How to Get Rid of Japanese Beetles
One of the best methods of Japanese Beetle removal is getting rid of grubs using Imidacloprid granulars. The larval form of Japanese Beetles (grubs) cause lawn problems eating the roots of the grass.. Treating the grub forms before they emerge as an adult will help curb the population. The best time for putting the granules is to June to August catching the newly hatched grubs. The Imidaclorprid granules last for two months.
If you use a trap like the Bonide Beetle Bagger it would be recommended to use a repellent insecticide like Bifen IT or Martin's Rescue on plants. Japanese Beetles look for plant food and begin eating plants in June and July. If your plants are sprayed with such repellent insecticides, the beetles are less likely to eat the plants and are encouraged to go the Japanese Beetle Traps. Otherwise without the repellent insecticide in combination with the trap you would draw in more beetles than you trap.The traps may increase the population if used alone without the insecticide. Suggested use would be monthly with Bifen IT or Martin's Rescue. After heavy rains it would be advisable to retreat.
