Ordinarily lady beetles are not a nuisance; they feed on ornamental pests like aphids and whiteflies and are considered by some to be good luck.
In the winter however they search out nesting sites, including our homes that protect them from cold weather. Lady beetles are especially attracted to buildings with sunny, western exposures and can crawl into a structure through the smallest of cracks.
Along with using caulking or foam sealants to block their access, maintaining the yard, roof and gutters free of leaf clutter and other debris will minimize a lady beetle invasion.
