Adult Japanese beetles are susceptible to soap sprays. Soap products are most effective when they dry slowly, so spraying in the evening or at night is best.
USDA recommends
1T of soap--(the brand doesn't matter just use soap not detergent) Dr Bonner, Ivory Liquid, Dove, pure castille soap or Murphys oil soap can be used for homemade sprays.
1 c vegetable oil – canola, soybean, or neem oil.
When you're ready to spray, add one or two teaspoons of the oil-and-soap solution to a cup of water. Pour that into a sprayer and shake well before use.
Do not spray when temps are above 80 degrees Fahrenheit! Your plants may "burn" or have a reaction to what you are using in excessive heat. This is known as "phytotoxicity."

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
Some people position a bowl filled with soapy water (or oil) under the plant and tap lightly.

baking soda and warter. Mix about 3 table spoons in about a quart of water. Place in a squirt bottle and spray away. It won't usually kill them but if you spray it in areas near your door or where they hang out, the spray will deter them and keep them away.

You could try a mild detergent (dawn) in a liquid sprayer.
