              Pros
              • Eliminate insects, fungi, and mites
              • Organic oil
              • Easy to use for novice
              • Not toxic to good insects
              Cons
              • Can’t kill ants
              • May hurt the raspberry plant and begonia

              The Neem oil kills aphids, whiteflies, black spots, pests, powdery mildew, and also controls spider mites.

              I mostly used this bottle to treat tomato fruit worms and stink bugs. The whole corner was attacked viciously resulting in distorted leaves and fruit.

              The product is produced for use in organic gardening. It is a recipe for oil extracted from the neem tree. Besides putting down insect pests, the formula also works on fungi.

              Basically, you just need to spray the liquid on a regular basis. I usually mix roughly 2 tablespoons of Neem oil to one tablespoon of sal suds, a kind of organic soap.

              One thing to notice is that this thing won’t knock down ants. But the ants will leave your plants alone.

              In my experience, you should apply the oil early in the morning so that it won’t hurt bees

              • Use on non-edible plants only

              I bought this spray to treat Japanese beetles eating roses in my grandma's home. She had been pissed off at the damaged rosebuds and ugly leaves.

              The concern grew bigger when these little “bad boys” kept coming back before I used this spray. BioAdvanced is made to focus on Japanese beetles, aphids, whiteflies, spider mites, leafminers, and more.

              Thus it worked perfectly on roses and other plants like hibiscus, iris, ornamentals, shrubs, and so on. The effect lasted around 27 days and I noticed there were no those crawling creatures appearing again.

              I also applied this BioAdvanced spray to treat fungus on my vines. No doubt the miracle also happened. It controlled the disease and cured black spots on the leaves. And the result looked gorgeous.

              The spray can solve problems with mites as well. If you ever need to kill spider mites on contact, there you have the solution ready.

              My granny ended up storing 5 bottles of this spray. She knows the effects and needs it again for her beautiful rose garden.

              Best For Plant Bugs: Safer Brand 5110-6 Insect Killing Soap

              Safer Brand 5110-6 Insect Killing Soap
              Safer Brand 5110-6 Insect Killing Soap
              8Good
              Pros
              • Economical
              • Plant friendly
              • Fast effect
              • Only kill harmful bugs
              Cons
              • May not kill aphids
              • Doesn’t work well on soil gnats

              This insect killer from Safer is actually a recommendation of my neighbor to treat plant bugs in general while saving my budget.

              It is said to kill psyllids, sawfly larvae, soft scales, spider mites, squash bugs, blossom thrips, and whiteflies. Indeed, it worked on my plants after the first two applications.

              The only I’m unsure is if this product is any safe for edible plants but I really expect it would because the label says it’s just seaweed extract.

              This insecticidal soap basically contains compounds that penetrate and dehydrate bugs’ bodies. It only targets harmful insects and leaves beneficial species alone.

              In my case, mealybugs were the major concern of plants on my patio. I could have used Neem oil, but I wanted to try this suggestion. It did reduce the population of those insects however for aphids, I still saw them crawling. But I think it wasn’t the solution that didn’t work but just new aphids kept coming back. I’ll keep spraying and see how it goes.

              When using the solution, I sprayed from top to bottom. There was a smell but the odor is acceptable, not as bad as most pesticides I knew before those in this list.

              • Control more than 50 harmful pests
              • Work on low concentration

              Cons
              • Not 100% organic
              • Not an instant kill

              This product has a strong polymer as a part of the formula that keeps the active ingredient in place. It lasts longer outdoor since it takes longer to erode and lose effectiveness. That said, it has a residual of up to 90 days. So, I recommending spraying every 3 months for continual control.

              This Suspend controls many different species of insects. As far as I know, the solution can control ants, bed bugs, mosquitoes, spider mites, and more than 40 other nuisance pests. It’s safe for use both indoor and outdoor.

              It’s important to know that due to the nature of this formula, the Suspend Polyzone can leave behind a visible film when applied, especially indoors.

              You can mix the Suspend at a rate of .25 to 1.5 fluid ounces per gallon of water depending on the level of infestation and the targeted pests.

