故事的发生是这样的。。。。。1970年代，北卡的林业部门为了控制害虫，从中国引进
了这种七星瓢虫，放养在西部山区。后来虽然这个项目证明意义不大，七星瓢虫仍然成
功的把北卡变成了自己的家。而且，非常amzaing的是，短短的二三十年里，七星瓢虫
就进化出了一种留在中国的亲戚们不具有的习性：季节性的迁徙和休眠。在中国，通常
在树皮缝里，土块下面越冬。但是在北卡，西部山区的七星瓢虫每到冬天，就迁徙到东
部，进入居民区的房子里越冬。
七星瓢虫不咬人，只是暂借一下宝地越冬。一到春天就自动消失了。现在天气转暖，是
它们从藏身的地方出来准备出发了。

“Asian Lady Beetle Damage
The greatest damage caused by the multicolored Asian lady beetle is the
discomfort they give to homeowners. It is not uncommon for tens of thousands
of beetles to congregate in attics, ceilings and wall voids. When the
heating is turned on the beetles tend to move around inside these voids and
exit into the living areas of the home.
In addition to biting, they exude a foul-smelling, yellow defensive chemical
, which will sometimes cause spotting on walls and other surfaces. Most
people are only annoyed by the odor of these chemicals. However, some
individuals experience an allergic reaction to the defensive excretions.
Sinus irritations and mild skin irritations have been reported subsequent to
encounters with the Asian beetle. It is probably not an over-reaction to
wash hands or other skin after contacting the beetles. In at least one study
, the severity of sinus problems subsided with the removal of beetles from
the home.”
“We live in the middle of the National Forest.............we are
unbelievably, insanely infested with them. Every year. Words fail to
describe the infestation, the swarming........the mess of dead ladybugs (
they die quickly of dehydration if they cannot get out), the smell when you
vacuum them up.........
The only thing I've found that does any good at all is to take the screens
out of the windows in the rooms they are worst in and let them out. They
WILL go out if they can. We put the screens back in after they are mostly
gone in a month or so. It's easier to get rid of some flies than it is to
get rid of the ladybugs............. ”
