Step 2: Design
Step 3: Attach to Pole
Step 4: UPDATE: Paint
Step 5: Put it in Your Garden
I've read around online, and it says a tiny pool of water (as deep as half of a ladybug's height) with some leaves and twigs in or near the house will help attract them. You can also buy chemical attractant, or just buy the ladybugs themselves.
I plan to paint it before I put it out. Ladybugs are attracted to bright colors like green, blue and yellow, and to floral patterns.
I hope this helps someone with a similar pest problem. Thanks for reading!
