Do the "Beneficial" Nematodes kill our plants, trees, grass?

Nope, they kill certain insects. Or, they kill the larvae of certain insects. They have no interest in your plants and trees.

Package says harmful to fish and bees but doesn't mention earth worms. We have lots of earthworms and never noticed any difference. It could be that the dust that is sprayed on the plants is neutralized by the soil. 90% sulphur dust is used to control fleas and tics on dogs, and to control mites on poultry. You could contact your local Cooperate Extension Service.

I don't know round part plants, but I know that it kills every vegetation growing. It will not destroy any root systems, but just the above ground parts of the plants.

I don't remember it burning grass. (It's been years since we used it, and ultimately, had to resort to some evil stuff. This product killed off growth, but not the plants - they came back with a vengeance.)

If you get in on grass or your floweres it will kill them. I've used it on areas that are strictly weeds for the most part or not close to other vegetation I don't want to kill.

No what they keep away are mosquitoes but they don't kill bees or butterflies. The seeds I scattered around two years ago have produced blossoms all over the place. It makes my lawn look more natural. They are a very hardy plant.

unfortunately yes. We had to resort to something as inch worms were exfoliating most of our mature trees and creating quite a mess in the yard. We used it specifically to get rid of these worms and only used it as directed. Once the inch worms were controlled we had no need to use it anymore

Anything that dramatically increases the heat in a composter will kill your worms. This is the reason you should not put grass in a worm composter -- grass raises the temperature too high for healthy worms. Worm composting relies on a good balance of browns and greens so throwing a bunch of greens into the mix is not a good idea.

Safe enough, I'm sure, but I'm not sure they'd help. These Stienernema feltiae nematodes prey on certain insects and insect larvae. If they have no food, sooner or later they'll die. You can raise them on mealworms found at pet stores as fish / lizard food.

No it does not kill the grass. It works well and the only problem I had is that it only lasts for a short time as it kills them but doesn't last long.

I didn't see any reduction in Argentine ant activity around my yard when I used these Hb nematodes. Whether there are other nematodes that infect ants, I don't know. I kind of doubt it though, ants are great survivors.

It's been over a year since you asked this question so perhaps you've found out already. bamboo is in the grass family and Tordon is not usually effective on grasses. You're more likely to kill off your surrounding trees and shrubs.

Yes and Yes, but I have found that this is not a bad thing. Beneficial worms can come up from the soil and process your material, this is good. My compost doesn't get hot enough to make the environment bad for the worms. In case you don't know, the casings that the worms produce is very beneficial to your garden. I hope this helps answer your questions.

Should be safe. nematodes eat the larva in the ground. They shouldn't give your cat worms.

No, I doubt it was the nematodes. Follow the instructions and there should be no problems.

Yes to both nuisance plants. but it may also kill nearby plants. UR welcome.

Yes it does. I sprayed our cedar trees and it killed the bag worms. They are coming back now ,it was a year ago that I sprayed. Our trees are huge so this time we are going to let the professionals do the spraying. It kills ant too.
