What is an organic insecticide for yellow squash?

Answer 1

I'm assuming that you have squash bugs. you can use pyrethrins (made from mum flowers) insecticidal soap, rotinone, also rotate your plant every year using the three year rule(don't plant in same spot for three years) this goes for all veggies.

Answer 2

[1] The choice of insecticide depends upon the bug, and upon whether there's a preference for organic or synthetic controls. [2] Both organic and synthetic controls can leave residues, which are supposed to disappear with time. [3] However, most bug problems can be solved by the environmentally-friendly organic solutions of botanicals such as pyrethrin; insecticidal soaps, which can be homemade or store-bought; and oils such as horticultural and neem.
