Beneficial insects are the unsung heroes in sustainable gardening, accounting for more than 95% of the bugs you find in your landscape. Helping these little allies means you’re supporting ecosystem balance, increasing plant health, and supporting the reproduction of flowering plants and the production of fruits, vege’s and seeds. Oh, and you’ll have fewer mosquitoes ruining your BBQ.
These good guys include predators, like lady beetles, dragonflies and spiders; parasitoids, like certain wasps and midges that lay eggs on or inside a host, playing the long game in pest control; decomposers, like earthworms that break down organic matter, turning trash into treasure for the soil; and pollinators – A-listers, like bees and butterflies, and the underappreciated, like hover flies.
How can I benefit them?
Plan for continual blooms
Plant a variety of flowers that bloom at different times of the year to provide continual sources of nectar and pollen.
Plant Native
Not every plant is created equal. Native plants provide ALOT more in the way of food and shelter.
Create Habitat Diversity
Design your garden to include various habitats, such as open spaces, dense vegetation, and water features.
Provide Water Sources
Insects need a drink, too – especially during hot weather. Here’s how.
Avoid Pesticides
Minimize or eliminate chemical pesticides – they don’t discriminate between good and bad bugs. If pesticides are necessary, opt for targeted and less harmful options and follow directions.
Leave Some "Messiness"
Allow some areas of your garden to be a bit wild or untidy. Fallen leaves, decaying plant matter, and small piles of rocks or wood can provide shelter and breeding sites.
Avoid Disturbing Soil Too Much
Excessive tilling and soil disturbance can disrupt the habitats of beneficial insects, especially those living in or near the soil. Adopt no-till or reduced-till gardening practices.
Introduce Beneficial Insects
Consider releasing beneficial insects, such as ladybugs, into your garden to enhance natural pest control. This is especially useful when dealing with specific pest issues.
Provide Food for Predators
Plant specific crops or flowers that attract prey for predatory insects. For instance, planting dill, fennel, or parsley can attract insects that serve as food for predatory wasps.
