Searching for safe alternatives to synthetic pesticides is crucial for protecting bee populations. Spinosad, an organic pesticide, poses a risk to bees due to its toxicity at low levels. However, its toxicity decreases significantly once spray residues have dried. To minimize bee exposure, applying spinosad at night when drying conditions are optimal is recommended.
Relative to other organic pesticides, low levels of spinosad can be toxic to bees. Spinosad is much less toxic after spray residues have dried (Mayes et al. 2003). Applying at night, when conditions allow for residues to dry, can help reduce bee exposure.
Are organic pesticides safe for bees?
Unfortunately, however, pesticides allowed for use in organic agriculture can cause harm to bees and beneficial insects.

Is Sevin spray bad for bees?
The high toxicity of Sevin to honeybees, Apis mellifera L., has been well documented (2, 4, 5, 6), and Johansen (3) rates it as the number one bee-killing chemical.
What kills grasshoppers but not bees?
Safer® BioNeem contains azadirachtin, the key insecticidal ingredient found in neem oil. This concentrated spray is approved for organic use and offers multiple modes of action, making it virtually impossible for pest resistance to develop. Best of all, it’s non-toxic to honey bees and many other beneficial insects.
Is garlic spray safe for bees?
Use Garlic Spray or Powder It isn’t recommended that these are used against a beehive or directly on a bee because garlic can be toxic to bees and bee larvae.
What insecticide will not harm bees?
Etoxazole is a selective miticide effective against most plant-feeding mites, but fairly safe for most predatory insects and mites. Etoxazole is practically nontoxic to adult honey bees.
How do you get rid of grasshoppers without killing bees?
Safer® BioNeem contains azadirachtin, the key insecticidal ingredient found in neem oil. This concentrated spray is approved for organic use and offers multiple modes of action, making it virtually impossible for pest resistance to develop. Best of all, it’s non-toxic to honey bees and many other beneficial insects.
What insecticide is safe for pollinators?
Acequinocyl is considered nontoxic to bees and can be applied at any time. Since acequinocyl is selective for mites, other pollinators and natural enemies should not be affected.
What can I use instead of neonicotinoids?
“But imidacloprid controls many other pests not covered by this product. We will be looking further to find other alternatives.” ArborSystems’ Boxer Insecticide-Miticide is an alternative to neonics for tree care. It is used to control EAB and 30 other insect pests.
What is a safe alternative to Sevin?
Another insecticide you can use instead is Bt (Bacillus thuringiensis). This insecticide, sometimes sold as Dipel, can be sprayed on the leaves in the area where they are feeding. The nice thing about Bt is it won’t harm other insects that might help you by eating the caterpillars.

In conclusion, it is crucial for farmers and gardeners to be aware of the potential harm certain organic pesticides can pose to bees. While organic pesticides are generally considered safer for the environment, some can still have negative effects on bee populations. By choosing organic pesticides carefully, implementing alternative pest control methods, and promoting bee-friendly practices, it is possible to strike a balance between protecting crops and preserving bee health. Collaboration between researchers, policymakers, and agricultural stakeholders is essential to further explore the impact of organic pesticides on bees and develop sustainable practices that prioritize both food production and pollinator conservation.
