How to get rid off japanese beetles?

Question

They are coming out of the ground/lawn in clumps. Location: Western PA. We had a service which sprayed our yard and plants for the last two years. We stopped the service in April. I am open for any suggestions, whether chemical or biological. I always like homemade ideas/solutions. July 2008

Answer 1

Seven spray liquid now  that they are beetles.

Spray your plants again after a rain has washed it off.

Then before the grubs crawl out of the ground as beetles next year. Apply duraspan or diazanon granules with a spreader each spring on your lawn.

Answer 2

Here's what the Garden Web site thinks of Beetle

Traps: "Traps will attract large numbers of beetles...but the consensus is that they just bring more beetles to YOUR property, as the sexual/floral lures used in these traps travel great distances." *

They hate garlic. Someone on the gardenweb forum found a garlic-flavored olive oil spray in their cupboard and lightly sprayed their basil plants with it, & it got rid of the beetles.

Garlic spray:

Use up two cloves of garlic and a hot pepper in a pint of water. Strain, add a drop each of liquid Ivory soap and vegetable oil & spray on plants early in the morning.

You can also use a neem-based product to get rid of the beetles.

Some people position a bowl filled with soapy water (or oil) under the plant and tap lightly. They should fall out and drown in the solution. This procedure seems to be most effective in the morning or evening when the beetles are resting.

Another procedure is to spray infected plants with a mixture of 1 tablespoon isopropyl alcohol to a pint of pyrethrin mixture every 3 to 5 days.

Don't use any chemical remedy or even the "safe" organic pesticides in full sun or high temperatures because that's when they can burn or stress plants.

Landscape with plants that are known to actively repel the adults, white mums, rue, tansy, larkspur, garlic, citronella.

Long-term prevention for Japanese Beetles is biological controls such as beneficial nematodes or a product called "milky spore," which attack the grubs, and prevent recurrence for years.

Rotenone, Pyrethrum, Diazinon and Sevin sprays are also effective against adult beetles.

Answer 3

you could try mixing baby powder and water and spraying it in a broadcast spray throughout your yard. but warning  it can damage your sprayer so use a cheapo

Answer 4

White Geraniums in the flower beds, for some reason it kills them, not sure if they eat the leaf or flower.

I used them in between my roses and it works, only WHITE geraniums tho
