New Update, June 23, 2003
I have gotten an overwhelming number of emails about the Asian ladybug beetles this year. If anyone has digital pictures they would like to send, that would be appreciated.
It was really unusual for me to get reports of the beetle infestations from much colder northern states. Here in Pennsylvania, with moderate winter temperatures, we have not seen a lot here.
I am reading more and more about the biting of the beetles. There are now more explanations about the biting.
Although I have not come across any formal scientific papers about the beetle bites, I have found several generally accepted “givens” about the bites.
Most entomologists are saying the “bites” are either from the mandibles or if their legs. Either way, people who react to insect bites are reacting to the Asian ladybugs, either by “bite” or fluidic reations.
These beetles have powerful jaws, but they also have equally powerful leg parts.
First, they are not malicious “bites”. I have read that the “biting” is a way for them to assess their surroundings. I have also heard that they don’t like being molested.
Second, do not crush them, all ladybugs exude a foul smelling fluid and that liquid does stain.
It may also aggravate allergies.
Third, in large numbers these insects, like any insect whatsoever, have been found to aggravate allergies when they are in large numbers in a house.
Fourth, I no longer recommend chemicals for killing them because 99.99% of people misuse them and put themselves and their children and family in more danger with these chemicals.
Hire a professional exterminator, who knows what they are doing. Or check with your local department of agriculture or natural resources department on how to deal with them chemically.
Many chemicals have strict federal, state and local regulations and bans. They are best suited to help you.
Please feel free to ask any questions you may still have.
I visited your site today and read some of the articles and looked at the pictures of the Asian Ladybugs and it reminded me of how my basement looked for almost 3 years. They were nasty bugs!!! They had a terrible odor, left their dirt everywhere and also bit me quite a few times. I would suck them up in our ShopVac and old sweeper, then take out the bags and burn them. Within hours they were everywhere again. I was embarrassed to have company over for a long time because they literally too over my basement. They made a nest in my drop ceiling between the basement and upstairs. I HATED them and I still do. I haven't noticed their presence as much this year, but I know they are still around, just not as bad. Can you provide any information on the nasty critters? Thanks!!
