Lawn Aerator Sandals: Do They Work?

Question

Do aerator sandals with 2-inch spikes actually aerate the lawn, or are they a waste of money? Brother-in-law says they don't work.

Expert Verdict

Sandals compact soil rather than aerate—hollow-tine core aerators are best. However, Colorado State University research shows sandals can kill white grubs (Japanese beetle larvae) if walked repeatedly (3-5 passes, ~2 holes per sq inch). Provides exercise and neighbor entertainment!
