YES!! ( but, hey, it's your call.)
One of my biggest heroes is Dr.( Name Redacted ) Professor of entomology at C.U. Boulder. Nearly 20 years ago, he conducted a study using small plots of grub infested bluegrass. Measure effectiveness were, from least to greatest- 3) commercial insecticide ( I forget how many types and brands ), 2) soap ( non chlorinated powder or liquid ) and number one was a pair of nailed through plywood 'sandals' that he referred to as "spikes-o-death".
My opinion is, is that if you got the juice to kick around a manual sod cutter, great, but if you're going for an effective kill ratio, make yourself a pair of "spikes" and step away.
