Control Japanese Beetles and Take Your Garden Back!

Japanese Beetles devouring the flesh of leaves so that just the veins are left.

Do you want to get rid of Japanese beetles on your plants?

Are they eating the leaves of your favourite plants until nothing is left but the skeleton of the leaf?

Are the grubs leaving brown / dead spots in your yard?


Here are some tried and proven ways to kill Japanese beetles and their grubs.


The best and most effective way to kill them is to pick them off with your fingers or shake the branches of your plants and put the beetles in a solution of 1 tbsp dish soap and a gallon of water.

You can also vacuum them off with a vacuum cleaner and dump the bag or canister into the water solution.

This DOES work on small infestations but it is time consuming.

 

Get Rid of Japanese Beetle using Traps

Traps are another way to get rid of Japanese beetles but keep in mind that they do attract beetles from other yards as well.

You could end up with a lot of these bugs in your yard.

If you use the traps, keep them at the back of your yard, far away from your favourite plants.

You can also try using parasitic wasps and flies which are beneficial insects and will hunt them which could help control the population of the beetles.


Lawn Grub Control

If you want to get rid of Japanese Beetle Grubs spray your yard with 2 tbsp of dish soap mixed with 1 gallon of water. This will cover an area of about 1000 square feet.

When the mixture reaches the grubs, they rise out of the soil and birds will eat them.

According to the Old Farmer’s Almanac these organic sprays do work.

Nematode (available at Canadian Tire and Home Depot) will kill the grubs and any soil dwelling insects. When the grubs are still small, soak your lawn with water, apply Nematode as directed and then soak your lawn again.

Milky Spore is reported to work effectively and is a safe and organic way to control these beetle grubs or larvae.  It’s a natural occurring bacteria that is spread over your lawn and will kill the grubs before they reach adulthood.

The grubs eat the spores, which will reproduce while inside the grubs and kill them within 7-21 days but as far as I know it is only available in the United States.


Tips on Japanese Beetle Control

There are insecticides that will work to get rid of Japanese beetles but they are poisonous to honey bees and other beneficial insects so please be careful when using them.
