              Typically, after applying insecticide, you have to wait for a pretty long time to kill pests and insects. This means that you can’t enter the applied areas during this time.

              • Not 100% effective, but cutworms decrease significantly

              A lawn is usually pretty large. If you just have some cutworms on your lawn, I don’t highly recommend you to use insecticide. You should apply natural and efficient ways instead. If your lawn has a severe problem with cutworms, requiring you to use insecticide, a liquid treatment like Essentria Insecticide Concentrate works best.

              With granular products, it takes you more effort and time to spread granules over a large lawn. In some cases, you even have to buy a spreader to perform this task.

              This liquid insecticide allows you to apply by using a sprayer to distribute the product on a larger surface more evenly.

              How To Choose The Best Insecticide For Cutworms?

              If you choose the wrong-sized shirt, you just waste your money. However, making a wrong decision on an insecticide endangers yourself, your kids, your plants, and other beneficial insects. Before picking up any unit, make sure that your option has passed the following questions:

              Is The Insecticide Safe For Your Plants?

              As you know, cutworms love chewing seedlings and young plants that are pretty sensitive and weak. So, you shouldn’t use a too strong insecticide that has potential hazards. Some safe options include low-odor or odorless formulations or ones with low vapor pressure like bait formulations.

              You also shouldn’t choose products containing solvents like EC formulations because they are the cause of phytotoxicity. Instead, you had better consider formulations without solvents, such as CS, SC, and WP formulations.

              Which Type Of Insecticide Can Kill Cutworms?

              We can divide all insects and pests into 3 main groups: flying in the air, crawling on the ground, and hiding under the ground.

              For flying pests, the aerosol formulation is the most suitable and efficient solution.

              Cutworms belong to both 2 grounds: crawling on the ground and hiding under the ground because they live underground during the day and move on the ground to search for food at night.

              Usually, the residual spray formulation or dust can kill crawling pets. You just need to let it stay on the surface and wait for cutworms to contact it. However, this is not good for your seedlings and young plants, which cutworms want to attack. They are weak, small, and short, so it’s effortless to be affected.

              Finally, the bait formulation is the safest and most efficient way. You just need to mix this active ingredient with food or an attractive substance. The cutworms are killed by eating the bait containing the pesticide.

              Because of the selective active ingredients, make sure that cutworms are listed on the product label.

              Is The Insecticide Affected By Environmental Factors?

              Some insecticides’ effects decrease under the exposure to environmental factors.

              Here are some examples:

              The high temperature will decrease the effect of chlorinated hydrocarbon and OP insecticides. Meanwhile, the CS formulation of chlorpyrifos won’t be affected by high temperatures.

              You need to pay attention to this thing when choosing insecticide.

              Which Brands Make The Best Insecticide For Cutworms?

              If you don’t have any experience in buying insecticide for cutworms, you can believe in the product quality of the following brands. They focus on their product quality as much as possible.

              Monterey

              This brand was founded in 1963 in California, Fresno, with the old name “Monterey Ag Resources.”

              After 25 years, they became Monterey Lawn and Garden Products, which is Brandt Consolidated’s subsidiary. They sell fertilizer and plant protection products.

              Bonide

              In 1926, Bonide started producing and selling high-quality products to solve garden pests, lawn, and home problems.

              FAQs

              How do I know if I have cutworms?

              You can identify cutworms through their looks. Due to many species, it’s a little hard to identify them. They vary in colors from black, brown, green, and even pink, significantly muted stripes running along the body. They will curl up into a “C” if they are disturbed. So, you can find out the killer by running your hand over the soil and rolling over soil clumps and other potential hiding positions within one foot from where your plant is cut. You, for example, can find common black cutworms in vegetable gardens. Meanwhile, the grayish-brown greasy-looking cutworms grow up to 2 inches in length.

              If you want to look for some cutworms, you should spend time in the evening because cutworms tend to hide by day and feed by night.

              Once cutworms attack your plants, they might wilt under the heat of the sun. In severe cases, the steams are severely damaged, even cut in 2. The weaker plants (seedlings and young transplants) are, the worse conditions are.

              Cutworms usually have their burrows near the grass base to cut the blade in this area and return to their “home” quickly. When checking the lawn, remember to pay attention to the tiny tunneling holes under green excrement. If you don’t care about this thing, your lawn can be destroyed by these cutworms just after summer.

              Why do I have so many cutworms?

              Simply, it is because you grow their favorite foods - common vegetables. Some of them include tomatoes, potatoes, peppers, peas, lettuce, corn, celery, carrots, crucifers, cabbage, beans, and asparagus.

              How do you control cutworms chemically?

              The most effective way is to apply insecticides in the evening, which is the feeding time of cutworms. You just should treat the infested patches instead of the whole field to save more.

              Does hydrogen peroxide kill cutworms?

              Yes.

              How often should you apply insecticide for cutworms?

              You should apply insecticide for cutworms any time when your garden reaches the maximum severity.

              Conclusion

              What’s more, you should choose a product that can meet your needs. For example, while some work best for vegetable gardens, others are great for fruit gardens.
