When using garden fabric, protection tents or row covers aren't an option, an organic pesticide is your next step. Here is a selection of options -- primarily by Bonide.
This organic, multi-purpose pest control belongs in the tool shed of every gardener. Derived from the neem seed, it controls a wide variety of common garden insect pests and diseases. May also be used as a dormant spray to control overwintering eggs of various insect pests. Economical concentrate; mix 1 ounce per gallon of water.
It's an insecticide, a fungicide, and a miticide — and it's all-organic! Made from the oil of the neem seed, Rose Rx wards off virtually every known pest, from spider mites, whiteflies, Lily beetles and Japanese beetles to black spot and powdery mildew. It works for all flowers and ornamentals, and is safe for houseplants and food crops too.
Pleasantly scented and non-greasy. Made with a cedar oil, citronella and clove oil formula that's effective on most household insect pests. Use in kitchens, pantries, basements, garages and RVs.
These sheeps' wool pellets are an ingenious way to control destructive slugs and snails. Spread them around plants and then apply water. The moisture causes the pellets to swell, forming a dense mat of rough wool fibers that irritates the pests, encouraging them to feed elsewhere. The woolen mat also helps conserve soil moisture and acts as a weed block.
Keep extra bags on hand so your Japanese Beetle Trap is always ready to control these damaging insect pests.
This adhesive copper strip forms a protective barrier around pots or raised beds. When a slug tries to cross to feast on your plants, it's deterred by a small electric shock.
Unique blend of ingredients triggers an animal intruder's natural instinct to flee by inducing mild nasal irritation. Comes with battery-operated spray nozzle.
Spinosad is a soil-dwelling bacterium that controls dozens of insect pests: bagworms, borers, beetles, spider mites, tent caterpillars, loopers, and many, many more. Yet it has a low environmental impact because, once dry, it only kills insects that ingest it. That means you won’t harm bees or other beneficial insects (just spray in the evening when they are not active).
Control crawling insects indoors or outdoors in homes, barns, stables, vegetable, and flower gardens. Diatomaceous earth is a naturally occurring, soft, siliceous sedimentary rock that has been crumbled into a fine powder. Insects will ingest it and perish within 48 hours of contact.
Japanese beetles are voracious eaters and can cause extensive damage to many garden and landscape plants by skeletonizing leaves and ruining flowers. This pyrethrin-based insecticide is an effective way to control these pests. In addition to controlling Japanese beetles, it also controls cucumber beetles, flea beetles, cabbageworms, Colorado potato beetles, and more. Comes in a convenient, ready-to-use 32-ounce spray bottle.
Caterpillars are the eating machines of the garden. Some are able to double their weight every few days, given enough food — that is, your precious plants. Bonide Caterpillar Control eliminates cabbage loopers on broccoli, tomato hornworms — even the larvae of tent caterpillars and gypsy moths in fruit and ornamental trees. Apply at the first sign of infestation, right up to the day of harvest.
Controls destructive worms and caterpillars in and around food and flower gardens. Won't harm birds, earthworms, or beneficial insects. May be used up until day of harvest.

Use on fruit trees, shade trees, shrubs, ornamentals, roses, and vegetables. May be used up until day of harvest.
Orchard Spray protects fruit trees and bushes, nut trees, ornamentals and vegetables, naturally. It's effective against blight, blackspot, powdery mildew, aphids, mites, caterpillars, whiteflies and many, many more plant pests and diseases. Offered in a plain bottle — use for refills or with your own sprayer. Contains 32 oz. of potent concentrate.
Stop slugs from feasting on your prized hostas, strawberries and lettuces. Slug Magic pellets contain the active ingredient iron phosphate, a naturally occurring mineral. Once slugs ingest it, they stop eating and die within a few days. Sprinkle on the soil surface near affected plants — pellets remain effective for a full two weeks even if it rains.
