Sevin insecticide granules are not labeled to kill earthworms. There are no products on the market in the United States that are labeled for earthworms, as they are largely beneficial creatures. Most insecticides do not penetrate the soil far enough to affect worms. Although earthworms are generally beneficial to lawns, sometimes their populations can get out of control.
You will then see mounds on the grass where they enter and leave the ground. Earthworms can be controlled through the use of carbamate compounds. Sevin, Turcam and Baygon are some insecticides that contain carbamate compounds. To keep the population low, you'll need to apply the insecticide two to four times a year, but no more than once every seven days.
While some pests are a nuisance, earthworms benefit most lawns and gardens by aerating the soil, improving water drainage, and introducing organic matter through decay. An organic pesticide that does not kill worms or other beneficial insects should be part of every gardener's arsenal. Following proper application procedures can ensure that the pesticide works effectively without killing worms. Have you ever wondered how to get rid of earthworms in patios or gardens? Earthworms, sometimes called night crawlers, are very beneficial for gardens and lawns.
They help break down organic matter and can enrich the soil. Anyway, they can sometimes be a nuisance to gardeners, but there are some natural ways to keep them away without the use of pesticides. If you want to get rid of insects from pills, use Spinosad, as it is one of the few things that are effective for them. Here is a link on spinosad.
Although it is not considered particularly toxic to worms, it can be toxic to other organisms in the soil. If pesticides like Sevin contain chemicals that could harm worms, they don't reach the substrate where earthworms live. In addition, you should not use these products in high concentrations. Weekly application of insecticidal soap on foliage can provide effective pest control without damaging earthworms.
A natural and non-harmful lawn treatment for worms is to simply rake castings into the lawn frequently, thus eliminating one of the least pleasant effects.
