Here is a very good article from the Michigan State University Agricultural Extension Office, on the proper uses of Grub Control products to help prevent moles and all the destruction they can bring. Click on the link to see the full article and details.
How to choose and when to apply grub control products for your lawn | MSU Extension
One thing I wanted to specifically highlight here is the results of a test which found one of the most commonly sold grub control products is a complete failure at dealing with and killing / preventing grubs. This is in the article as well, but I have copied and pasted it here for quick reference to bring attention to this matter.
Please note that the ground temperature is very important in the effectiveness of applied Grub Control products. Normally, in our area, the ground temps would be where they should be by this time of the year, but this year the actual ground temps are about 12 degrees lower than they typically are this time of year, so it's important to be aware of ground temps when using these products.
""There is a widely sold trade name called Triazicide from Spectrum that lists grubs on the label and states it will control insects above or below ground and has a picture of a grub on the front of the bag. It contains only lambda-cyhalothrin or gamma-cyhalothrin. Triazicide will not control grubs. Carefully check the label for ingredients.""
3) Insecticides that DO NOT work on 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.
There are several products on the market that contain a combination of one of the preventive compounds and one of the above listed insecticides that “do not work on grubs.” The preventive ingredient will make it an effective choice for grub control.Do NOT WASTE YOUR MONEY ON THIS PRODUCT
if your goal is Grub control
I have also seen this same product in a RED Bag with Green Highlights, just the opposite coloring of this bag.........
