Sprays have the benefit of being ready to use and require no extra mixing. Insecticides are sold in typically four different formats: sprays, concentrates, powders, and granules.

| Concentrate or Ready to Use? Ready to use It is best to apply on days where rain is not in the forecast.Īpplication Type: Powder | Location: Indoors or outdoors | Target Pest: Ground-dwelling insects, arachnids, and snails | Coverage Area: 10 lbs, about 5,000 ft. We note that if you reside in one of the wetter states, diatomaceous earth turns to sludge when moistened. Since snails are mollusks, insecticides are not designed for their control, and there are few safe options on the market. When applied around the perimeter of a home or the garden, it offers control from ground dwelling insects like beetles and roaches.ĭiatomaceous earth is one of the few products out there that may be effective against snails. While hard for the eye to detect, the diatoms have sharp edges that prevent insects from being able to walk over them, stopping them in their tracks. It also happens to make a great multi-pest control. The granules last up to eight weeks (about two months), and we recommend that you apply them multiple times throughout the growing season.Īpplication Type: Granular | Location: Lawn, flower beds, around trees | Target Pest: Lawn, flower beds, Around trees | Coverage Area: 20,000 square feet | Concentrate or Ready to Use? Ready to useĭiatomaceous earth is composed of diatoms (plankton) fossils and has myriad uses, including paints, toothpastes, and water filters. These granules are not meant to be used on edibles and cannot be applied in vegetable gardens or around fruit trees. The formula can be used in flower beds, around trees, and on the lawn, if they are in areas children and pets are unlikely to discover them. These systemic granules contain imidacloprid, which can kill many varieties of insects. Once applied, the granules are watered into the soil, where they are slowly absorbed by plants, offering protection against any insect wanting a snack. If spraying chemicals is something you are hoping to avoid, granular formulas offer equal control and are simple to use. If you want to preserve pollinators and beneficial bad bug predators, be sure to spray targeted plants with care.Īpplication Type: Spray | Location: Yard | Target Pest: Broad-spectrum, over 30 pests | Coverage Area: 5,000 square feet (about the area of a basketball court).

Also, since this is a broad-spectrum insecticide, it can harm all insects, including butterflies and bees. Imidacloprid is not to be used where pets frequent your yard. Rainproof in minutes, you need fewer applications.

The three-in-one product name refers to a few extra chemicals that fight fungi and even arachnids such as mites, which traditional insecticides do not cover, and common pathogens such as rose black spot, anthracnose, and powdery mildew. Coming in a spray or a concentrate form, both are easy to use and offered at an affordable price point, frequently under $10. Imidacloprid is broad-spectrum, meaning it combats a wide variety of insects. This garden spray features imidacloprid, an insecticide that has been available in products in the United States since 1994. The Spruce Home Improvement Review Board.