              At home, I use this solution around structures. Mostly, I apply around fences and brick structure as the polymer coating on active ingredient helps it stick to the surface without absorbing into the material.

              How To Choose The Best Insecticides For Vegetable Garden?

              Insecticides come in a variety to focus on treating well certain types of pests. This is because, in one vegetable garden, you are likely dealing with that feed on, not only veggies, but also fruits, ornamentals, houseplants, and on and on.

              Therefore, it’s important to know which kind of pesticide to suit your demand.

              Basically, an insecticide is a solution made to kill insects. It’s a form of pesticide that works effectively in controlling and killing insects.

              However, there is more than one kind of insecticides.

              Botanical

              This kind is more familiar with organic gardeners for its nature. Botanical insecticides contain no toxic chemicals. Mostly, the pesticide is an extraction from plants and minerals which are safe for humans but harmful to insects.

              The naturally-occurring chemicals of botanical pesticides usually come in forms of spinosad, neem oil, or Pyrethrin. In which:

              • Spinosad: a mixture of Spinosyn A and B made from a soil bacterium. The substance highly affects insects without harming the environment. Spinosad attacks the nerve system of bugs then paralyze them in 1 or 2 days.

              • Neem oil: a naturally occurring pesticide found in Neem trees, majorly in the fruit and seeds. Neem oil contains Azadirachtin, an active component that repels and eliminates pests. It’s also very effective in controlling the growth of eggs and larva.

              • Pyrethrin: extraction from the flowers of the pyrethrum chrysanthemum plant. It has an effect on a wide range of insects. The insecticide is friendly to organic gardening with a low toxicity level. Besides, pyrethrin is known to cast an instant knock-down as soon as it comes to contact. However, even with little use of Piperonyl Butoxide (PBO), humans may not find any interest in consuming plants sprayed with it. In this case, Neem oil is a more preferable choice.

              Inorganic

              You probably need to be aware that using inorganic insecticides is killing the earth. But it’s worth knowing a few things about this type.

              Inorganic insecticides consist of heavy metal and arsenic compounds that are high in performance. There are four types of insecticide.

              • Systematic: Usually applied to the soil. Once the roots absorb the substance, it moves the insecticide up to the leaves, fruits, twigs, and branches to prevents pests from eating them.

              • Ingested: A sort of poison attractive to rodents and cockroaches. Once the rats or bugs consume, they will come to death.

              • Contact: Available in sprays, liquid vaporizers, repellents, or coils to eradicate insects. You might have used this type to disinfect your home.

              • Herbicides: Used to destroy the damaged parts of plants. Herbicides include fungicides; mostly popular in destroying weeds and fungi.

              How do I keep bugs out of my vegetable garden?

              There is a number of ways you can do to control bugs in your veggie garden. Spraying insecticide is one way, another is to use home-made solutions. But if you mean is there is any way to manage those freeloaders without applying any chemical; yes, there are some:

              • Fertilize and water regularly

              • Plant herbs and flowers around the plants

              • Attract predators

              • Clean weeds

              • Spray vinegar

              • Remove infested plants

              • Place pheromone traps

              What is a natural pesticide for vegetable gardens?

              Neem oil is the most popular natural pesticide for your greens. Besides, you can use spinosad - a type of naturally occurring bacteria, or iron phosphate that kills snail and slugs.

              I also found another organic thing you can use is Diatomaceous Earth. It’s a very fine powder that scrapes bellies of any insect that crosses over it.

              What's eating my plants at night?

              Moths, beetles, mosquitos, crickets, snails, and slugs are among harmful-for-plants creatures that are active at night.

              Will vinegar kill bugs on plants?

              Yes. White vinegar is an active bug repellent when combined with other ingredients in a soap spray. You can apply the mixture on plants in the trees and shrubs, the underside of leaves to allow direct contact.

              Conclusion

              The best insecticide for a vegetable garden is a vital solution to have in your storage to control the health of your harvest.

              Using these sprays is not at all a problem even you are new. Just follow the instruction on the label to get the right mixture. Always prepare spray bottles or dispensers. Remember, when handling this liquid, you should have gloves on.
