What products are not good for grubs?
Do not use products containing ONLY lambda-cyhalothrin, gamma-cyhalothrin, bifenthrin, deltamethrin, cyfluthrin or permethrin for grub control. Products containing only these ingredients will not work for grub control because the active ingredient binds with organic material and will not move down to where the grubs are feeding. These products work well for above-ground feeding insects that live on the grass leaves or soil surface, but not for insects that feed on the roots. At one garden center a clerk showed us two products, one containing only permethrin and one containing only bifenthrin, when we asked for products to control grubs. Neither of the products listed grubs on the label printed on the bag and neither of the products would have controlled grubs.

Why do you need to mow before applying insecticide?
If you are applying a product containing clothianidin, thiamethoxam or imidacloprid, the lawn should be mowed prior to the application so that no weeds are flowering in the lawn when the insecticide is applied. These active ingredients can be toxic to bees if the bees visit flowers that were recently sprayed. Mowing prior to making the application will avoid this problem by removing the flowers. Weeds that flower again after mowing are much safer than weed flowers that were sprayed directly with insecticide, but some of the insecticide is absorbed by the roots and will move into the pollen and nectar. More research is needed on this, but it could cause problems for native bees or have long-term health effects on honey bees or bumble bees. If there is nothing flowering in the lawn, there is nothing in it that would attract bees.
