Aluminum cutworm collars - any problem?

We have a problem with cutworms. I've been making collars for the plants out of aluminum flashing. I have seen some discussion of a connection between aluminum and Alzheimer's disease. I have eliminated aluminum cookware and anti-perspirants for that reason. Is there any problem with aluminum cutworm collars contaminating the soil? Maybe I should paint them, to prevent soil contact and oxidation?

    @Mark Baker What I have heard is to put a toothpick down along the stem of the plant, so that the cut worms can't cut it through.

    I put one on either side.

    This way, it would not matter about aluminum & is compostable friendly, building your soil one toothpick at a time. 😄

    I had heard of using plastic forks and placing them next to the plants to keep the cutworms off of them. Think I like the toothpick idea better. Not fond of putting a bunch of plastic in the soil.

    I should add that I leave the toothpick poking above the soil.

    Most years we just sprinkle cornmeal around our plants; it seems to deter the cutworms. We refresh it after every rain. I don't recall where we got the idea from, but we've been doing that for years.

    For different things such as worms, snails and slugs I use diatomaceous earth.

    @Annie Kate I forgot about cornmeal!
