In May and June Japanese beetles can mean damaging grubs in your lawn later. Here are some Grub Tips. The beetles won’t damage your lawn, but the eggs they lay in your lawn hatch into grubs. White grubs can survive winter soil temperatures. When spring comes around they begin to feed again. The best time to treat grubs is when they are very young, before you are faced with severe damage. Japanese beetles often return to the same area year after year. An annual preventive program can help eliminate grubs and prevent further damage to your lawn.
Grub Tip #1: Grubs are easier to cure through preventation, so watch for warning signs like lots of flying Japanese beetles
Grub Tip #2: Grub damage may be mistaken as dry patch or drought
Grub Tip #3: If skunks and raccoons are digging in your lawn, they may be looking for dinner
Grub eat two times a year. They eat when they are emerging from the ground in May and June. They then hatch and fly around as Japanese bettles. Then the eat again in late August and September when all the Japanese beetles lay there eggs and the grubs burrow back into the gorund and overwinter waiting until the next year to start the cycle all over again.
