Best Insecticides for Your Vegetable Garden

All vegetables are tender and nutritious, and they attract a wide range of insects. It is frustrating to see your tender vegetable plants badly infested with creepy caterpillars, thrips, aphids, fruit flies, and other insects that are happily eating them. Insects usually attack vegetable plants that are unhealthy or possess a weak defense system.

This article will summarize the accurate information about the best insecticides sprays and dust to control pests in your vegetable gardens.


Insecticides are chemical products applied either in dust or liquid form on the affected crops to control insect infestations. Powder forms are dusted directly on to the infected plants, while concentrated insecticides require dilution before applying.

Spraying of insecticide is preferred over dusting because it provides more uniform coverage, and this way, it is easier to treat the tops and undersides of plant leaves. They can also be applied as soil drenching to kill the soil insects.

Types of Insecticides

There are two types of insecticides based on the chemical nature of the product:

Inorganic Insecticides

Inorganic insecticides are human or artificially made from synthetic formulas (like carbamates or pyrethroids). They can also be manufactured from heavy metals and arsenic compounds. These types of insecticides are highly effective against insect pests, but proper care should be taken while applying them to your vegetable garden. 

Organic Insecticides

These are made from plant oils and animals or plant-derived fatty acids. They are environmentally friendly and cause no harm to your vegetable crops. The example of these types of insecticides includes insecticidal soaps, and nicotine, etc.
