Many of the insects in your garden are not pests—they’re a protective part of an ecosystem that helps your garden be healthy and productive.

Beneficial insects support your garden in three key ways:
Predators control pests
Parasitoids stop pests before they spread
Pollinators make plants produce food
Together, they create a balanced system that reduces the need for sprays and keeps your garden healthier over time. A successful garden doesn’t eliminate all insects.
It feeds, supports and protects the beneficial ones.
How to Attract and Support Beneficial Insects
Beneficial insects stay where their needs are met.
Plant for Continuous Food
Many beneficial insects eat pests only in their larvae stage. When they grow into adults, they rely on nectar and pollen. Plant a variety of flowers that bloom from early spring through fall.
Provide Real Habitat
Beneficial insects don’t just live on plants—they live in your garden.
They take cover under mulch and leaf litter. Allow them some stems and natural debris
Allow a few undisturbed corners
Limit or Avoid Insecticides and Pesticides
Broad-spectrum insecticides kill beneficial insects along with pests.
Reducing sprays helps your garden develop a self-regulating system.
Accept Some Pest Presence
No pests = no predators
A small pest population keeps beneficial insects active.
Sometimes its difficult to tell the good guys from the bad guys:

Final Takeaway
Beneficial insects are your garden’s built-in defense system.
