NyGuard IGR

Nyguard IGR concentrate is a new Insect Growth Regulator with a broad label that delivers excellent results. This product will break even the toughest insect's reproductive cycle to stop future infestations. NyGuard IGR Concentrate is also available in convenient premeasured 1 oz bottles called NyGuard EZ1.

Active Ingredient: Pyridine 10%
Target pests: Fleas, Stored Product Pests, listed Roaches (German, Asian, and Brown-banded, Crickets, Litter Beetles, and Flying Insects
For use in: Inside and out, commercial and residential.
Pet safe: Yes, when used as directed.
Yield: 10 to 27 gallons (depending on dilution and targeted pest; see dilution tables on product label)
Manufactured By: MGK

NyGuard IGR gets to the root cause of chronic insect infestations - the eggs, larvae or nymphs - and prevents them from maturing into reproductive adults thereby controlling future infestations. NyGuard IGR will cause morphological anomalies or changes and disrupt the expected insects' state of development, leading to sterility or death. When adults are present, NyGuard is commonly used in combination with a non-IGR insecticide. This method results in rapid eradication of adults and deposits a base level of NyGuard IGR. Since this product has a long residual, it remains in place for up to seven (7) months to actively disrupt the development of any immature stages that have yet to appear, or which were not susceptible to the insecticide product used to control adult insects.

• NyGuard IGR has the broadest spectrum of insects on its label.
• NyGuard IGR is 10 times more active than Gentrol.
• NyGuard IGR is effective both indoors and outdoors.
• NyGuard IGR may be used in food and non-food areas.
• NyGuard IGR keeps working for seven months.

Apply NyGuard as a diluted spray or ULV/fogger to prevent eggs, larvae and nymphs from maturing into reproductive adults. Apply NyGuard in combination with a non-IGR adulticide to knockdown and kill existing adult populations while breaking the cycle of your toughest insect pests.

    5 of 5 Stars  Sprayed for fleas got prehatched mosquito's
    By Norma on July 10, 2012

    We used a combination of Nyguard and Talstar 1 early in June. We got an immediate kill on fleas, and other nasty bugs outside, but I wasn't expecting the destruction of the majority of the Mosquito eggs. I have lived in this house in Florida for 21 years. For 21 years I had to stay inside much of the time, at dusk especially but also all day and all night because our area had so many mosquitos. A lot didn't seem to be stopped by repellants either. We had a long dry spell and then about a week and a half after we sprayed, it begain to rain some every day, then it rained all day for several days. We needed it badly but I wasn't looking forward to being swarmed by mosquitos. I was astonished! We have had very few even at dusk, and those who managed to hatch are strange. They fly slow enough so that I can kill them before they ever land. It is like they are can't navigate normally. This is the first summer I have not gotten even one bite. I have been able to enjoy the outside again for the first time ever at this house. I reordered the same items and intend to spray one more time before the month of July is over. Just some advice to those who have houses that back up to woods, we sprayed the wooded area as well as the yard. We sprayed our neighbors yard and the small wooded area behind her house. A lot of mosquitos breed under damp leaves that pile up on the ground here in Florida. Well not anymore at may house! We even sprayed across the road in the brush. Good thing too, because they discovered the mosquitos were carrying West Nile Virus in our area. Best thing I ever did in the rhelm of insect control!

    5 of 5 Stars  This Product Works!!!!
    By Marianne on June 7, 2011

    I purchased this product as a safer product to control indoor and outdoor insects (mosquitoes, fleas, flies, roaches, ants, etc....). Nothing bothers me inside or outside after 3 months!!! It's a little slow to start, but once you get it applied around your house and inside your house, your problems are over!!! I had continual repeat flea issues from my Welsh Corgi. I treated the inside of the house and also treated the outside areas where she laid. NO MORE FLEAS!!!! And it does wonders in keeping mosquitoes under control, too!!!!

