Sevin Granules are pet safe when used as directed on the label. After spreading the granules across your lawn they would need to be watered in to activate the ingredients. Once they have been watered in and the water dries, pets and people are can return to the area safely. Normally a safe time frame to wait after watering is 1-2 hours.
The Sevin Insecticide Granules label calls for 3 to 7 pounds per 1000 square feet. If your spreader settings go from 1 to 10 (1 letting out the least and 10 letting out the most) you typically want to be around a 3 setting. If your spreader goes from 1 to 20, you should probably be around a 6 or 7 setting. The goal is to just run out of product when you are done walking the 1000 square feet. One person may walk faster than someone else, so they may place It on a higher setting than someone that walks slower.
Almost all fertilizers, herbicides, insecticides, etc have treatments in amounts of so much product per 1000 square feet. So if you can figure out what your walking speed is then you know anytime you apply any product that calls for so much of it per 1000 square feet, you always set your spreader on this setting. You can calibrate this by marking off a 1000 square foot (10 x 100) area and placing 4 ounces of any type of product of similar granule size, or of the extinguish in the spreader. Start with a low setting and start walking your marked off area at a normal pace. You can adjust as you go and find the basic setting for you to apply the product over a 1000 square feet.
As long as you are following the application rates on each product label you could use the Sevin Insecticide Granules and a weed and feed product at the same time.
Sevin Concentrate is labeled for chiggers. It will only kill the ones that are present during the application. In order to gain control, they must be contacted with the Sevin to have any effectiveness. We do carry Onslaught Insecticide that offers a residual after it is applied and dried for 30 days. Treatments for chiggers should begin in April/May and could need to continue through the summer as new chiggers move into the area. Treating the entire lawn is of little benefit because chiggers avoid direct sunlight and normally will not infest areas that are mowed or otherwise well maintained. Focus treatment on the unkempt areas of the lawn and lawn edge. Both Sevin and Onslaught are safe when dried. Keep the children and pets out of the area during the application until the surfaces are completely dry and then they can return.
Sevin Insecticide Granules are not labeled to killl earthworms. There are no products on the market in the USA that are labeled for earthworms as they are largely beneficial creatures. Most insecticides will not get deep enough into the soil to affect worms.
Unfortunately we are not exactly sure what setting to place the spreader on, but typically there is not a specific setting since it all depends on how fast you walk, etc…

No, Sevin Insecticide Granules have a very short half life so this should not harm your pet. Once the grubs consume the product, it is broken down very quickly within the pest so if a dog consumed them, they would not have much of the active ingredient in them still. Be sure to keep your pet out of the area until after the granules have been watered in and the area has dried.
