BioLogic's Scanmask Beneficial Nematodes, Steinernema feltiae Sf Nematodes for Natural Insect Pest Control (100 Million with Applicator)

Last fall I sprayed the nematodes on my root knot infested garden and watered them in. The sprayer performs unevenly but after blowing a huge dose in a small area, I reduced the amount of nematode bearing contents of the package for each sprayer-full and covered my garden pretty well. Must have missed a small area because a short section of my okra row has severe root knot damage. The rest of the garden is free of root knot nematode damage. My tomatoes, peppers, beans, and squash and most of the okra row have no indication of root knot nematode damage. I will apply another dose to the nematode infected area this fall and review that about this time next year. I hope a better sprayer becomes available.

Beneficial Nematodes are highly effective to control Fleas and ticks. I use them annually!! The sprayer attachment is not effective. I use a 5 gallon backback sprayer to apply the nematodes!!

Alright here's the deal, every single time I tell people about Nematodes as our solution for gnats because we live near an aqueduct and a giant field, they think I've completely lost my mind or have been sold some ridiculous scheme.The fact is though that these actually work. The best method I've found is doing 2 applications. 1 at the start of the rainy season, and another towards the end of it about mid Spring. We live in California so that's typically mid February, and then another treatment at the beginning of April. There is a extreme difference in the gnat population when we use nematodes vs. when we do not. Last year we forgot, and it really wasn't too bad (I think because the year before had such great effects), this year they are back with a vengeance, or they were until we did another nematode treatment.1000% recommend if you're looking to reduce gnats or mosquitos.

This did not eliminate our Japanese Beetle population but we have a large acreage so we didn’t expect it to. We did, however, notice a decline in the amount of Japanese Beetles from last year so I assume that they did their job. Probably won’t invest next year because we had to spray irregardless since it didn’t eliminate them. I think it is definitely worth investing in if you have small areas you are treating. I used mine in combination with milky spore.

Not worth your time or money do not buy. They do not survive or work. They come in off temperature so they are doa and not worth wasting your money on. Save your time and money.

These little guys are wonderful. I haven't had any problems with fleas, mosquitoes or chiggers for the two years I've applied them in my new lot. It's easy are far better than buying lg expensive bags of poisonous granules. Which I need to reapply after it rains. These little guys stick around for the entire season !

Bought 50 million of these to kill crane fly larvae. Really bought them to try and eliminate the moles tearing up my lawn. I found the larvae while digging so I figured I try them as they are safe for pets. Well, it didn't deter the moles one bit, so either it didn't kill the cranefly larvae or the moles are eating something else. Since I didn't dig up the turf to see if the larvae were dead, I am giving this a 3 since I can't confirm it killed the leatherbacks. Won't buy again.

My lawn was greatly damaged by european cranefly grub. Leaving many patchy bald damaged spots. I found high number of grubs when I dug up some dead patches to place new sod. However, there were too many smaller patches of damage. I applied both Merit granules and Scanmask nematodes. In just 1 month, I was surprised all the damage area able to grow back. So far, I don't see any new damage surfacing. It appears the combination is very effective.
