## Description

MGK 802958 NyGuard IGR Concentrate Insecticide, 4.73 Fl Oz, Clear

Review: GREAT PEST CONTROL - GREAT OPTION IF YOU DONT WANT TO SPEND BIG BUCKS IN A MONTHLY PEST CONTROL FEE. I USE IT AS PEST CONTROL IN MY AIRBNBS AND SO FAR, IT HAS DONE A GREAT JOB AT KEEPING PESTS OUT. I DO AN APPLICATION EVERY 8 WEEKS AND IT HAS WORKED VERY WELL, HIGHLY RECOMMEND IT.
Review: Kills Fleas (and nearly every other insect)...DEAD!! - I am not a exterminator/pest professional, only a consumer, so therefore the following recommendations should be taken as my personal and not professional advice. At first, I was disappointed at the size of the bottle I received. I did not look closely at the title or the description. However, my disappointment quickly faded, shortly after the first use. I had agreed to dog sit for my friend's Beagles. I went by his house and took my German Shepherd with me to let them play together. A few days later, my friend told me that he noticed his dogs had a pretty good amount of fleas. I held my breath and watched my dogs closely. A couple weeks past, and I began to notice my two dogs scratching. Upon closer inspection, I found my pups were crawling with fleas. My dogs were at the end of their monthly treatment flea cycle and the infestation came at the perfect/worst time. I treated my house once with Bifenthrin. (also purchased on desertcart). This did a GREAT job of killing the fleas right away, but after a couple weeks, the new ones hatched and the whole thing started over. I had originally planned to use this IGR for mosquitos next year, but decided to give it a try for the fleas. I'm very glad I did. I mixed this in with another batch of Bifenthrin and spayed the whole house and yard again. I had already retreated the dogs for their monthly flea medication, switching to Advantix II. It took about 5 days before I never saw another flea, but even after the first day of treatment with IGR and Bifenthrin there was a drastic difference. I went from picking off 20 fleas from my German Shepherd to 3. (Yeah, it was bad.) On a side note, if you want to know if your dog has fleas, but he has a thick coat/undercoat, check under his front legs/armpit region, as well as his groin around their business. The skin is soft, moist and exposed in those areas, a flea's paradise. Also, google what flea eggs look like. I had no idea. They look just like dirt! Washing linens, vacuuming, dips and monthly treatments are good mild treatments to a flea infestation, but this product brings the big guns! If you have fleas, buy this product, a jug of Bifenthrin and a 1 Gallon sprayer (I also bought a shoulder strap since the sprayer I bought did not come with one). I attached a picture of the tools you need. Mix 4mL's of this solution and 1oz of the Bifenthrin to one gallon of water for every 1,000 sqft. Wear gloves, long sleeves, mask and goggles if you are spraying upwards. Keep your animals/kids outside/inside respectively till it dries. Vacuum thoroughly. Wash all infested linens. This will end the infestation and you will get your life back! It's a little embarrassing to share all of this information, but hey, it's life and having fleas is MISERABLE, but it can happen, no matter how careful you are, so I wanted to share how I bested them. Lastly, it is important to note that since I sprayed this product & Binfenthrin 2 months ago, I have only seen 3 bugs/spiders, of any variety inside the house. 1 of which was already dead. Hope this helps! Any questions, just ask. -jP

### ⭐⭐⭐⭐⭐ It Works!
*by B***G on April 19, 2018*

I used the combination of Bifen XTS and Nyguard Insect Growth Regulator as recommended in a former review. We live in the edge of the woods and were being driven inside by mosquitos last spring. I sprayed this combo everywhere the instructions said to - bushes, trees, mulch, yard, under the deck, around windows and doors, everywhere under the porch roof and gutters, etc. I sprayed as high as I could in the trees with a backpack type sprayer with a jet nozzle. I sprayed the trees that overhang our second story deck as high and far as I could, and I sprayed the ferns in the woods. I sprayed about a 50 foot perimeter outside the house (I read that mosquitoes rarely travel more than 30 feet from where they hatch). Within 24 hours I noticed a difference. Within 48 hours, I wasn't getting swarmed to and from the car. Within a week, we could sit on the porch and drink our coffee and even spend the whole day there reading and talking and watching the hummingbirds feed. We had several evening dinner parties on the rear deck and under the front porch when it rained, and only a couple of mosquitoes were ever spotted. Anything that managed to squeeze under a door was dead or dying within a foot of the door. We love our outdoor living spaces, and the Bifen XTS / Nyguard combo gave us our outdoor spaces back. We rarely see a bug and almost never a mosquito. I got a tick on me while spraying last year, and that's the last one I ever saw. It's spring again and has been almost a year since spraying, and we are still benefiting from last year's application. We're already enjoying the porch, and there are no mosquitoes. I think the difference we're seeing this spring is due to the Nyguard keeping anything from breeding and laying eggs last year.
