply a product to those surfaces indoors for eradication. We do carry a Outdoor/Indoor Flea Kit.

QCan Archer IGR be used on ornamental potted plants such as Orchids and Tropicals for mealybugs?


Archer IGR is not labeled for mealybugs.†When treating for mealy bugs, you could apply†TriStar 8.5 SL,†and you will use 7.5 ml (0.25oz, 1.5 tsp) per 3 gallons of water for effective control. The Tristar bottle will measure as low as 5 ml in the built-in measuring reservoir. It is suggested that you mix a surfactant with the TriStar when treating for mealybugs for better control. You can use the†Non-Ionic surfactant†we carry at the rate of 1-2 teaspoons per gallon of water.†Do not make more than 4 applications per year. Do not reapply more than once every 7 days. To determine if application is necessary, monitor pest densities.

QHow often do I have to spray Archer IGR for fleas inside my home?


Archer IGR should be used every 10-14 days when treating for fleas. We would also recommend that you use an insecticide in combination with this product for fleas, such as Temprid SC. Both of the products will be used every 10-14 days. Be sure to vacuum daily in between treatments as well. Please see our Flea Treatment Guide for more tips and information.

QWill Archer IGR harm earthworms?
I try to limit the use of chemicals in my yard to increase earthworm activity and the soil's fertility. Will this, or other IGR's, harm earthworms and beneficial nematodes? What is the least toxic outside flea treatment available?


It is possible that Archer IGR could stop the lifecycle of earthworms even though it is not labeled for them. Earthworms are considered beneficial insects and will not be found on any label.

We do carry green products, such as Essentria IC3, which is made with items that naturally occur in nature, such as rosemary and peppermint oil. This will likely last about two weeks outdoors because it will break down in the elements outdoors more quickly then a synthetic product.

Also, how often should Archer be applied? I plan on using the Bifen IT, Exciter and Archer all together but am wondering if I will have to use all three chemicals every time I spray (Bifen IT every 28 days)


Archer IGR would be mixed at .5 to 1 oz per gallon of water.  You can mix Bifen IT, Archer, and Exciter together in the same mix everytime you spray.  Both Archer and Bifen can be used every 14 days outdoors for active infestations.  Exciter is a quick contact kill only so can be used more often if needed.

QHow effective is Archer IGR in controlling the population of bed bugs?

AArcher IGR is not labeled to control bed bugs.  Many customers have had great success with the Gentrol IGR for bed bugs, as it is the only IGR that has been proven to work on bed bug reproductive cycles. While it is not guaranteed 100% of the time, many see significant differences when using the product in the speed in which they eliminate the infestation
