These methods provide effective, non-chemical options for controlling blister beetles in gardens and farms.

• Handpicking: Remove beetles by hand, wearing gloves to avoid irritation.

• Soapy water: Spray a mixture of mild soap and water on affected plants to suffocate beetles.

• Neem oil: Apply diluted neem oil to deter and disrupt beetle activity.

• Physical barriers: Use row covers or netting to protect plants from beetle access.

• Companion planting: Plant repellent species like marigolds near vulnerable crops.

I've attached a Blister Beetle fact sheet and Horticultural oils if you want more information.  

Happy gardening,
