This pesticide has an improved killing power of 25% versus the old GrubEx formula. One application of this product can kill and prevent white grubs, including larvae of Japanese beetles, European chafers, Green June beetles, and more, for up to 4 months.
A 14.35 lb. bag covers up to 5,000 square feet making it an affordable choice for Grub-prevention.
What time of the year is best to apply Scott’s GrubEx? I live in NC
According to the product label, Scotts GrubEx is best applied in spring to early summer. Application timing is very important and it varies from region to region. We recommend you contact your local cooperative extension office and speak to the master gardener on staff as he or she will be able to give you the most accurate information in regards to application timing.
Scotts GrubEx is not labeled to control earthworms, but it is not really selective. It could harm earthworms if they are in contact with a treated area long enough to be affected, although they are pretty protected by the mucus on their bodies.
