Details

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.

    Sprayed for fleas got prehatched mosquito's

    By Norma 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!

    I am blown away!

    By John 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!

    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.

    This Product Works!!!!

    By Marianne 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!!!!

    Excellent product

    By Li 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.

Q
I'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.

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

Q
Best method to eradicate deer ticks

I have a deer tick problem in my yard. I'm in the process of modifying my yard to make it less tick friendly, but I want to eradicate them as well. I've been doing some research and Bifenthrin seems to be widely used for contact kill of existing ticks. I have also been reading that deer ticks are best controlled when combined with an IGR to disrupt their breeding cycle, but I'm not sure which one to choose. I am and wondering what insecticide and IGR combination you would recommend to eradicate deer ticks specifically. I have small children but no pets.

A

NyGuard IGR is a great product to use in combination with a bifenthrin product like Bifen IT.  Bifen does not kill on contact but instead will leave a residual of up to 30 days to continue to kill those ticks and other insects that contact a treated area.  Those that are sprayed directly will die faster of course but it can still take a few minutes up to a few hours or so to die after contact.  We also have great guides here that can help.

Q
Does NyGuard IGR only work on lone star ticks?

The label does not mention deer/dog ticks.

A

NyGuard IGR is only labeled for Lone Star ticks.  For deer ticks and other species, we would recommend  Archer IGR.

Q
Can Nyguard be mixed with Demand CS?

I am spraying a barn with a large infestation of spiders, ticks, flies, etc, with a one gallon B&G sprayer. Can I mix Nyguard with Demand CS for the best knockdown and control?

A

Yes, Nyguard IGR can be mixed with Demand CS. However, Nyguard IGR is an insect growth regulator. It is like a birth control for certain pests. It does not help with the knockdown of the pests. You will use 1 fl. oz. of Nyguard IGR with a gallon of water. For a severe infestation, you will use 0.8 fl. oz. of Demand CS.

If you are looking for a product to get a quicker knockdown, we would recommend ExciteR Pyrethrin Concentrate. ExciteR Insecticide with piperonyl butoxide (PBO) was designed with a pyrethroid pesticide to amplify the efficacy on pest insects.

Please let us know if you have any additional questions.

Q
Can NyGuard be mixed with Diatomaceous Earth?

Can NyGuard be mixed with Diatomaceous Earth to make a liquid nontoxic suspension to be sprayed for fleas inside a home?

A

No, it would not be recommend to mix NyGuard IGR with Diatomaceous Earth. Diatomaceous Earth is suppose to be spread & left dry not mixed with water.

Q
Can NyGuard IGR be sprayed directly on cats and dogs?

I have a really bad infestation in my home. I vacuum everyday, I have bathed all the pets. I cannot remove them all from the house to spray. I was told to get the Nyguard for lice spray and I could use that directly on the animals is that true?

A

No, neither NyGuard IGR nor NyGuard Plus is labeled to be used directly on animals. 

FLEE Plus IGR Aerosol is an insecticide spray for dogs and cats that are at least 8 weeks of age. It kills fleas and ticks to control infestations for up to 30 days and begins working within 5 minutes of application.

Q
What is best for complete flea eradication along with NyGuard IGR?

I didn't realize that NyGuard IGR only helps with reproduction. What should I mix with it…best for complete eradication? I want to kill adults too. Thank you.

A

Cyzmic CS Controlled Release Insecticide provides excellent flea control when mixed with Nyguard IGR, and provides control of dozens of insects in a powerful micro-encapsulated formulation for long-lasting control and little to no odor.  You may also need our Indoor Flea and Tick Kit if you are dealing with a flea infestation indoors.  We also recommend referring to our Flea Treatment Guide for comprehensive information on all steps needed to eradicate fleas.

Q
Pivot 10 and Bifen I/T or Nyguard IGR?

I was kinda set on a mix on pivot 10 and bifen it to help with mosquitos, various outdoor flies and gnats, and ticks. But now I'm reading about NyGuard IGR. We live next to the woods and have a pool. What do you recommend? I would like to mix a few things and get it all done together because I have a 30g towable sprayer and wand.

A

NyGuard IGR and Pivot 10 contain the same active ingredient so are comparable, either can be mixed with insecticides like Bifen IT.

Q
What is the mixing ratio for NyGuard IGR and Demand CS per gallon of water to treat the exterior perimeter foundation of the home as well as plants, trees and inside the garage for mosquitoes, ticks and other bugs?
A

NyGuard IGR is mixed at 4 to 8 mL per gallon of water for low to medium infestations and up to 12ml per gallon of water for higher level of infestations. Demand CS is mixed at 0.2 to 0.8 oz (6 to 24 ml) per gallon of water. NyGuard IGR and Demand CS can be mixed together in the sprayer for one application. One galllon per 1000 sq ft. We recommend using the higher dose on your initial application and backing down to the lower dose for maintenance.
