At certain times of the year, the multicolored Asian lady beetle,
Harmonia axyridis, comes inside--sometimes in large swarms--to escape
the cold. It's an unwelcome guest because when it feels threatened,
it releases a nontoxic yellow liquid that smells foul and produces
stains. But in one study, researchers found that almost all adult male
and female lady beetles turned away or otherwise tried to avoid the
catnip compound nepetalactone--a substance that also shows promise for
repelling some cockroaches, flies, termites, and mosquitoes.
These findings could lead to a combined "push-pull" control method, which would use repellents to discourage lady beetles from entering buildings and traps to lure and capture the insects so that they can be released elsewhere. This would allow humans to continue to benefit from the beetle's efficient predation of aphids, scales, and other soft-bodied arthropods that damage plants. Eric W.
