In addition to using biological pest control means, you can also employ the use of row covers, which provide excellent protection during harsh winter months from frost and also menacing pests that damage your garden in the warmer months.
Lastly, you may also want to consider applying Diatomaceous Earth (food grade) on your plants to help fend off the bad bugs as well. This helps by piercing through the bodies of the bad insects and causing death in a short time as the D.E. under a microscope has very sharp edges that can puncture the insects and lead to dehydration and death.
By introducing an eco-system of beneficial insects, coupled with prudent awareness and planning, you can bring about a pest control system into your garden that is completely natural and safe for people, pets and your garden.
