Why are beneficial insects preferred in sustainable gardening?

Beneficial insects are preferred in sustainable gardening primarily because they help control pest populations without the use of chemical pesticides. This natural pest management approach promotes a healthier ecosystem, reduces chemical runoff, and helps maintain soil and plant health. Beneficial insects, such as ladybugs, lacewings, and parasitic wasps, feed on common garden pests, effectively keeping their populations in check.

Using beneficial insects aligns with the principles of sustainable gardening by fostering biodiversity and creating a balanced environment where plants can thrive without the detrimental effects of synthetic chemicals. In contrast to the other options, which either do not relate to the beneficial role of insects in gardening or suggest negative impacts, the use of beneficial insects stands out as an eco-friendly and practical solution in the pursuit of sustainable practices. This method not only ensures effective pest control but also supports the overall health of the garden ecosystem.
