Myths that waste a yard
Three stories get a Central Florida yard in trouble: that a bag of beetles will stay, that a wooden hotel will fill, and that every red beetle on a window is a garden friend that should be left in the curtains. UF/IFAS papers already answer all three.
The bag
Commercial Hippodamia are often wild-collected in western mountains, cooled, and shipped. EENY-170 and IN849 warn they may be parasitized and may fly off on a heading that does not help an Orlando bed. Released beetles leave if the yard has no prey or bloom.
The hotel
Beetles overwinter in litter, bark, and wall cracks. A decorative box with holes is not a Sierra talus slope. Spend the wood on a bee hotel only if the design matches a real cavity nester — and that is a different insect.
The curtain
Harmonia axyridis packs houses. Vacuum, seal, and keep the garden hunters. Do not spray a bedroom. Do not dump indoor beetles on a January lawn and expect them to hunt.
Questions
Are lady beetles protected?
They are not a licensed wildlife program on this site. They are garden insects. Do not claim a sanctuary.
