Pest control is top of mind for any farmer or gardener, whether they're growing in a greenhouse or the great outdoors. However, pesticides and insecticides are indiscriminately harsh and often wind up killing pollinators that help plants thrive. Luckily, you can always rely on nature's pesticide: beneficial insects.
The importance of beneficial insects cannot be overstated. These helpful garden insects clear out pests without damaging the plants. It's a natural means to take care of your plants and get rid of pesky insects without harming pollinators or the plants themselves. In using beneficial insects, you can monitor the numbers of aphids, whiteflies, mealy bugs, leaf miners, and many other common kinds of greenhouse pests to ensure that your plants grow up strong and undisturbed.
Just like all species, garden insects are broken into two groups: generalists and specialists. A specialist bug will prey on one or a few different kinds of pests, while a generalist will eat a broader spectrum of prey, including other beneficial insects. When choosing a generalist species, it's important to keep an eye on their population size so they don't begin eating your other beneficial garden insects as well.
There are a few different kinds of beneficial insects that will be most helpful to your greenhouse environment. Check out the list of beneficial insects below to learn more about these helpful hunters!
Having a garden or greenhouse full of delicious pests isn't always enough to attract the beneficial insects needed to combat them. Many beneficial insects also need the carbohydrates found in nectar and pollen in order to reproduce — others are only pest eaters in their larval state and grow into a nectar or pollen-based diet. The flowering plants listed below are excellent sources of nectar that will support your predatory insects and pollinators alike (and make your greenhouse or garden that much prettier).
