Question
Lawn grubs...bad
Earthworms...good
Do products like "Grub-ex" kill earthworms as well as grubs?

Answer
Hi Bob;
Grub-ex kills EVERYTHING that moves.
If you have not put chemicals on your lawn in a couple of months or more, you could start an organic progran\m, and you could get some toads, lizards and grass snakes.
Pay the neighborhood kids a buck for every oone they bring you.
I am not sure which of these critters eat the grubs, but those are the three animals I have in my lawn livestock.
I have anole and alligator lizards, toads and grass snakes.
I have no grubs, and this, I think, is their spawning grounds.
We have every pest bug and weed i tne world, almost, n North Texas.
Cockroaches, believe it or not are beneficial.
The normally live in the soil and feed on harmful insects. We put down insecticides and kill off their food supply, so they come inside our houses to get food and hide from the poisons.
I put a 1 inch sprig of fresh rosemary on every cupboard and pantry shelf, 2 or 3 under each appliance, washyers etc, in the bathrooms, and in closet corners. Anywhere they can come in or hide, and I haven't seen a roach in my house in 10 years. Got a ton of them outside in the soil. They make bigger tunnels that earthworms, so they aerate even better.
Do you want a copy of my organic program?
