Scotts Grubex, Because GrubEx targets the larval stage of many insects, the best time to apply it is when the beetles burrow into lawns to lay their eggs -- in spring to early summer. When the eggs hatch, GrubEx kills the emerging larvae so they cannot develop into mature insects.,
Treating in late summer or early fall is ideal, as that is when the smaller, young grubs are most susceptible to nematodes. There is also usually a short window for application in early spring before the grubs get too big and pupate, but that is a narrower window and can be difficult to time properly.10-Aug-2017
Timing Is Everything After applying GrubEx to your lawn, you do not have to wait to apply a straight fertilizer. However, you must wait at least one week to apply a combination weed-and-feed control product after applying GrubEx, and two weeks is preferred.
To kill grubs in the spring or fall, use carbaryl or trichlorfon. Always wear rubber gloves and rubber boots when applying insecticides to turfgrass. Make sure to irrigate the lawn with at least 0.5 inches of water* and allow the grass to dry before allowing anyone or pets into the treated area.22-May-2020
The best time to apply grub control is between early spring and late summer when there's increased grub worm activity in your lawn. For grub preventers, apply between June and July just before they hatch while for grub killers, apply the treatment from spring when you see signs of grass damage.07-Sept-2020
When does GrubEx work? GrubEx begins working 60 to 90 days after being applied to the soil. Unlike Merit, which works almost immediately, it's important to distribute GrubEx from mid-April to early June. Doing so after this reduces the chance GrubEx controls grubs in your lawn.23-Feb-2022
