A friend has a wild onion/garlic (I keyed it to Allium cernuum) planted
in clumps all around his property. He put it there to repel the white
grub (also from a moth) which was killing his turf and swears it works
marvelously. He gave me a start of this plant to try with the warning
that it is very invasive. I put it in the back of the jeep but almost
did not make it home. The garlic smell was so strong from that one bulb
that I was choking with the windows down. I do not have borers, but am
anxious to see if it really does help with the white grub.
Has anyone tried spreading mothballs to repel borers. Off hand, I do
not remember the chemistry of moth balls (naphthalene?) but understand
that the material will soak into the soil and help with certain pests.
Probably not very eco-friendly though. Fresh mothballs are also said to
repel deer; but that was yesterday's discussion.
