Good morning just finished reading your article on beetle control. I live in fruitport MI. I have a serous beetle problem. We purchased the home last April and noticed right away beetle issues so i used sevens liquid formula over my entire yard immediately near the end of April/May. We also have another issue carpenter ants. I again used grub x in the fall to help. This spring has seen a great increase in both grubs and beetles like i have never seen before. I only own 1 acre and used 50lbs of grub control this spring. The Beatles hatched over Memorial day weekend by the thousands. I have been trying to seed my yard water my yard to thicken my grass some spots it takes some the seed doesn't. Any advise or help would be greatly appreciated. Thanks Go Spartans

The pictures were somewhat surprising. The beetle in the pictures appears to be a stag beetle, possibly Lucanus capreolus (aka Reddish-brown Stag Beetle). This beetle's larvae feed in rotting logs not on grass. The adults feed on tree sap. They do pupate in nearby soil. If your finding grubs a distance from this type of habitat you may be seeing some other turf eating grubs. The key to grub control is using the correct product at the correct time.

Note that carpenter ants indicate water damage.
Since you are having problems with over-seeding you may wish (if you haven't already) to get a soil test (http://msusoiltest.com/ ) This will help in determine what you may need to improve lawn.
