Beneficial insects pollinate plants, prey on garden pests, or develop on pest insects as parasites. To encourage them, offer regionally suitable flowers, nesting and shelter habitat, and avoid unnecessary exposure to pesticides. “Beneficial” is not a guarantee: an insect’s role depends on its species and life stage, and a garden’s natural enemies do not promise pest-free plants.
What are beneficial insects?
Beneficial insects are insects that provide a useful service in a particular setting. Some move pollen between flowers; predators eat other insects; and some parasitoid wasps lay eggs in or on a host insect, with their developing young attacking that host. These services can support plant reproduction and natural pest management, but they are not interchangeable.
A common name alone does not establish whether an insect is helpful. Lady beetles include both predators and plant pests, and an insect’s role can change as it develops. The examples below are useful groups to recognize, not a fixed scientific roster. For an overview of garden natural enemies, see UC IPM’s guide to beneficial predators and Colorado State Extension’s guide to beneficial insects and other arthropods.
Which insects eat aphids?
Several of these groups include predators of aphids, particularly lady beetles, green lacewings, and the larvae of many hoverflies. Their presence can contribute to natural pest control, but it does not ensure that aphids will disappear. Soldier beetles and ground beetles are also predators of other insects; their diets and useful roles vary.

Lady beetles (ladybugs)
Many lady beetles prey on aphids and other pests. But the name covers different species: Colorado State Extension identifies the Mexican bean beetle as a plant pest. Identify the insect before treating every spotted beetle as an ally or a problem.
Green lacewings
Green lacewing larvae prey on soft-bodied pests such as aphids. Adults use nectar and pollen, so flowering plants can support a different life stage from the one doing the predation.
Hoverflies (syrphid or flower flies)
Adult hoverflies visit flowers for pollen and nectar, while larvae of many species prey on aphids. Adults can look like bees, so appearance alone can mislead; hoverflies are flies, not bees.

Ground beetles
Ground beetles hunt at soil level and can feed on pest insects and soil-dwelling stages. Ground cover, mulch, and sheltered spaces give these ground-dwelling predators places to live.
Soldier beetles
UC IPM includes soldier beetles among general predator groups. Their role should not be assumed to be identical across species or life stages.
Which beneficial insects pollinate flowers?
Native bees
Native bees are important pollinators, and many species nest alone rather than in large colonies. Flowering plants provide food; appropriate nesting habitat can help support the species that live in your area. Plant and nesting choices should be tailored to local conditions. Guidance from Iowa State Extension discusses gardening for both pollinators and beneficial insects.

Butterflies and moths
Adult butterflies and moths visit flowers and can pollinate them. Their caterpillars feed on plants, however, so supporting these insects may mean accepting some larval feeding. Choose plants with local species and your garden’s conditions in mind rather than expecting every plant to remain untouched.
Flower-visiting predators
Pollination and pest control can overlap. Adult hoverflies and green lacewings use flowers for pollen or nectar, while larvae of many hoverflies and green lacewings hunt pests. A flower patch can therefore provide food to adults whose young perform a different service.

Some parasitic wasp species lay eggs in or on host insects. The wasps’ developing young attack the host. Many of these wasps are tiny and do not pose the stinging risk people commonly associate with social wasps. The word “wasp” alone is not enough to determine an insect’s behavior; the role described here applies to some species, not all wasps.

How do I attract beneficial insects to my garden?
Choose flowers for your region and growing conditions
Plant a diversity of flowering plants with different flower forms and bloom periods. Flowers can supply pollen and nectar to pollinators and to the adult stages of some natural enemies. Select species suited to your region, soil, light, and available space instead of relying on one universal plant list. Flowering herbs and plants in the carrot family appear in extension recommendations, but some suggested plants can also attract pests; Penn State Extension advises considering where to place them. See Penn State’s guidance on attracting beneficial insects.
Provide shelter and nesting habitat as well as food
Flowers are only part of the habitat. Ground cover, leaf litter or other plant material, sheltered areas near the ground, and some bare soil can benefit different organisms and life stages. The right mix depends on which insects you want to support: many native bees need nesting places, while ground beetles need habitat at soil level. The National Pesticide Information Center’s overview of beneficial insects also describes the value of habitat.
Limit pesticide exposure to natural enemies
Pesticides can harm predators as well as target pests. UC IPM recommends protecting beneficial predators by avoiding pesticides that kill them and providing plants with pollen, nectar, and shelter. If treatment is necessary, choose advice specific to the crop, pest, and product label, and account for pollinator exposure. Do not assume a treatment is harmless to beneficial insects simply because it is used in a garden.

Encourage resident insects before buying releases
For home gardens, Penn State Extension favors encouraging beneficial insects already present over purchasing and releasing them. Commercial beneficial insects are increasingly used in greenhouses, but a release is not a substitute for suitable food and habitat in a home landscape.
Should I buy ladybugs for my garden?
For a home garden, start by encouraging resident natural enemies rather than buying lady beetles. A release does not replace flowers, shelter, or appropriate pest management, and the general advice to support local populations is more reliable than assuming purchased insects will solve a pest problem. First confirm the pest and identify the beetles you see; not every lady beetle is beneficial. Penn State Extension discusses the home-garden approach in its beneficial-insect guidance.
Are praying mantises good garden pest control?
Not reliably as a targeted solution. Oregon State Extension notes that praying mantises also eat beneficial insects and provide limited control of common garden pests. If the goal is to support natural pest management, a varied habitat for resident predators and pollinators is a better-supported approach than relying on mantises to selectively remove pests. See Oregon State Extension’s guidance on encouraging beneficial insects.