    5 of 5 Stars  A true KNOCKOUT
    By David on September 15, 2011
    Verified Purchase

    After fleas had set up house in ours we attempted to get rid of them in the usual manners (fogging and flea powder). We got desperate and were about to burn down the house (not really) and then I found this site. What a life, and house, saver. Less than 2 hours after application the fleas stopped biting and we have never had a problem since. I use it on my balcony for season long wasp and spider control and swear by it. You can't miss when you pick this product.

    5 of 5 Stars  I am blown away!
    By John on July 31, 2012

    This is the very best pest control I have ever used! I had an issue with fleas in my dog pen. I could not get them killed out for nothing until I was told about NyGuard. I used every product I could think of and spent a small fortune! A flea or two would attach itself to me when I would clean my dog pen, and next thing I knew is they were in my house too! NOT ANYMORE! This NyGuard mixed with Demize, totally killed out the fleas...inside and out in 24hrs! And they stayed gone. Now I don't even need flea collars for my dogs! Thanks for such a great product. Send me a hat or something so I can advertise for you, because your product is the best on the market...hands down! I am going to purchase more of this product so I never run out. I NEVER toot someones horn unless they deserve it...and NyGuard deserves it! So, TOOT TOOT!

    5 of 5 Stars  Excellent product
    By Li on May 8, 2013

    The person who was talking about how her cats still have fleas weeks later does not know how this product works. It stops the next generation from growing into viable adults. If you have fleas, you have to do a multi-angled approach and not just spray & pray. Seriously, if you don't know what you're doing. Don't buy the product. I've used this for years on all sorts of issues and it's as close to a magic wand as you're gonna get.

    4 of 5 Stars  I used this product in my home (severe infestation)
    By Kathleen on June 2, 2014

    I used this product in combination with professional insecticide for roaches called Demon WP and max-force roach bait I think that I saw a mager reduction in live roaches as a whole but a few but the reproduction rate was hard to see a immediate decline but after multiple applications we almost eliminated the entire roach infestation I see one every couple of days and that definitely beats seeing thousands everyday! And I still see the few stragglers reproducing so I think in-conjunction with the other products it can work some!

    Before you buy archer IGR take a look at the % active ingredient and compare with this. NyGuard costs far less and makes many more gallons. Worked great on a flea problem when combined with conquer.

November 18, 2011 Dan from Jupiter, Florida asked:

QI'm using Onslaught to control ticks. I'm thinking I should add an IGR. Is NyGuard IGR a good choice?
Onslaught's Technical Bulletin recommends NyGuard IGR for a tank mix IGR, but NyGuard's label doesn't list ticks.

ANyguard IGR does indeed list ticks on the product and Nyguard IGR would be a great choice for tick control when mixed with Onslaught.

what is the mixing ratio in a 2 gal sprayer for fleas mainly(roaches,centipedes,spiders(black widow,cane spider) problem using Talstar P and Nyguard IGR? I dont understand the mixing instructions on Nyguard IGR. Please help.

AIf you want to mix up two gallons of Talstar/Nyguard you will need to add 2 fl oz of Talstar and 6ml of Nyguard in 2 gallons of water and you will need to spray this over a 2,000 sq ft area. Please note that Talstar cannot be broadcast sprayed over carpets and furniture indoors.

QIs NyGuard IGR safe to use in a vegetable garden?
It looks like that is where the fleas have made there home. If not, what can be used to treat the soil in an edible garden?

ANyguard IGR is not labeled to be used on a edible vegetable garden.  However, we do have a product called Malathion 57% which is labeled for gardens and will treat fleas.

April 3, 2011 Kyle asked:

QHow often can I spray Onslaught and Nyguard IGR together for bird mites?
I'm thinking about ordering Onslaught to combine with NyGuard for a bird mite infestation. I realize that NyGuard isn't approved for bird mites, but I've heard success from others with this problem. I'm wondering how often this combination be used? Also, I've already used the Precor IGR, and I'm worried about using another IGR on top of it. Thanks for your response.

