Is there a Natural recipe to get rid of bugs on plants?

Brew a pot of coffee and let it cool. Pour into spray bottle and spray on plants. It freaks out the bugs and gives your plants (if they are the type that need it) a tiny shot of nitrogen.

I have seen a product Aquablast Bug Spray.

It contains pyrethrins and can be used on edible crops and ornamental garden plants. It is a ready to use spray and controls aphids, blackflies, greenflies, caterpillars and whiteflies on garden flowers, fruit ad vegetables.

Alternatively there is a product called OA2KI which is based from plant extracts and works against the majority of crawling and flying insects.

Use NEEM OIL. It is an inexpensive organic concentrated oil. Though it smells slightly of garlic & onions, it works wonders for controlling a plethora of insects.

Soap sprays are the simplest and cheapest way to get rid of aphids and other insect pests on plants. Insects breathe through pores in their exoskeletons, and soap surfactants cover these pores, suffocating the insects. For small infestations, fill a 1 quart hand pump sprayer halfway with warm water, and add 3-4 drops of dish soap. Shake the bottle a few times to mix, fill it the rest of the way, then spray the insects. Make sure you thoroughly coat the undersides of the leaves and all visible pest insects. For larger infestations, use a gallon sprayer that hasn't been used for chemicals before, and add 1 tsp dish soap to 1 gallon of water. Soap sprays kill existing insects and insect eggs, but are not persistent and have to be re-applied every few days to eliminate infestations.
