Fact vs. Fiction: Myths About Beneficial Insects
Jul 21, 2025
In the world of agriculture and horticulture, beneficial insects are essential allies in supporting plant health and managing biological challenges. However, many myths and misunderstandings still surround their use. In this article, we’ll debunk some of the most common misconceptions and offer practical guidance for using beneficial insects effectively across all types of growing environments. From the myth that you can’t water after applying sachets to the belief that beneficials only work in warm climates, we’ll separate fact from fiction and help you make the most of these natural solutions.
Myth 1: You Can't Water Your Plants When You've Applied Sachets
Fiction: Some growers worry that watering after applying sachets will wash away the insects or reduce their effectiveness.
Fact: Sachets are designed to withstand watering and gradually release beneficial insects over time. Watering is not only safe—it can actually help create a more favorable microclimate for insect emergence. Just avoid high-pressure watering directly on the sachets. Low to medium pressure irrigation around the sachets is ideal.
Myth 2: Beneficial Insects Are Only Effective in Organic Gardens
Fiction: There’s a belief that beneficial insects only work in organic production and are ineffective in conventional systems.
Fact: Beneficial insects are a valuable tool in organic systems, but they’re equally effective in conventional operations, indoor environments, and hobby setups. The key is compatibility—avoid broad-spectrum products and choose inputs that support biological solutions. Many beneficial insects can function well in low-residue environments when managed thoughtfully. If you're unsure whether beneficials can be used alongside your current spray program or inputs, reach out to our live chat—we’re here to help you find the right fit for your system.
Myth 3: Beneficial Insects Will Overrun Your Garden
Fiction: Some worry that releasing beneficial insects will lead to an overpopulation that causes new problems.
Fact: Beneficial insects are self-regulating. Their populations naturally adjust based on the availability of their target organisms. Once the biological challenge is under control, their numbers decline. These insects are highly specific in their role and do not damage crops—unlike leaf-chewing or sap-feeding organisms. Think of them all like ladybugs: helpful, not harmful.
Myth 4: Beneficial Insects Are Only Effective in Warm Climates
Fiction: Some assume beneficial insects can’t survive or function in cooler environments.
Fact: Many beneficial species are adapted to a wide range of climates. Whether you’re growing in a coastal greenhouse or a high-altitude tunnel, there are species suited to your conditions. The key is selecting the right insect for your environment and crop system. If you're unsure of what beneficials to use in your particular climate, please reach out our live chat - we'll help you find the optimal solution.
Myth 5: Beneficial Insects Are Expensive and Difficult to Obtain
Fiction: Some growers believe beneficial insects are too costly or impractical to use consistently
Fact: While some species may carry a higher upfront cost, many beneficial insects are designed for repeated, low-cost application—making them a smart, scalable solution for growers of all sizes. Rather than waiting for a problem to escalate and paying for one or more high-pressure chemical interventions, investing early in beneficial insects allows you to stay ahead of issues with low-pressure, preventative inputs.
Think of beneficial insects as a proactive investment in plant health. When used consistently, they help maintain balance, reduce the need for reactive treatments, and support long-term crop resilience. This approach not only protects your plants—it protects your bottom line.

Myth 6: Beneficial Insects Work Instantly
Fiction: There’s an expectation that beneficial insects will provide immediate results.
Fact: Beneficial insects need time to establish and become active. It may take several days or weeks before you see a noticeable shift in the crop environment. Regular scouting and patience are key to evaluating their impact.
Myth 7: Some Beneficial Insects Are Harmful to Humans
Fiction: Some growers worry that beneficial insects might sting or be harmful to humans.
Fact: The species used in crop production are harmless to humans. Even parasitic wasps, which may sound intimidating, are completely safe.
Myth 8: Beneficial Insects Are a One-Time Solution
Fiction: Some believe that a single release of beneficial insects will solve the problem permanently.
Fact: Beneficial insects are part of a broader biological strategy. Ongoing monitoring, environmental support, and periodic releases may be necessary to maintain balance. Integrating biologicals with cultural and mechanical practices leads to more sustainable outcomes.
Tips for Using Beneficial Insects Effectively
Choose the Right Species: Match the insect to the specific issue and your growing environment.
Support Their Habitat: Use banker plants, avoid disruptive inputs, and maintain humidity where needed.
Monitor Regularly: Use scouting tools and visual inspections to track both the problem and the solution.
Be Patient: Allow time for beneficials to establish and do their work.
Stay Informed: Learn about the insects you’re using and consult with your supplier for best practices.
Conclusion
Beneficial insects are a powerful tool for growers of all types. By understanding and overcoming common myths, you can integrate them confidently into your growing strategy. Whether you’re managing a greenhouse, nursery, or indoor facility, these natural allies can help you maintain healthy crops and reduce reliance on chemical inputs. Choose the right species, support their environment, and give them time to work—and you’ll see the benefits unfold.
