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.


Features:
• 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.

Directions:
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 in St. Augustine, Florida on July 10, 2012
    Verified Purchase

    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 in Roswell, GA 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  I am blown away!
    By John in Baxter, Tennessee on July 31, 2012
    Verified Purchase

    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  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  Excellent product
    By Li in Saint Paul 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.

    I can thank you for making it possible to go out in my yard now. The mosquitoes were horrible. We were actually using it for fleas, but it kept mosquitoes from hatching too. For the first time in 24 years I am not being eaten alive when I go outside.

    Nyguard did NOTHING to eliminate the pest problem we have even though I followed directions COMPLETELY! I even tried to reapply a second treatment two days after the first, our pests seemed to think it was just a nice shower for them! Very disappointed is all I can say!

    5 of 5 Stars  It worked!
    By Issa in Ohio on December 1, 2014
    Verified Purchase

    After three weeks of non-stop vacuuming, repeatedly steaming carpets (every other day), and using every spray, powder or flea bomb on available at mass retailers, I finally bought stronger pesticides. I used this in combo with D-Fense SC and we had noticeable results with the first treatment. I did have to retreat with both products a week later, but our infestation was pretty bad - we actually had one of our cats die due to the anemia caused by the blood loss from her flea bites. I wish we'd done this before my son lost his pet.

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.

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.

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.

April 28, 2015 Shawna from Pima asked:

QWhich IGR should I use?
Plan to use Tempo SC all year except the three months of monsoon season. I'll use Suspend Polyzone. Want to mix in an IGR with one or both of these (different times not all 3 products at once) and live in Arizona. I want NyGuard but it isn't labeled for that) main problem is roaches and spiders. I'd rather take a product that works overall much better than an IGR that works on scorpions but doesn't do as well all around. Separate question. Is there some way I can treat drains for cockroaches? At my work this is done periodically. I have definite issues with them coming up the drains. I'm thinking I could treat drains right before leaving for a week long vacation. Is there something or some methods you can recommend?

A

NyGuard IGR is labeled for outdoor and indoor use for various insects including roaches. It would be a great choice to mix with either Tempo SC or Suspend Polyzone. We recommend that you apply a professional roach bait gel to indoor cracks and crevices (where you are not spraying). You will want to re-apply once every two weeks (cleaning up old bait placements). You can apply a drain gel to the drains nightly for a week (when drains are not being used) and apply 2-3 squirts of Gentrol Aerosol as well. This will break up any organic matter in the drains that the roaches are attracted to and the reproductive cycle.

October 30, 2014 Michael from Jacksonville Arkansas asked:

QWhat is the shelf life if opened, but still in its original container?
Also I see it says it will last up to seven months indoors but how long will it last outside in direct sunlight and rain. I currently do not have a problem I will use it as a preventative with talstar. I was thinking 12ml per gallon ever three months. Thank you.

A Nyguard IGR has a 3-5 year shelf life as long as it is stored at room temperatures. Nyguard IGR only needs to be applied once every 5 months outdoors. It has the longest residual outdoors to sunlight and rain over all other IGR's which only hold up about 14 days.

September 13, 2014 Lori from Waterloo, Wi asked:

QIf used alone, is Nyguard safe to spray (where horses graze) in a pasture?
It has not been enough for me to treat the areas outside the pastures. Gnats, and mosquitos are bad, and in the grass, which is not terribly long but can't be cut as short as the lawn as I want to promote good grazing grass. I'd like some recommendations for natural control (IGR's and BTI if they would be safe for pasture). Essentria would be too costly long term. Thank you!

A

No, Nyguard IGR is not labeled to be used on pastures where animals graze.

For mosquitos and gnats, we would recommend focusing on the trees and/or water sources in the area. Do not spray the grazing area. Put BTI mosquito dunks in the water sources. Horses can still drink from these areas that have been treated with the mosquito dunks. For spraying, we would recommend using EcoVia. It is a natural product that can be sprayed on trees, bushes, shrubs, etc. It is not labeled to be sprayed on any type of grazing area. Please let us know if you have any additional questions.
