I HAVE NOTICED SEVERAL HUNDRED JAPENESE BEETLES FLYING AROUND MY YARD WHEN IS THE BEST TIME TO KILL THE EGGS THEY HAVE LAID IN CENTRAL OKLAHOMA
For early grub control, you would apply Merit Granules 2 times a year, Spring (April-June) and Fall (Sept- Oct). Merit Granular is the longest lasting broad-spectrum grub control product on the market. You want to apply the product before egg hatch, followed by suffient rainfall or irrigation to move the active ingredient through the thatch. You will need 60lb-80lb per acre or 1.4lb - 1.8lb per 1,000sq feet.
To treat the Japanese Beetles, we recommend using Bifen IT at 1oz per 1 gallon of water. Bifen IT will give you a 30 day residual outside the home for over 75 different types of insects including Japanese Beetles as well as fleas, ticks, mosquitos, etc.
