JAPANESE BEETLES: OFF SEASON
In winter time most homeowners are not thinking about their lawn, but maybe we should. Staying on top of pest and disease will be important when our grass starts to come out of hibernation. Most lawn pest are better to be treated as preventative and not after you realize you have a huge problem, and half your lawn is gone. They are beautiful in color an dabout ⅜ to a ¼ inch wide. Usually metallic in color.
With Japanese Beetles the larva are best treated before the beetles start laying eggs in the grass. If you live in a warmer climates such as the south then this is usually middle of May and the cooler climates it would be June to July.
Products that contain Imidacloprid are really good choices for japanese beetle control. Adonis is a good generic product. How it works: Equil Adonis contains imidacloprid, the same active ingredient in Merit® Insecticide. When above or below ground chewing and sucking insects come in contact with Equil Adonis, they stop feeding and die. Imidacloprid is the most widely used insecticide in the world for turf and ornamental insect control.
Turf Protection: Equil Adonis moves laterally in the soil and provides excellent control of white grubs in turf with very low use rates.
Ornamental Tree and Shrub Protection: Equil Adonis can be applied to the soil and is taken up by the root system, then readily translocates throughout the entire tree or shrub to the areas where insects feed. Foliar applications of Equil Adonis can also be made to reduce insect populations. When the target pest insect begins to feed on a tree or shrub treated with Equil Adonis, it will stop feeding, and die.
Here is the list of Turf Pests (larvae) that it will control: Annual bluegrass weevil, Asiatic garden beetle, billbug, black turfgrass ataenius, European chafer, European crane fly, green June beetle, Japanese beetle, oriental beetle, Southern masked chafer, chinchbug (suppression), and mole crickets.
Ornamental Tree and Shrub Insects Controlled: Adelgids, aphids, armored scales (suppression), black vine weevil larvae, eucalyptus longhorned borer, flatheaded borer, Japanese beetles, lace bugs, leaf beetles, leafhoppers, leafminers, mealybugs, pecan leaf phylloxera, pecan spittlebug, pecan stem phylloxera, pine tip moth larvae, psyllids, royal palm bugs, San Jose scale, sawfy larvae, soft scales, thrips (suppression), white grub larvae and whiteflies.
Japanese beetles will lay their eggs and then turn into grubs in your lawn, but the adult can cause issues, on your trees and roses.
You may also find yourself in a bigger pickle because the grubs tend to attract other furry animals as their food source, such as skunks, armadillos and crows. Recently laid 4 pallets of sod out and had a horrible time keeping armadillo’s from tearing up the grass, because of the grubs that were transported with the soil and grass.
You can also spray your plants with a good permethrin based product to kill the adults and you can also if there are limited amounts pick them off and toss them in your neighbor’s yard (just joking), kill them.
There are Neem Oil products that work well, and can be applied during their feeding period. Neem oil does work for other pest also, such as sawflies, aphids and scale.
This is a good illustration on the stages of the Japanese Beetle.
