Bacillus thuringiensis subspecies kurstaki (Btk) is a microbial insecticide that kills only caterpillars. It's safe to use near bees,
Mix 2 tablespoons of neem oil with 1 gallon of water and a few drops of dish soap. Spray directly on affected areas. DIY Insecticidal Soap: Mix 1-2 tablespoons of mild liquid soap (not detergent) in a quart of water. Spray on the worms and affected plants to suffocate them.
Spray Azadirachtin 1.0 % EC (10000 ppm) 2.0 ml/ lit. or apply Bacillus thuringiensis 2g/lit. during evening hours. Plough the soil to expose and kill the pupae. Grow castor along border and irrigation channel as trap crop.
The solution is to spray any newly planted annual that is being eaten with Captain Jack's. For added protection, dust these with diatomaceous earth after the Captain Jack's dries. For gardens where the slug or earwig population is high, Sluggo Plus can also be scattered around vulnerable plants.
Hot pepper spray for plants acts as a safer, more sustainable and natural alternative to traditional pesticides—and it doesn't hurt that it's cheap to make. It only requires pantry ingredients, is safe for the environment and will make sure your garden flourishes.
We know that sometimes we will end up with only vines left because the leaves have all been eaten, but given enough time, the leaves will grow back, and the flowers will bloom. Soon the butterflies will be laying eggs again, and the caterpillars will be munching on them again.
For a potent homemade caterpillar deterrent, combine crushed chili, garlic cloves, dishwashing liquid, vegetable oil, and turmeric with water. Let the mixture sit for a while before spraying it generously on both sides of the leaves.
Vinegar spray: A vinegar and water solution will kill and repel most garden pests, including caterpillars. Mix two tablespoons of vinegar with 1 gallon of water, and spray wherever you've seen caterpillars.
One way that people have tried to kill harmful worms is to create a 1:10 or 1:20 vinegar to water solution in a spray bottle and spray it on the garden. This vinegar hack works but it will also kill your beneficial worms and kill or damage your plants.
Making Fungicide with Baking Soda
In addition, this mix protects against aphids, whiteflies, thrips, caterpillars, spider mites, roaches and ants. When the mix is consumed by insects it releases carbon dioxide into their system which kills them.
Non-chemical remedies like using natural mixtures with peppermint, garlic, or rosemary and water, or a gentle dish soap dilution can also be effective. Remember to keep your plant environment clean and quarantine new plants to prevent outbreaks.
Caterpillars may have a taste for your plants, but they can't stand the pungent power of garlic. Whip up a garlic solution by mixing 1 tablespoon of molasses, 1 teaspoon of dish soap, and a liter of warm water. Give your plants a regular spray-down with this concoction, and watch those caterpillars turn tail and run.
The Bt spray must be deposited on the leaf surfaces after the eggs have hatched but before the larger larvae move on to pupation sites. You will usually find egg clusters on the undersides of leaves.
To spray, adjust the nozzle to a fine mist and start at the bottom of the plant; point the nozzle up to spray the undersides of the leaves first, working your way up the plant. Make a second pass by spraying the top of the foliage. Again start at the bottom of the plant and work your way up.
Harmful pests such as cutworms and leafminer larvae should be submerged in warm, soapy water to kill them so they don't harm other plants. There are a range of insecticidal soaps that are effective at killing pests. Use a ready-to-use insecticidal soap and spray the worms, repeating the application as needed.
And there's no scientific evidence that Epsom salt will deter slugs, beetles, moles, caterpillars, or any other pest.
Start with “soft” pesticides, such as insecticidal soap, horticultural oil, or neem oil. If those don't help, chemical insecticides are available as a last resort.
Bacillus thuringiensis subspecies kurstaki (Btk) is a microbial insecticide that kills only caterpillars. It's safe to use near bees, beneficial insects, and wildlife. Caterpillars must feed on treated leaves to be affected.
The milkweed plant provides both food and shelter for a caterpillar for approximately two weeks (dependent on temperature) while it eats almost constantly, pausing only to shed its skin. The period between each shedding of the skin, or molt, is called an instar.
As their size increases, so too does the damage they inflict: leaves are often skeletonized, with only the mid-rib left intact. Flowers, fruits and growing tips can also be eaten by larger caterpillars. Some species mine in leaves or bore holes into fruit or stems, making them difficult to detect and control.
A little bit of heat from cayenne pepper goes a long way in the kitchen—and the same goes for your garden. Sprinkling cayenne pepper near the base of plants can discourage some common garden pests that dislike the overwhelming pungency of this pantry staple.
Also, soil that is saturated with a sugar solution can attract harmful micro-organisms that can affect the plant's health. There is no scientific evidence that feeding plants sugar water is conducive to plant health. On the contrary, it can harm your plants and even kill them.
Pepper spray causes irritation of the eyes, skin, and mucus membranes. Inhalation exposures can cause coughing, difficulty breathing, nasal and throat irritation, and a runny nose. Eye exposures can result in pain, redness, watery eyes, difficulty opening the eyes, and sensitivity to light.
