  • Phil Nixon, Illinois Department of Natural Resources entomologist said Thursday that the recent infestation of multicolored Asian lady beetles is caused by an explosion in the beetles' food stock, aphids, caused by heavy spring rains in our region.
    The rain caused the aphids to multiply far beyond normal and the available food for the lady beetles caused an increase in their ranks as well. The beetles like to congregate in sunny places and the sun side of structures are the only places available locally. In their native China, the beetles congregate on cliffs and boulders, taking in the sun.
    Nixon says they will decrease in number in a few weeks but that they will also take shelter in the cracks of siding during cold weather and reappear in the spring.
    To combat the bugs, use insecticidal soap around plants since it will not harm the plant, only the bug. If there are no plants, then normal insect spray will get the job done. Just vacuum up the critters who get inside homes. Be sure to dump the vacuum bag outdoors.
    The bugs are tough enough to survive a trip through a Hoover, according to Nixon.
    Caulking around doors and windows will reduce the number that get inside.
