Annoying sap-sucking insects like aphids, thrips, spider mites, and whiteflies first damage your plant and eventually kill it.

When using, dilute it with water in the ratio of 8 teaspoons or 35-40 ml in one litre of water. Mist your plants with this solution to coat the insects in an oil solution that stops them from breathing freely and controlling their spread.
Soap spray insecticide
Very similar to the oil spray is a soap spray, which is highly effective in controlling mites, aphids, whiteflies, beetles, and other pests. To make the soap spray, mix 1 1/2 teaspoons of a mild liquid soap with one litre of water, and spray the infected plants generously. Use as required but spray it before or after peak un, spraying in full sun is not beneficial.

Cool the mix and strain and pour into a spray bottle for use. Spray it on the infested plants as and when required, it can be stored for up to two months in a cool dark place. You can also add a few drops of neem oil to improve the effectiveness.
Tomato leaf spray
Tomato plants are part of the nightshade family, and contain alkaloids named "tomatine," which are effective against aphids and other pests. To make tomato leaf spray, chop, or grind 2 cups of fresh tomato leaves and mix it into 1000 ml of water and let steep overnight. Strain out the plant material and spray on the infested plants. It is extremely effective when made fresh and used weekly.
Garlic oil spray
One of the safest and easiest to use insect repellent. Mince 5-6 clove of garlic and let it steep overnight in 3 teaspoons of oil overnight. Strain the oil to remove the garlic pieces and dilute it with 500 ml of water and further add a teaspoon of dish wash liquid and shake well.

This spray works for whiteflies, aphids, and most beetles. Avoid application on sunny days to avoid foliage burn.
Made of sedimentary rocks that are essentially fossilised algae (diatoms), it is one of the most readily available natural insecticides. Amongst its many other use, one is that of a natural insecticide, it works by absorbing the protective waxy coating secreted by insects for protection and then dehydrates them to death. To apply, simply dust the topsoil with it or sprinkle it on the foliage, where it will help control snails and slugs and other crawling insects.
Coffee ground are fatal for ants and other such insects. Caffeine & diterpenes compounds in coffee are highly toxic to insects & helps control bugs, mosquitoes, fruit flies & beetles.

To get rid of aphids in your garden, place chopped up banana peel under the topsoil around the stems of your plants. This prevents the pesky insects and also adds nutrients to the soil. Insects hate light and hence they hide under the leaves.
As a trick, to chase aphids from the underside of leaves, place aluminium foil (polished side up) around the base of your plant covering the topsoil. The sunlight will reflect off of the foil and onto the underside of the leaves, thus driving the critters away.
Not only great for the compost heap, but eggshells also act as fertilizer and pest repellent when added to the bottom of planters before planting. Before sowing vegetable seeds, crush a couple of eggshells, not too finely, and add them to the bottom of the hole. The sharp edges will deter cutworms, and crushed shells around the stem of plants will deter slugs and snails.
Wood ash has multiple uses and not only is it is a free fertilizer, but it’s also an excellent way to get rid of snails & slugs. A ring of wood ash around infested or vulnerable plants helps control them. Crawling on the ash makes slugs and snails lose fluid and slime, so they find it difficult to creep along, hence deterring their movement.
Epsom salt pesticide
Epsom salts can be either be sprinkled around plants or dissolved in water to make a spray. To make a spray, dissolve 30-40 grams of salt in 1 litre of water and spray it on infested plants. It can also be sprinkled on the topsoil, it will deter pests and add magnesium to the soil, which increases the absorption of nutrients by the plants. It is especially effective against slugs and beetles.
