A few years ago my lawn became distressed when workmen took too long
in putting up our aluminum siding. Since then every August and
September, grubs invade our lawn. I re-seed in the spring only to get
the thinning and brown patches start all over again in late summer.
Chemicals are out of the question. Does anyone have advice on a way
to protect my grass, but get rid of the grubs?

Birds and moles like grubs.
