NyGuard IGR - CASE

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.




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  I am blown away!
    By John in Baxter, Tennessee on 07/31/2012
    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 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.

    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  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.

    5 of 5 stars  Professional
    By Twig in CA on 02/18/2017

    Expensive, but works. Big difference between this and most (all?) other IGR's is it holds up to direct sunlight. Meaning you get months of residual outdoors, vs days. My company uses it. Primarily for fleas, roaches & mosquitoes. I would recommend it for the DIYer - always read & understand the label.

    5 of 5 stars  Works wonders
    By Mark in Albuquerque, NM on 09/30/2016
    Verified Purchase

    One of the reasons I like this site (domyownpestcontrol) is that for way less than the price of a pest control company's annual contract (the Big Brand Name Guys) I can get the best professional grade sprayer (B&G), and a rotation of very effective, targeted products that use different modes of action so that the pests I target don't gain resistance. Plus, unlike the pest control companies that require one year contracts with a monthly spray, I spray once every 6-12 months, sometimes even longer between treatments. The last time I had a pest control company (Big Brand Name), they were using roughly the same product (or same mode of action) every month, which is bad Integrated Pest Management, and monthly sprays build a constant or growing load of the same compound. I'd rather spray more effectively once and rotate to another mode of action if it is required. It's safer, and there is less build up of a single compound or class of compounds. Then I did a treatment spraying bifenthrin (Talstar) mixed with Nyguard, and then put down small beads of Advion bait around the inside perimeter of the garage, and under sinks where drain pipes have gaps between the pipe and sheetrock. Using the B&G sprayer, I layed down a tiny bead on my home's interior where needed, and then used the fan spray to lay down a boundary around the outside of the house, and on the of inside the garage. AWESOME INSTANTANEOUS RESULTS WITH INCREDIBLY LONG RESIDUAL CONTROL DUE TO NYGUARD!!!!! Literally, I think I went 18 months after that last treatment before I needed to spray again. Three months ago, I sprayed again but rotated to a Temprid/Nyguard mix, and a Maxforce bait. And, like the last time, the results were immediate, and thus far we have gone three months with no critters in site.

    5 of 5 stars  Nyguard and Telstar P kill Zika Virus Mosquitoes
    By Norma in St. Augustine, Florida on 09/21/2016

    I wrote before, but wanted to be sure to tell people that NyGuard with an adult insect killer has virtually done away with all fleas and mosquitoes . I said that in my last review, but so many people are worried about mosquitoes because of the Zika virus, that is in Florida, and is showing up in a few other states. Anyone pregnant or wanting to get pregnant, please protect yourself. Have someone else spray for you, and wait to go out till it is dry. Most counties do not have the funds to use these products. I have not had any mosquito bites in about 3 years, before that I got bit day and night.

    5 of 5 stars  Great product
    By Sheliaj in Webbville, KY on 08/08/2016

    We have had an extremely heavy flea infestation this year and had tried several products to control them. We are limited to what we can use because we have honey bees and do not want to spray anything that will harm them. We have used NyGuard all over our yard and have seen no adverse effects on the honey bees, but we have definitely seen a significant drop in the number of fleas. The spray is easy to mix and use, and even with a large yard, the small bottle will definitely last this year and will give us a good headstart on treating the yard next year.

    5 of 5 stars  Used for biting insects on south Florida lawn
    By Ben in BOCA RATON Fll on 06/25/2016

    I sprayed this in conjunction with Talstar and Permethin. I have used the Talstar and nyguard before but didn't get the initial knockdown, (it would take around 5 days to take affect) by adding permethrin the results where noticeable the next morning. Has been a week now and no bites on my dog or son. Using this combination usually lasts about 60 days during summer months and 90+ during "winter"

QWhat is the mixing ratio for fleas, in a 2 gal. sprayer, Talstar P and Nyguard IGR?
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.

A

If 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 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.

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.

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 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.

QIs it ok to use both NyGuard IGR and Transport GHP at the same time?
I have a roach infestation in a rental. The house has been cleaned out. I have sprayed Demand CS & Suspend Polyzone with limited success. I have recently purchased NYGuard & Transport GHP on a recommendation from a friend. Spray all 4 products? If so, what order? All all at once? Your thoughts would be appreciated.

A

You can apply an insecticide like Transport GHP and a growth regulator like NyGuard IGR at the same time.  However, you should not mix multiple insecticides as over-applying products can actually cause insects to avoid the treated areas.  You may find it helpful to take a look at our Roach Treatment Guide if you have not already done so.

QHow do I mix and apply NyGuard IGR for flea and roach treatment?
How should I mix Nyguard to treat house (indoor and covered porch area) with flea AND American Cockroach problem? Can it be applied with a regular spray bottle?

A

NyGuard IGR should be diluted with water and applied with a hand pump sprayer. For both fleas and cockroaches, it is recommend to use an adulticide (insecticide) along with the NyGuard: NyGuard will not kill existing adult insects; it will only affect immature stages. An insecticide like Onslaught Insecticide would be great to use with NyGuard for roaches and fleas. You would use 0.5 to 1.0 fl. oz. of Onslaught with 8 mL of NyGuard IGR per gallon of water and apply as a broadcast spray in areas with fleas, such as carpets. For roaches, treats cracks and crevices where these insects hide or are likely to travel. Please see our Treatment Guides for these pests for more tips and information:

QHow do you apply NyGuard IGR to rooms with hardwood floors?

A

NyGuard IGR would be applied to the cracks and crevices around the rooms with hard floor surfaces.  In most cases, the fleas will develop in upholstered furniture, pet beds, rugs and carpeted areas as hard surfaces are not very habitable for them.  Spray directly into cracks and crevices on the floor as well. Vacuuming the crevices immediately before spraying will help to remove some of the flea eggs and stimulate the developing pupa to become exposed. With heavy infestations, you may need to retreat after 14 days to get rid of the stragglers.
