Lady Bugs - Knowledgebase Question

I have read all the letters others have wrote in reference to the Lady Bug situation. I am not sure they are Asian Lady Bugs? Its seems like everyone in the area and surrounding States have the same situation. There are ton's of them everywhere. Mostly outside everywhere, on the buildings in the sun. They do get in the house because of the opening of the doors. They will catch a free ride in on anything that moves. They ares pesty in the house but- We went fishing over at Lake Michegan and they were flying every where and landed on ya all the time. They seemed to bite. My husband says he read they are a special lady bug brought in from another country to control certain pests in crops. He claims he read it some where. My question is-are they the same as our usual ones? Is there anyway to put some in jars and keep them for a good supply for next years garden? Where do they go for the winter usually?

They were brought in to control pests such as those found in orchards and they will eat aphids in your garden, too. As you have seen, these ladybugs converge in preferred locations such as a warm, sunny western wall and then shelter in crevices (attics are a favorite spot)for the winter. In spring they emerge and disperse. If you have some in your yard or general area now, then they will be in the vicinity in the spring. They will come to your aid if ever there is a sufficiently heavy aphid infestation. The secret to attracting the ladybugs is to allow the infestation to build naturally, then at what seems like the last minute they arrive and do their job. In my experience, they must be pretty effective because I have lady bugs in my attic and have not seen an aphid for years. Finally, it is a good idea to caulk every possible gap on your house because they become very pesky when they get in.
