What insecticides kill grubs?
There are two chemicals, carbaryl and trichlorfon, that are considered curative treatments. They are short-lived compounds that kill all life stages of grubs. These two insecticides are the only options if high numbers of grubs are found in the fall and in spring before early May. Our research indicates they will kill 20-80% of grubs when applied in September or 20-55% when applied in late October. They are not as effective as the preventive compounds in reducing grub numbers.
Where are the active ingredients on a grub control?
The active ingredients are usually shown on the bottom right or left of the front of the bag and listed as a percent of composition.
How long does it take for carbaryl to kill grubs?
Both compounds work equally well on Japanese beetle grubs. It will take 10-14 days for the grubs to begin dying after the insecticide is applied. One trichlorfon product has “24 Hour Grub Control” in its name and would seem to indicate that it will kill grubs in 24 hours. However, even trichlorfon should not be evaluated for at least five days after application (assuming it rains or irrigation was applied), and carbaryl may need three to four weeks to be effective. Do not apply any curative compounds in the spring after May 15 as grubs stop feeding in late May as they prepare to pupate. As with the preventive products, lawns should be mowed immediately before applying carbaryl or trichlorfon to protect bees.
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.
When to apply grub control?
They will not work on grubs found in the lawn from the middle of October through the middle of May. However, when applied in June or July they provide excellent protection against the next generation of grubs. So, if you need to apply the preventive insecticide BEFORE the grubs are there, how do you know if you need to use an insecticide or not? If you confirmed grub damage the previous fall or spring, meaning you found lots of grubs, then you may want to use a preventive insecticide for one or two years to build a more dense turf that will be tolerant of grubs. If you have treated for several years and you do not see evidence of grubs in your lawn or in the neighbor’s lawn, it may be time to stop treating. There is an erroneous philosophy being perpetuated that because we have European chafers and Japanese beetles in the area, it is necessary to treat every year or your lawn will be damaged by grubs. This is not true.
When do grubs appear in lawns?
Grub damage may appear in home lawns from mid-September to November or from March to early May.

How to prevent grubs from laying eggs?
Lawn Cutting: Preventing grubs isn’t just about handling the grubs under the surface, it’s about preventing beetles from laying eggs in the first place. No eggs = no grubs. One way to do so is to keep your grass a little bit longer (3-4 inches). This is because beetles prefer sun exposure to lay their eggs. If your lawn is a bit longer, it will not offer the sun exposure that these beetles prefer, and they will find a more attractive location for egg-laying.

The Turf Type Tall Fescue, as found in our Tuff Turf Grass Seed, is also less likely to show signs of Grub Damage, because its roots are so extensive that a little feeding by Grubs doesn't usually cause many problems. Shallow rooted grasses, like Creeping Bentgrass, show a lot of damage from Grubs because there are far less roots to help it survive.
