Butterfly Houses Don't Help Butterflies—They Attract Wasps

Research Shows Butterfly Boxes Are Ineffective

Studies confirm that butterflies rarely use houses for hibernation, shelter, or chrysalis formation. Instead, the slots become prime nesting sites for paper wasps.

If You Keep the House

Install fine screen mesh over the interior slots to exclude all insects. This preserves the decorative piece without creating a wasp hazard—especially important if you're allergic to stings.
