How does one get rid of Japanese Beetles, help, they are eating my Rose of Sharon?

Question

Any and all info help is really needed, They are getting buds, on them, so will flower soon

Answer 1

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 2

you need to put some bug b gone or something similar downbefore it's time for the grubs to hatch. this will prevent them from turning in to beetles. if you already have them the flea shampoo trick might work or possibly traps. prevention is best. just buy the stuff in late winter early spring and read directions and apply. some people don't like to use the chemical method though. just makw sure you live in a place that doesn' t have a lot of runoff so this product stays out of lakes and streams,ponds,etc.

Answer 3

Go out there with a bucket of soapy water, pick them off the plant and drop them in the bucket. You might want to wear rubber gloves if you don't like touching them. If you can't reach them, knock them off with a jet of water from the hose. If it is a large rose of Sharon, I don't like the idea of spraying the whole plant because of drift, like the spray might drift back on me. I either put 'em in the bucket or just ignore them. The leaves will grow back.

Answer 4

Get a model of the USS Midway to place out in your lawn. That will definitely keep them at bay, but you may have a stray Kamikaze strike every now and then.

Answer 5

Unfortunately you can't get rid off them. Don't buy any of those traps either, they have a hormone in them that attracks them. Mix up 2 Tbsp of dish soap to a gallon of water and treat your plant

Answer 6

You can use a number of insecticides offered in garden centers, but what worked for me is this:
1:3 solution of Flea killing pet shampoo (not repellent) and water. Spray it down every day until they are gone. - It's fairly inexpensive too.
