    GUARDIAN - Beneficial Nematodes. Are Cranefly/Leatherjackets a problem? GUARDIAN is a Canadian Strain of beneficial Nematodes formulated to control Leatherjackets (Craneflies). The adults are slender, long legged flies that look like giant mosquitoes. They emerge in spring and autumn laying about 300 eggs. The leatherjacket larvae quickly become a serious problem for your grass and their roots. They develop a tough outer cuticle as they develop through their instars. For optimum control of this pest apply GUARDIAN nematodes in autumn while the leatherjacket grubs are still young and small and easier to control. A application can be done in the spring, it's just not as effective as in fall. AVAILABLE May thru early October. Best applied when adults are seen flying.

    Rated 1 out of 5 by from Didn't make water cloudy I've bought nematodes in the past. And one sponge will make a couple liters of water very cloudy. The sponge of nematodes I received looked relatively clean and barely changed the opacity a single liter of water. I doubt I got a good batch.

    Rated 3 out of 5 by from In response to 'not recommended to use in spring' Leatherjacket larvae in Spring have tough cuticles and are difficult for nematodes to penetrate however other body openings such as the mouth allow available penetration. Justification of spring applications are in reducing the adult population of Cranefly with a high potential of egg laying which can exceed 300 eggs per female. The coverage areas in spring (528 ft sq) is 1/2 the coverage area of autumn (1054 sq ft) to provide a higher concentration of nematodes working towards gaining results. Concerning the efficacy test, variables such as; soil depth, container size, ventilation, intervals, etc., would all have impacts on the outcome. For a better simulation, providing a food source for larvae to act naturally should be considered, otherwise larvae would starve and their bodies would shrink and be harder for the penetration process.

    Rated 2 out of 5 by from Not recommended to use in the spring After finding my garden full of Leatherjackets (cranefly larvae) in May, I was hopeful that the Beneficial Nematodes would take care of my problem. However, once I received the package by courrier (kept cold with icepacks), I read the instruction paper inside and it read that it is more effective to apply the Nematodes in October when the larvae are newly hatched and small. By now, early June, the Leatherjackets are too big and their skin too tough for the Nematodes to penetrate and kill these garden pests. I'm not saying the product is not good, but it was completely ineffective for me at this time and I will have to re-apply them again in the fall. To see if the Nematodes were effective, I actually put a few Leatherjacks in a container with some soil and watered it with the Beneficial Nematode and after 2 weeks, they are still ALIVE! So, there's the proof, it does not work in the spring. I hope to have better luck to control them in the fall when they are smaller.

    Rated 3 out of 5 by from Hoping It Works I'm not sure if this product will work or not. This is the first time I've used nemotodes to control grubs. I'll know better come spring time. It would be nice if they would have mentioned on the Home Depot website that this stuff needs to be refrigerated and that it has an expiry date. I miss the chemical days but I guess this is what we have to work with now- a-days. Hopefully it works as advertised. Simple to use but you definitely need the sprayer kit.
