Place dormant wasp lures or old nest scans near entry points, seems to deter re-nesting. Might just confuse them psychologically.
@HiveHacker That’s wild. I guess once they find good shelter and protection, location becomes king, even if the exact spot changes.
My strategy? Patch, spray residual, then hang a fake paper nest. So far, had zero returns. Apparent “believe it or not” works.
