Pests Destroyed Lawn - ID Help!

Looking for help identifying what this grub is. It appears to have destroyed most of this clients yard and i took my samples from a less damaged area just to the side of the house.

Located in Southern Ontario Canada. Thanks.

IMHO these are too small to ID from the way they are displayed. Normally we look at Hair on the Butt of the grub to ID.

From your Location I would Guess Japanese Beetle Grubs. This is a classic case of Mismanagement by a non professional. A preventative Crub Treatment should have been done back in June. I strongly suggest you get away from who ever is currently doing your Chemical application, and network with a Real Professional Company.

This is what I don't get about people, he waiting till now to call me and ask if I knew what was wrong and if I could repair it. I usually only do spring and fall clean up/aeration for this guy and I don't know why we wouldn't have called someone when his lawn started to brown out.... treatment is way cheaper then what his repair bill will be, and now really he needs both treatment and repair!!.

I told him to call someone and get it taken care of then we can schedule repair but this was more for my own knowledge.

Most common around here is white grubs but these seems to have such a dark color I thought they might be different.

If hese services are forbidden in Canada, then what is left for a person to do? Nothing!!
Watch the turfgrass slowly due and turn brown from natural processes of insects.
I wonder if milky spore is available and used in Canada!!!

Not everything is banned, just most of everything that works. You can get "organic" mixes that will help but usually only if you catch then right away before the infestation occures.

Besides them being in Canada more specifically Ontario the entire Midwest sortof had a drought this summer and I suspect there will be a lot of grub preventative failures.

I have seen a couple failures on lawns I treat or subsequently could not treat because there was no rain fore casted so it never got done on unirrigated turf.

OTOH, far fewer grubs will survive those conditions.

European chafer is the most common grub around here.

Take a look at the raster pattern under the tail for positive identification. Best time to treat is about the fourth of July, (when they are small and easily killed).
Acelypryn is the best and has very low toxicity...if you cannot even use that in Ontario, then milky spore or stienophora grub-killing nematodes are you best bet.

Also, according to MSU's Dr Dave Smitley--plenty of water allows the turf to withstand most grub attacks, up to about 5 grubs per square foot or more. Naturally, you may wish to call a pro to remove any skunks the grubs have attracted.
Naturally when you reseed, try to find better -quality more insect-resistant seed.

Oops, My Bad. I was out of my element, and I get mad when Yankees do it to warm season threads.
