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 07/10/2012
    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 06/07/2011

    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 09/15/2011
    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.

    By John in Baxter, Tennessee on 07/31/2012

    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 in Saint Paul on 05/08/2013

    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.

    By Ralph in Evans, GA on 03/22/2016

    None of my intended targets appear to be moving around my home after application. Combined with another product, NyGuard IGR is the the long-term icing on the cake. With its ability to interrupt the pest growth cycle, it not only kills mature pests, but those that come after. I'm looking forward to putting a dent in the mosquito population as the weather improves. This will become a staple in my my home defense pesticide kit.

    5 of 5 stars  Fabulous
    By Jennifer in Pataskala, Ohio on 02/03/2016

    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! Nyguard was my last opportunity before I turned to an actual pest control company that was going to take multiple visits 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!

    5 of 5 stars  NyGuard IGR
    By Tg in CA on 11/26/2015

    Two big differences between NyGuard and other IGR's my company uses: 1. It is photostable. Most IGR's break down after a week or two in the sun, NyGuard doesn't. Means you can effectively use it indoors or out. 2. It has no odor so it can be mixed with non-repellent products. This is a big deal when dealing with social insects (roaches especially). It is the only IGR I carry in my truck, and after the current stock of Precor & Gentrol runs out it will be the only IGR my company will use from now on. Highly recommend.

    I add this to the Talstar when I spray. I have several rentals and I will spray between tenants to make certain they don't have a bug issue. I can't be certain what is working but something is. It may be a few years between tenants and the bugs do not get out of hand.

    4 of 5 stars  Outside Plan
    By Darryl in South Carolina on 10/27/2015

    We are using this outside and Ultracide inside. The plan is to stop adult fleas. It makes sense to kill adults and prevent more eggs, and the ones that are there, can not grow to the adults stage. It is the best plan that makes sense.

    By Rick in Rockwood, Tn. on 10/21/2015

    I've sprayed my indoor outdoor carpeting twice with double the recommended strength and still have fleas

    Expert Response   Expert response:
    We apologize you did not receive the expected results.Fortunately you chose a product that inhibits breeding. Nyguard does not kill fleas at all. It stops immature fleas from reaching sexual maturity which will help stop the population from growing. It is important that you use the Nyguard with an insecticide such as Onslaught or Fenvastar to kill the jumping, biting adults. You should also note that it can take 2-8 weeks to gain control. Please take a few moments to read our How to Treat for Fleas Guide to learn how implement a successful flea control program. Flea elimination will require you to use a mix of insecticide and non-chemical practices to gain control. Please let us know if we can be of further assistance. We are always happy to help! http://www.domyownpestcontrol.com/how-to-get-rid-of-fleas-a-483.html (Please be sure you follow the product label instructions and do not use more than instructed. Failure to follow these instructions can make treatments less effective and unsafe)

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.

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.

QIs Nyguard better or just more concentrated than Archer IGR? I see they have the same active ingredient.
Which, in your opinion is more a effective IGR?

AArcher Igr and Nyguard Igr are both very effective IGRs. The biggest differences between the two is the ability to hold up to sunlight outdoors. Archer is photostable for 14 days where as the NyGuard is photostable for 4-6 months. NyGuard also has a wider range of pests that are covered by its ability to sterilize and inhibit the reproductive cycles.

QIs using Onslaught and NyGuard IGR on the furniture not a good idea for treating fleas?
I read some reviews that Onslaught (even after drying) caused skin irritation.

A

Onslaught and NyGuard IGR can be mixed together and applied indoors and outdoors for treating fleas and safe if used as directed on the product labels. Onslaught is not labeled for use on furniture. We do carry products that can be applied to furniture surfaces such as Sterifab and BioDefense. We recommend that you use Ultracide for the indoor treatment as it can be used on all carpeted areas, pet bedding and upholstered furniture. Ultracide Spray contains Permethrin and Phenothrin to kill adult fleas fast. It also contains Methoprene (an insect growth regulator) to prevent reinfestation for up to seven months. Methoprene penetrates deep into the base of carpet and upholstery fibers, where pre-adult fleas live, and targets fleas in the egg and larval stages of development, preventing them from producing new infestations of breeding, biting adults. Be sure to thoroughly vacuum immediately before the treatment and every day for the next 14 days to help speed up flea elimination.

QIs NyGuard IGR stronger or more concentrated than Archer IGR?
NyGuard is 10% pyridine and Archer is 1.3% pyridine. Which one is more effective? NyGuard comes in 140 ML and Archer comes in a pint(460 ML), however NyGuard is much more expensive.

A

Nyguard is sold in a more concentrated form, but you will dilute down to the same usage rate as the Archer if you follow the product label, .01-.03%. You will get the same results when using either product.

I am currently using NyGuard IGR & Tempo SC Ultra to get rid of black and varied carpet beetles. Is this mixture effective together? Also, do I have to spray the larvae, or is the residual enough to affect the larvae if they move into a sprayed area?

A

NyGuard IGR & Tempo SC Ultra mixed together will kill and sterilize Carpet Beetles. If you can get into the cracks and crevices where the larvae or pupa are, then the products will treat for the larvae and pupa stages. There is residual left and you will need to retreat every 14 days. Also, be sure to continue to vacuum often.
