Above the ground they destroy the leaves on your plants!
Below the ground they destroy your Lawn!
Proper treatment is an insectorside such as Othro MAX. Improper treatment is the use of Beetle Bags. Spraying your plants with insectorside will kill the Beetles. The use of Beetle Bags will trap and kill some but will increase the total population of both Beetles and Grubs. The bait in the Beetle Bags is a sex hormone that draws the Beetles from miles around. They come, they mate and they lay their eggs in the soil. When these eggs hatch, Grubs are born. Grubs will eat your lawn and eventually grow into flying Japanese Beetle which will continue to eat the leaves on your plants. The Beetle Bags will only increase the population of the Japanese Beetle and lawn Grubs.
Please do not purchase and use Beetle Bags on your property. Any bags found within the common grounds will be removed and destroyed.
