Ladybug infestation

Hello.  We have problems with lady bugs /Asian. Every year there is no end to them climbing all over my balcony .What is the best spray to use on the walls and pavement on the balcony to keep them away from coming inside the apartment. Thank you,  Donald

Unfortunately, there is no “quick fix” or easy answer to annual lady beetle invasions. Vacuuming indoors, pest proofing and properly timed exterior spraying can provide relief but will not prevent entry of every single beetle.  You should try to caulk every crack and crevice around your home, especially around windows and doors.  When they gather outside in the fall spraying with soapy water may be just as effective and safer than pesticides.   This Kentucky University web site has practical information.
