We put on one application and will do the other one. We think it worked for our grubs. I guess we will find out in the future.

This worked great at helping control a beetle infestation (along with a beetle trap for the ones already born). I don't see any beetles after about a month and my plants are recovering.

No question, these work like a charm. Had a flea outbreak about 2 years ago, so I had to get creative. I have an IMHA dog in remission who cannot take oral flea medication or anything toxic, and the natural remedies seemed to have limited efficacy. I did a huge diatomaceous earth battle in the house (killed a vaccuum cleaner), then started a schedule of nematodes (replacing every 3 months) in the back yard. Not only does it seem to have kept fleas away, a lot of another annoying bugs avoid the yard, even ants. I used to have to go on an ant offensive every month - my neighbor behind me must have a mound the size of a small hill. They crawl through cracks in the back retaining wall and trot along the driveway cracks to my house - it was a regular battle. After two applications of nematodes I noticed they weren’t coming this way anymore. Coincidence? After 9 years I think not.

So far so good on the fleas. The Japanese beetles I fought for 3-4 weeks, killing every adult and juvenile I saw. However, since then, None. I think it took a while for the nematodes to attack the grubs in the ground, but my roses for the first time in 8 years are Japanese beetle free. Yes, I've tried killing the adults before, but they kept coming back. It took some work,but it was worth it to have my roast bush loaded with roses.

We don't know long term but after the application we have not seen anymore active termites in our beautiful red bud trees. We are really trying to save these trees because they provide one of the most beautiful buddings you have ever seen in the spring and in the very hot south they provide much needed shade for the patio and deck area. Fingers crossed and we will apply again in the spring. The nematodes also helped greatly with the Japanese beetles. Will definitely reorder. Many thanks

I've been using these beneficial nematodes for two years and they are working in my garden. I would like them to try to cut down on the packaging a bit but I understand the reason. What we need is a way to recycle the plastic.

I ordered these about a year ago including the sprayer to put them on my lawn. I have to say these worked amazingly well. Barely any mosquitoes, ants, roaches, etc. in our backyard in Texas. I have a few ants that I treat intermittently but every one in Texas knows about that. Love this product and so much safer than chemicals

This is a good product, not the easiest to mix but once that done it seems to function fine. We've had a very rainy summer in Louisiana, which means terrible fleas and armyworms...this year, for the first time in almost a decade, I do not have an infestation of either. It took about 1.5-2mo to really get things under control, but it did.I looked at it under a microscope, before and after spraying, and they were alive and strong. I kept part of my batch for 5 weeks, one week past the "use by" date, and there was still decent, but not great, vitality in the nematodes.

Them little critters sure are happy to be in my garden, and I am happy to let them do their work on my pests! Semper Fi Gunny S USMC Retired

We got a sudden smattering of fleas in an area of our yard. Whenever our dogs went to that area and came back inside we'd comb them and find one on them. Luckily we caught it early so thankfully none inside. We needed something to treat the lawn, and fast since the temps have been unusually mild, but we're in Chicago and it was October, so....winters coming. Plus, I don't like to use pesticides or harsh chemicals on either my lawn, and especially, my dogs. So I found this company after some research about beneficial nematodes. The delivery on here said a week at the fastest, but I contacted the seller, and they responded promptly that we'd have it in 2 days. They seemed fresh. I applied them easily per instructions and we seemed to have a reduction of fleas found thereafter. It's hard to judge as we went up and down to some extreme temps shortly after application (35 at night for a few days, then 60s, etc). I'm hoping we'll finally get some typical freezing temps to kill any remaining fleas this winter but you can be sure that I'm going to order a bunch more nematodes from this seller in the spring from now on.
