Contolling Asian Ladybird Beetles

hwp · Mar 31, 2006

Has anybody found anything that will control these pests? /forums/images/graemlins/frown.gif

Control them? They're a nuisance, for sure, but they aren't truly harmful...

In many places, they're being intentionally grown and released to combat other truly harmful pests such as the wooly adelgid which is killing off hemlock forests across North America...

Harmful? Have you had one bite ya! I haven't found or heard of anything to control them.

My wife has found that they can be controlled with a low air pressure device. A vaccuum cleaner!

She goes around several times a day and all the ones she finds take a ride through the tube and end up out in the garage. /forums/images/graemlins/laugh.gif

While they may not be harmful, when you have several hundred invade your home a day, they are pests. And they do bite. Our vacuum cleaner often gets used several times a day to suck them up, but they just keep coming back. /forums/images/graemlins/frown.gif

I haven't been bitten by one, I'll admit...

Our "invasion" occurs in late fall, other than that we don't really have a big, ongoing problem with them. They must be worse in other areas....

I wasn't meaning to downplay your issue, only to point out that you may be swimming against the tide....

I have apparently good results from using the "Home Defense" sold by Ortho. I spray it around the house outside in the fall, and for the third year, have had good results (either that or they are not as prevalent as they were the two-three years before that). I find thousands of dead asian beetles after spraying. And do not have many in the house at all, compared to years back.
I also use it around the nooks and cranny's for spiders and daddy longlegs. Very effective, IMO. Suppose to last for 3 months (I spray more often than that) and kills when the critters walk across the spray residue.
I also spray the wheelbarrow that I use to bring wood into the house, and also spray the pallets of wood in the fall months.

Apparently they are tasty. Our 14 month old daughter always seems to be spitting out Asian Beetle wings....

I have never had any bite, and I have cleaned up and disposed of a lot of live ones....are you sure we are talking about the same thing? Asian beetles are the little orange lady bugs....

There is a difference between the Asian ladybird bettle and the common North American ladybug. The Asian variety seems to have more variation in color and are often more "yellowish" with more spots than the North American vairety. See attached for a photo of the Asian variety. BTW I just ran across an excellent article on ladybird beetles from the University of Kentucky's Entimology Dept. /forums/images/graemlins/smile.gif

You may want to check with your Ag Extension Service or equivalent up there. We have a swarming of these critters every Fall here, and it turns out that huge batches of them are released to control other pests, as has been pointed out here. On the day we moved into our house we experienced one of the swarms. With all the doors in the house open all day for the movers, you can imagine what we had to deal with for weeks after moving in. I can sympathize with your plight.
