Review: GET THIS STUFF ASAP. - Got pests? Cared for a pregnant stray cat and it never crossed your mind that it could have fleas and you got them in your house so you freaked out and had multiple panic attacks? Then this stuff is for you. I tried everything recommended to irradicate fleas and nothing worked. I was at the end of my rope and was so disgusted and exhausted from fighting them. I shelled out the money for this stuff and applied it just one time, and the fleas were gone. Legitimately gone. I did apply this stuff another time just to be safe, but it probably wasn't necessary. Let me tell you, this stuff is a complete lifesaver. I have so much left over and keep it around just to be safe. Skip everything else and buy this. You'll be glad you did.
Review: Would buy again - Works great, would buy again.

## Questions & Answers

**Q: what did you use to spray inside the house? I can't imagine using a garden pump sprayer inside...**
A: Why can't you imagine a garden pump sprayer in the house? It's what professional exterminators use. A spray bottle will give you bad hand cramps by the time you are done spraying it. I couldn't imagine not using a pump sprayer inside.

**Q: Will this product take care of drain fly larve??  i was told to clean drains, and use an insect growth regulator for preventive measures.**
A: Yes this is great. It is the best IGR for drain flies. I recommend it to all restaurants. 1- Clean the drains as good as possible, 2- use BioDrain (an enzyme/microbe cleaner) regularly to break down the food source. 3 - Use Nyguard IGR to stop existing larvae from turning to adults.

**Q: After appling MGK nugaurd to our home when can we come back.?**
A: You can remain in the home while it is being applied just stay out of the wet spray. Once dried it is perfectly safe.

**Q: What effect does this have on bees?**
A: NyGuard IGR is not labeled to control any form of bees and does not list toxicity for bees in the treated areas.

### ⭐⭐⭐⭐⭐ Would buy again

Works great, would buy again.

### ⭐⭐⭐⭐⭐ It helps a lot when dealing with acute flea problems.
*by C***S on November 10, 2025*

Some years are worse for fleas in early summer. This year was apocalyptic. I returned the favor with an apocalypse of my own. Periodic treatments with Nyguard (pyriproxifen) and Temprid (beta-cyfluthrin + imidacloprid) eventually got rid of them -- all of them. I wouldn't waste time (or spray) trying to deal with fleas without an IGR co-treatment.
