botanical sources. These Natural Pesticides are used to
ward off certain animals and insects, and to kill certain
insects. Oils or chemicals inside these oils are registered as

Botanical Pesticides commonly known as natural pesticides
or organic pesticides are derived from plants those known
for their insecticide or pesticide properties. All the pesticides
derived from plants are not safe for humans, pets and fishes.

humans and non targeted pest and insect too, therefore you
should always read label before using any organic pesticide.

What is Natural Pesticide or Insecticide?

Many plants have a natural protective mechanism which aids
them in resisting and driving of pests. Some plant species
produce substances which repel or poison the insect. The
Neem Tree contains such substances which can be easily
extracted and turned into a natural insecticide. Crushed
seeds or seed kernels are mixed with water and the
resulting solution used to treat the plants.
