- These products consist of, or are derived from, bacteria and other microbes.
- Microbe-based products, like Bacillus thuringiensis and spinosad, are generally safe for people and selective for pests.
- Please read and follow the label.
Insecticide soaps and horticultural oils
- These products kill smaller, soft-bodies arthropods like mites, aphids and scales. They only kill when sprayed directly on the pest.
- Horticultural oils are sometimes called dormant oil, Volck oil, summer oils or ultrafine spray oils.
- Store bought versions of these products are generally safer to plants (read the label)
- Soaps and oils are among the cheapest and safest pesticides for the garden.
Botanical (plant-based) insecticides
- Plants make their own insecticides. Check the labels of these products to compare toxicity. Just because a pesticide comes from a plant doesn't mean it's safe for people.
- Botanical pesticides generally breakdown quickly when exposed to sunlight, air and water. This keeps them relatively safe for many beneficial insects.
- Look for products containing pyrethrins, neem extracts, mint oils and citrus oils.
If you decide to purchase any of these products, please read and follow the label. Remember that the label is the law. As you are out in your garden please be on the lookout for beneficial insects before your spray. They are our friends in the garden and are doing us a huge favor! Until next time, happy gardening!
