Mint is a workhorse in the garden when it comes to giving insects the brush off. To release the strong mint oils in leaves, brush against plants or crush leaves and rub on skin or clothing. Try tucking lightly bruised leaves (still attached to stems) into pockets or bouquets on your porch or patio to confuse and repel mosquitoes. This minty beauty (foreground) is variegated pineapple mint, but you can also use any mint, including spearmint, lemon mint or peppermint. Mints spread aggressively in the garden. Always plant it in containers, even in beds, keeping the edge of pots elevated at least an inch above soil. When mint flowers, the blooms attract beneficial insects, including ones that sting, like wasps. If you don’t want these insects near seating areas, keep plants trimmed so blooms don’t form.
