Beneficial Insect Habitat
Plants that provide shelter and food for predatory insects that control pests
What Are Beneficial Insect Habitat?
Beneficial insects - ladybugs, lacewings, parasitic wasps, ground beetles, hoverflies, and predatory bugs - are your garden's pest control team. These plants provide the nectar, pollen, shelter, and overwintering sites that beneficial insects need to thrive. A diverse planting creates a balanced ecosystem where pest populations are naturally regulated.
Benefits
- Natural pest control reduces or eliminates need for pesticides
- Balanced insect populations prevent pest outbreaks
- Many beneficial insect plants also attract pollinators
- Creates habitat complexity and biodiversity
- Supports complete life cycles of beneficial species

Implementation Tips
Plant diverse habitat plants throughout the garden, not just at edges
Include plants with different flower structures (umbels, daisies, tubes)
Leave some plant debris and mulch for overwintering beneficial insects
Avoid broad-spectrum pesticides that kill beneficial and pest insects alike
Accept some pest damage - it's food for beneficial insects
Plant early-blooming flowers to support beneficials before pests emerge
Provide water sources and bare ground for habitat diversity
