Japanese Beetles are especially bad this summer. In order to control them you need to use a contact killer such as Sevin (active ingredient is Carbaryl) or trap them with beetle traps and dispose of them that way. Either way is quite effective when used properly and both are available at Norway Gardens. We have Sevin in several forms -- dust, ready-to-use spray, hose-end sprayer, and concentrate. In addition, we have beetle traps which work very well when positioned to draw the beetles away from your susceptible plants. Follow package instructions and you will be pleased with the results.
At Norway Gardens we have gardening professionals available to help answer all your gardening questions.
