These bees are really trashing my roses.
Sevin Concentrate is labeled for treating leafcutting bees and other listed bee species. Keep in mind that Sevin is only a contact kill and will not offer residual protection. Repeat applications are necessary only if there are signs of renewed insect activity. "This product is also highly toxic to honeybees and other bees. Do not apply to plants in bloom." Almost all insecticides are toxic to bees as they are non-selective. You can help limit any effect to bees by being careful not to apply the insecticides when bees are actively foraging in the area.
