Content: You can only state that they are less toxic (or in the case of some of the newer insecticides—practically non-toxic). None of the neonics or anthranilic diamides have been shown to have significant animal (meaning mammalian) toxicity. Vegetable gardens should not be an issue, as you are supposed to be applying grub control products to the lawn. Q: There is much “buzz” about Heterorhabditis nematodes. Has the technology advanced enough to make it a viable alternative to neo-nic preventative treatments? BugDoc: Insect parasitic nematodes in the genus Heterorhabditis have consistently performed better at killing soil-inhabiting insects, such as white grubs. I’m not sure this has changed, but the “buzz” has occurred because some states are prohibiting all pesticide applications to school grounds and municipal grounds. This leaves folks with the nematodes as being the only effective option.
