Lacewings are intense consumers of aphids, and their larvae eat aphids and other varieties of insect pests. They are generally attracted by “composite” flowers, like yarrow, goldenrod, black-eyed susan’s and asters.
Hover-flies are intense consumers of aphids and the larva of hover-flies eats aphids and other insect pests. Like the Lacewings, they are attracted to “composite” flowers, such as yarrow, goldenrod, black-eyed susan’s and asters. Seeds for these flowers are available online, or at most garden centers.
- Praying Mantis
These large insects have hunger for many garden pests. Praying mantis eggs are deployed in the garden where they hatch and rapidly grow to adult size.
Nematodes are also effective against beetles, cutworms, and root weevil larvae. Nematodes do not cause harm to humans and pets. Nematode eggs are microscopic (very small) and is available in the form of a small sponge which has million of eggs. These are combined with water and applied to the soil, where they hatch and work.
‘Mini – Insectary’ garden can also be established nearby to a small garden plot of flowering plants designed to attract and withhold beneficial insects.
