Product Overview

Criterion 0.5 G Insecticide controls and kills the eggs of soil inhabiting pests of turfgrass or ornamental plants, from cutworms and chinch bugs, to beetles and crickets. The imidacloprid in Criterion 0.5 G Insecticide sticks around, keeping your lawn safe throughout the egg laying season. Just apply the product to the soil and water the area before the insects have a chance to lay their eggs and no new pests will be born, keeping the infestation under control. Be careful not to over water, it will keep the insecticide from distributing effectively. Criterion 0.5 G Insecticide cannot be used on commercial sod farms, commercial greenhouses, nurseries, on sod farms or on grass grown for seed. Applications cannot exceed a total of 80 lb (0.4 lb of active ingredient) per acre per year.

    Dead mole crickets

    By John on 08/10/2017

    I have used criterion 0.5 before and found it to be very effective controlling the mole cricket population on my golf greens. I don't know of any product that will totally eliminate the destructive little buzzards but, with regard to price and performance, criterion 0.5 is an excellent choice.

    Agave Protection

    By Scott on 05/18/2018

    We have used Criterion 0.5 Insecticide around our agave plants in Arizona for several years. We have not had any issues with 'evil weevils' or lost an agave since the initial application. We apply two times a year and water in. A really great product!

How long is Criterion 0.5 G Insecticide effective from the time of application?

Is a 2nd application needed?


According to the product label, "The active ingredient in Criterion 0.5 G Insecticide has sufficient residual activity so that the applications can be made preceding the egg laying activity of the target pests. High levels of control can be achieved when applications are made proceeding or during the egg laying period. The need for an application can be based on historical monitoring of the site, previous records or experiences, current season adult trapping or other methods. Optimum control will be achieved when applications are made prior to egg hatch of the target pest, followed by sufficient irrigation or rainfall to move the active ingredient through the thatch." For the best timing on when to apply this product, we would recommend contacting your local cooperative extension office as they will have information on the best timing for your specific region. In most cases, adult emergence occurs in early summer, often after significant rainfall or irrigation, followed by mating and egg laying. This usually continues for four to six weeks. Under normal circumstances, Criterion 0.5 G Insecticide can provide residual white grub control for four months or longer in turf.

Is Criterion 0.5 G Insecticide formula as sticky as Merit granules?

When I use Granular Merit, it is very goopy and sticky. I'm looking for something to control Thrips in my Sun Patiens and I'm wondering if this gets gooey and sticky too. Thanks!


The Criterion 0.5 G Insectide granules may be sticky if they are not watered in thoroughly enough. This same thing could happen with any insecticide granules that may be placed on wet turf or not irrigated with enough water. It is best to use at least 0.25 inch of water to thoroughly release and distribute most insecticide granules. Be sure to store extra product in a dry area.

Is Criterion 0.5 G Insecticide the same as Merit 0.5G granules?

Yes, Criterion 0.5 G Insecticide has the same active ingredient as Merit 0.5G Granules. They are used the same way and can be applied to lawns and around ornamentals.
