What other raw materials can we use to make a environment-friendly pesticides?
Answer:
There are several things that are environmentally-friendly pesticides. Botanical pyrethrins, which come from flowers such as chrysanthemums and marigolds, are one example.

Diatomaceous earth is earth which used to contain live diatoms. Diatoms are one-celled life forms which have a high percentage of silica. The silica is left behind even though the live diatoms have died.Diatomaceous earth can be used to control insect pests in the house (such as ants.) When spread along their trails, the sharp silica deposits from the dried out diatoms cut open the insect's body and kills it.
