Organic Pest Control:
The Best Plants to Attract Beneficial Insects and Bees

Bee pollinating flowerPesticides — even organic varieties — are not the safest, healthiest or most effective natural pest control options. The addition of certain plants from the list below to your garden or farm will encourage biodiversity and a healthy population of beneficial garden insects that act as Mother Nature’s best organic pest control. Integrated Pest Management (IPM) and sustainable agriculture methodology both rely heavily on the use of plants known to attract beneficial insects that prey on damaging garden pests. According to Dr. Geoff Zehnder, Professor of entomology at Clemson, “If you are going to farm or garden organically, you need to build in attractants for beneficials.”

The first rule to learn is the distinction between the “good guys” and the “bad guys”: Not all pests are a threat to your garden plants, and many of them are actually helpful in fighting off other plant predators. (See Your Garden’s ‘Most Wanted’ Beneficial Insects for more specifics.) As described in a previous MOTHER EARTH NEWS online article, Protect Your Garden with Beneficial Bugs, you can classify the good guys using the three “P’s” system:

“The three ‘P’s’ of beneficial insects are pollinators, predators and parasites. Pollinators, such as honeybees, fertilize flowers, which increases the productivity of food crops ranging from apples to zucchini. Predators, such as lady beetles and soldier bugs, consume pest insects as food. Parasites use pests as nurseries for their young. On any given day, all three ‘P’s’ are feeding on pests or on flower pollen and nectar in a diversified garden. If you recognize these good bugs, it’s easier to appreciate their work and understand why it’s best not to use broad-spectrum herbicides.”

The use of such herbicides and pesticides can be detrimental to the complex relationships between plants, pests and predators — all the more reason why natural insect control works better. Because pesticides, even organic varieties, make no distinction between helpful and hurtful insects, in the end their regular use can have many negative impacts, including the suppression of the soil food web and pollution of waterways. Instead, encouraging the presence of predatory warriors that will defend and protect your garden plants from common  pests is not only an environmentally sound management strategy, it also encourages biodiversity and plant pollination.

Using a strategy known as farmscaping, you can keep your pest population under control by adding plants to attract beneficial insects. A general rule of thumb is to designate between 5 and 10 percent of your garden or farm space to plants that bring in beneficials. An important key is to plant so that there are blooms year-round — the beneficial insects will not stay or survive through a season if no food is available. This continuous-bloom feature in farmscaping has earned the practice the nickname “chocolate box ecology” — your garden or farm will be beautiful year-round with a variety of colorful blooms and humming insects.

The list below is a compilation of the best plants to attract the good guys to your own farm or garden. For more specific planting information, including hardiness zones and bloom dates, you can search for each plant at

Planting broccoli and letting it go to full flower(go to seed so to speak), also attracts bees, as I found out by accident when I did not pull up the plants after harvesting but simply let it remain. Some of the smaller flowering parts matured and I had a constant presence of bees. Beneficial wasps as well as they feast on the worms that like the broccoli leaves. This in turn keeps them off other food crops as the wasp presence, who also check other nearby crops for worms on the leaves, keep the number of worm/caterpillar pests minimized. No, I have never had a wasp or bee bother me while working around them in the garden. I leave them alone, they leave me alone. :)

Thank You for this terrific resource. Just by clicking on a spercies I was interested in linked to the website and a "Recommended" list for my area. Thanks again.

This list is a good start. People can scan down the column and Google plants they are not familiar with. However, I think the publishers may want to address the issue of invasives. Tansy is on the list of perennial flowers, and it is a menace in my region (northern Minnesota). It is taking over hundreds of acres of habitat in and out of town, becoming a vast monocrop which does not support biological diversity. The situation is almost as bad here as it is with kudzu in the south. If you care about Mother Earth (the planet, not the magazine), please research the invasiveness of non-native plants before planting. A good place to start is

As a Master Gardener in Ohio , I can suggest you either contact the local Master Gardeners in your areas for the answers to your questions. Or Google a University that deals with agriculture. We in Ohio, use Ohio State University Extension for our info such as zones for the plants on the list. Kansas State,Iowa State & U of Mich are good resources too.

I totally agree that the broadness of the list makes it confusing, but any list will be misleading compared to what you see in your garden. Look for plants that are buzzing with lots of tiny insects, and you have found a great farmscaping plant for your garden. It's futile to concentrate on specific insects because there are so many, most of them beneficial or neutral. So if you grow something that bees and buzzers can't leave alone, plant more! And remember that native plants attract native insects.

What bugs do they support or repeal? What zones or areas are these beneficial for? What grows beautifully in the mid-west or on the east coast would die immediately in Southern California. While it is a nice list, I have to pick through the list to see what will grow or die.

I agree with the 6-5-10 comment. Information is not very helpful and not at all what I expected. Seems like you are either lucky or not.

6/5/2010 10:51:54 PM
This list is not what I expected from ME at all. No zones are listed, no list of which insects it mostly attracts and what insects they eat! What a shame.

6/4/2010 2:28:12 PM
Wonderful info! Thank you! Question: Is it possible to find out for each plant listed, what specific beneficials (obviously bees) are attracted to it and what bad guys they help control? I am especially interested in knowing what specific flowers/weeds/plants best attract predatory wasps who love to eat caterpillars and inchworms, etc.... Thanks!
