50 Million Live Beneficial Nematodes Hb - Soil Pest Exterminator

For the past three years prior to 2019, my back yard was progressively dying and reached about 40% dead last Spring despite yearly applying the well known eponymous grub control product at the appropriate time and application rate . My order of 50 million HB from Bug Sales came within a few days and then were refrigerated overnight to wait for the anticipated rain which was during the second week of September 2018. Application was easily done by mixing the packet into a gallon of water, stirring well before each quart sample was poured into my hose sprayer applicator . Each quart was hosed onto about 2,500 square feet. It was applied just before sundown during a fine misty rain with a dark overcast sky. As I finished spraying, the rain came down in earnest for a couple hours and continued on/off raining for three days thereafter . Perfect conditions .For the remainder of Sept., Oct., Nov., I could not detect any improvement in grass recovery . Then at the end of Sept. for the first time I switched away from THE big brand chemical salt based fertilizer to a slow nitrogen release organic fertilizer which contained beneficial mycorrhizia and a low % of potassium ( no phosphorous ). This Spring my grasses' dormancy end was about 10 days slower than my neighbors - all of whom use chemical salt based fertilizers or a lawn service product which directly feeds the grass but does not encourage a healthy root system. Three weeks out of dormancy, and I could see those formerly dead areas pushing up grass ! Then, I applied the same organic fertilizer just before a rain and now I can report that the whole lawn is now dark green, getting thicker and some of the bare spots have new rhizomes popping up . Sure, the nitrogen in the fertilizer did green up the grass that was growing but the mycorrhyzia were re-establishing healthier roots and thus taking a little more time, but none of this would have happened without the nematodes preventing the usual grub invasion which made it possible for a healthier grass root system to be re-established . Great product !

This is the second time in a month that I have purchased this product. Right after the first purchase of nematodes was released, we had a large downpour of rain. It wasn't until after I had already used the first purchase and bought the second round of nematodes that the first ones seemed to "kick in." Our poor dogs were scratching like crazy. I didn't want to take any chances so I started to disperse the second nematode batch. I divided it into 3rds, which seemed to work better for us, since we receive a LOT of rainfall here, in this southern location. Presently, the flea problem seems to have abated, and I have one more 3rd left to distribute for next week. They last for 30 days, and I refrigerated them between uses. I purchased 50 million each time. Hope this is helpful.

I waited to give this review. We had ants, termites and fleas we needed to deal with. We got the Hb and the Sc verities. The Hb is listed as good for termite queens, ants, and adult fleas as well as many others. Hb stands for Heterorhabditis bacteriophora. I applied as soon as we received the nematodes and used them in a bit more concentrated then then was directed. The termites we had in an old tree and one wall haven't been seen since. The cat didn't have any fleas to speak of for ages despite this being a major flea area. The ants have been our major pest. Since we moved here we had been feeding them borax and sugar or Aspartame. Despite continually poisoning them they just kept coming. Found out we have Argentine Ants that have multiple queens making it next to impossible to wipe them out. Long story short the ants disappeared for months. Not a single ant for months. We couldn't believe it hardly. Talked to the neighbors who all have ants and have been poisoning and or trapping them with no end of the battle in sight. They all wanted to know about the beneficial nematodes. At least two neighbors are planning on getting some after hearing about us not having them for almost a full year. We applied it in the middle of May and only now next January are we finally seeing ants again. We will be buying more in a month or two as the weather gets a bit warmer. Worked incredibly well. UPDATE 2018: Still loving these things. I have been getting more every 1 to 1 1/2 years and have always had them arrive alive and healthy judging by how quickly the bugs disappear. I really recommend these if your having issues with the pests these are listed as attacking. UPDATE 2020: Just ordered and applied another batch. Still love them. I still feel that these are amazing and can’t recommend them enough. Buy them...seriously just get these if you have ants or termites or other pests. If you have fleas get the sc variety as those are the best for fleas. Those also have been wonderful. Did I mention that I am really impressed with these nematodes? UPDATE 2025: Just made another order of these as those little pesky ants are back. Still incredibly impressed with these nematodes. I still recommend them to everyone who mentions having issues with ants. I had last bought these in 2023 and again in the spring of 2025. I had been seeing ants in multiple rooms and the day after spraying around the outside base of our house and yard I haven't seen an ant. These are the only thing that truly works from my experience fighting ants. I also like getting the Sc-Steinernema carpocapsae beneficial nematodes for our yard. Those work great for fleas and some caterpillars.

I live on 1 acre of property so I bought 2 packages of 50 million nematodes each which was enough to do 2 acres of property . I used 1 package as per the instructions the day after I received them on about a 1/4 of of the lawn , then 2 weeks later I used the second package on the same section of lawn . I kept everything wet as per the instructions . I bought this crap for fleas and ants and have seen " ZERO " positive results . The only results I have seen are " New " ant mounds being built just a few feet away from the original ones . When I spraying this crap on the lawn , I made sure to soak the ant mounds thoroughly . Keep in mind , I used enough of this fictitious powder to do 2 acres of land on only a 1/4 of my 1 acre property . Did the nematodes I purchased die from extreme heat due to improper shipping ? Or , were there any of those things really in those 2 - $ 35 dollar packages of brown powder to begin with ? Buy at your own risk .

Good alternative for chemicals in the lawn. Easy to apply. I think they are effective, but sometimes I am not sure how to tell.
