Use Biopesticides made at home, following are their formulations:
Oil Mixture
1 cup cooking oil ( i.e. canola or vegetable )
1 tablespoon liquid dishwashing soap
Use 2 ½ teaspoons of this mixture in 1 cup of water
Spray on the surface and underside of leaves to coat insects in various stages of development.
This mixture is especially good with eggs and immature bugs. Be careful on the type of liquid soap you choose.
Soap Mixture
A few teaspoons of liquid dishwashing soap
1 gallon of water
Spray on the surface and underside of infested foliage. The soap acts to paralyze insects, which prevents them from feeding. The pests eventually die of starvation. For heavy infestations spray every 2 to 3 days for 2 weeks.
This is a very generic mixture that can fight off most any insects. Make sure to use a light liquid soap here as well to ensure not to kill your plants.
Garlic/Pepper Mixture
1/2 cup hot peppers of your choice
1/2 cup garlic cloves ( onions will also do )
2 cups water
Steep this mixture for 24 hours. An easy method for steeping the tea is to combine the ingredients in a clear glass jar, seal, and set in a sunny location. Strain and spray onto foliage.
This is another good general mixture that will fight off most bugs.
