Will Sevin Kill Japanese Beetles? YES! (easy guide)

If you are someone who’s disturbed because of Japanese beetles, you are alone having these tough times. A few years ago, I also suffered because of Japanese beetles, but luckily my problem was solved by Sevin.

Japanese beetles can be troublesome when you don’t know about them. Japanese beetles are a species of beetles that are known for their massacres. The larval stages of these Japanese beetles are called grubs.

Although Japanese beetles are harmless, the same is not true for the grubs. Grubs are like maggots. Grubs are white and have dark spots around their legs. What grubs do is hide under your lawn and will feed on the roots of your dead plants. The main problem arises when there is an infestation of grubs.

In this article, I will mention everything about Sevin and why it is your best product.

What is the Chemical Composition of Sevin?

Servin used to have the chemical composition of Carbaryl (C12H11NO2), which proved to be the best chemical compound for pests.

Unfortunately, the California Department of Pesticides and Regulation(DPR) has banned the use of Carbaryl in pesticides as they believe that the use of Carbaryl has been the cause of illness in the eyes, skin and respiratory system over a long period. 

Sevin is a trade name that has been used for years now to refer to synthetic insecticides. The insecticide used to have Carbaryl as an active ingredient. You may not find Carbaryl in Sevin, but many new chemicals have been used as active ingredients, which showed great results.

Sevin’s ready-to-use spray has zeta-cypermethrin as its active ingredient. Some other Sevin products have Zeta-cypermethrin, Bifenthrin, and Cyfluthrin as their active ingredients.