AWe have had several customers tell us that they have successfully used Onslaught and NyGuard together for bird mite control. Unfortunately because neither product is actually labeled for bird mites, we can not give you a definitive re-treatment time. We can say that both products do allow re-treatments after 14 days if you see renewed insect activity indoors.  There should be no problem using NyGuard IGR in a home where you have previously used Precor IGR.

QWill NyGuard work for scorpions?
I was told a local pest control company uses insect growth regulators for scorpions. Just wondering if this product will work for the control of scorpions? Thanks.

ANyguard is not labeled for scorpions. This could mean that the manufacturer has not tested this product for scorpions or that they have tested it for scorpions and felt that it was not effective for that application. We would not depend on Nyguard to be effective for scorpions.

QHow much NyGuard+Permethrin SFR per tank when using a Chaplin #6005 hose end sprayer?
Not sure how big the tank is on the sprayer. Haven't got it yet but want to use the products together in one outdoor application.

A  You should plan to use 1 2/3 oz of Permethrin SFR per gallon of water. You will need to add 3ml of NyGuard per gallon of mixture. The solution should be sprayed once every two weeks and a minmum of two treatments cycles.

QHow does watering effect NyGuard & Talstar
How soon after I apply a combination of NyGaurd and Talstar can I water the grass? What effect does it have on the chemicals?

A You generally want to wait at least 24 hours after an application of Talstar and NyGuard so that the application has time to dry and adhere to the grass and surfaces you have applied it to.  Watering too much can cause the product to lose it's effectiveness over time so you would want to apply once a month.

November 3, 2013 Matt from Arden, Nc asked:

QWill washing my walls and cleaning my carpet nullify the effects of Nylar?
I applied Nylar to my carpet and the walls in my home a few weeks ago. It's supposed to be effective against fleas for 7 months. Does that mean I shouldn't wash my walls or clean my carpets for 7 months? Will washing and cleaning nullify the effects of Nylar and other insecticides?

A Yes, steam cleaning, washing or using any type of cleaning agent on a surface you have sprayed the product on will pull the product up and break the residual down. If treating for fleas, you should be spraying once every 2 weeks with an insecticide and IGR to control the population until its gone. In between sprays you should be vacuuming daily to help pull up any dead fleas, stimulate flea eggs to hatch and suck up an debris they leave behind. Once the flea infestation is gone you can wash the carpets and walls if you need to, but it will degrade the product on the surface.

October 11, 2013 Stefanie from Vincennes, In asked:

QWhat are the names of an insecticide that stops insect reproduction?


Insecticides do not stop the reproduction cycle of the insect, they eradicate them. IGRs (insect growth regulators) halt the reproductive cycle. Some IGR's that we carry are NyGuard, Gentrol and Archer. I have included a link below to all of them that are available on our website.

QCan you use NyGuard IGR in a Hose Sprayer?
Are you able to use NyGuard IGR in a Hose Sprayer? If so, what would be the dilution rate? is it possible to use in a Sprayer with Talstar Pro?

A NyGuard IGR is typically not a product that can be used in a hose end sprayer as few sprayers will dial down to the small amount of this product that is needed per gallon. You can use it in a hand pump sprayer with Talstar at the rate of 1 ounce of Talstar and 4-8 ml of NyGuard IGR per gallon of water. Once you have treated your first time with the mixture of the two products, you can use the hose end sprayer to apply the Talstar again 30 days later while the NyGuard is continuing to work. The rate for a hose end sprayer for Talstar is the same as a pump sprayer, just put the concentrate into the reservoir, set the dial to 1 ounce and start spraying. Please let us know if you have any other questions.

August 3, 2013 Brian from Oregon asked:

QDoes Nyguard transfer to other insects through touch?
Would Nyguard make it from an ant outside the nest and transfer it inside the nest? Also, can Nyguard be tank mixed with Arilon? If so, at what rate?

A Yes the NyGuard IGR does transfer from insect to insect through touch and grooming habits so it would be carried back to the nest. NyGuard IGR, as well as all other IGRs, can be tank mixed with any insecticide to make application simpler and will not change the effects of either product. Please let us know if you have any other questions.
