Butterfly Houses & Feeders Section – Our Butterfly Houses are Awesome! Slots in the Butterfly Houses keep birds out while giving butterflies protection from the wind and weather. Place the butterfly house in your garden, and when it gets cool at night the butterflies seek shelter and may use your house. By having a nectar source close by (flowers and/or our butterfly feeder) butterflies are more likely to visit your butterfly house. Each Butterfly House has a door for cleaning and for placing long twigs inside to give butterflies a nice resting spot. Have fun and take delight in watching your beautiful new neighbors enjoy their home.
