That is a perversion of what I said. Though I did say that they eat grubs, I did not say to spread poison on your yard/garden. :thumbdown:
There's lots of very beneficial insects and organisms in the ground that are good for plant growth. Kill the grubs and you kill them too. Poisons often travel through food webs like any bad thing does, you're not just killing those grubs by spreading poison, the moles will eat the dead ones and predators will eat the moles.
I'm to tired to continue explaining the obvious, why am I awake at 4 am? This is a much more interesting puzzle to ponder. :eusa_wall
Seems like if the insecticides are applied wrong is when they cause harm to unintended things. I, and most people i know around here, have used them for many years and we're still ok :crazy1:
I guess if the organic solutions were cheaper (most don't work well if at all) and were effective then insecticides would fade out but... Castor bean oil is one of the things in a lot of organic mole/gopher repellent but it doesn't always work.
You use what your budget can handle. Organics solutions aren't usually cheap and who knows what spreading millions of nematodes on your yard will do (besides kill grubs). If you can afford it, give it a try. I have no first hand experience with them but people who sell it sure are proud of it.
Then there's always traps. Humane or not, they can be a bitch to mess with but thats just another choice for ya.
