Tips for spraying insect pests with safe, organic bug killers.
No matter how carefully you control growing conditions with healthy soil and proper watering, no matter how well-thought out your integrated pest management system, no matter how lucky you’ve been in the past, sometimes a pest problem arises in your garden that requires spraying the little buggers. What you spray and how you spray can make all the difference.
Most organic gardeners prefer sprays that break down quickly in the environment or opt for home made remedies that make the plant unpalatable or difficult for the insects to populate. These sprays are often made of garlic, cayenne and other peppers, as well as strong scented herbs. The idea is to confuse the insect’s sense of smell (which is often located in their feet) and make them think they are where they don’t want to be. They’re often the organic gardeners first line of defense when pests are spotted.
The second line? Citrus oils, diatomaceous earth, even compost tea are known to work on some insects. Then there are the manufactured products you can make at home that suffocate the pest or make their environment inhospitable. These include soap solutions, often made at home and horticultural oils.

Bleach is used especially in greenhouses to disinfect and control diseases. These ingredients are toxic unless diluted and dangerous if not handled correctly. (more…)
