I would never have guessed these were ladybugs. How do I get rid of these monsters?

Why do you want to get rid of them? Just curious...

In the fall, the adults are attracted to light-colored surfaces which is often a house. Sounds like you have a crop of spring hatchlings which will soon turn into adults. But until then, they will be voracious and their favorite things to eat are aphids! So they should be making their way to your plants soon. They are the good guys.

Two years ago, they also devoured my red raspberries. Regular, old ladybugs, yes; Asian, no thank you.

I want to get rid of them because my house, which is light colored, looks gross covered in them. Not to mention the nasty yellow goo that they are spewing all over the place.

just take a hose and spray them off.

Tried that, they stick like glue. I could get a higher pressure spray but I dont want to kill them. I just want them to go away. Did I mention the smell of their yellow goo? Gross!

well, one thing in your favor is that they don't last very long. i can't imagine why they're not out eating bugs. here is an informative link: http://www.ca.uky.edu/entomology/entfacts/ef416.asp

also, they do NOT eat raspberries or any other plant.

If I had photographed my raspberries that year, I would have pics of Asian lady beetles tucked neatly inside 80% of the total crop. Maybe they were using the berries as sleeping bags. They also cause severe damage to grapes grown at wineries and many other fruit crops. See www.ipm.msu.edu/beetleFruit.htm.

did you read the link i provided? they were intentionally released on food crops to curb pest infestation. perhaps you are thinking of another type of beetle?

ok, i stand corrected. i did just find one link saying that they will, when the their main prey of aphids gets lean, eat sugar-laden fruit. http://www.ipm.msu.edu/beetlefaq.htm

I think at one time they WERE the good guys, but like many Asian imports (intentional and accidental) with no natural enemies, they've become pests in their own right. Emerald Ash Borer is another of the imports that has had devastating effects along with the Asian Long-horned beetle.

i think the first link i read must have been talking about the larvae. i really didn't think about what adult beetles would eat when they run out of aphids.
too much of any one thing is never a good idea, i guess........

In answer to marioval's original question, how to get rid of them: Take a knee-high stocking and slide it inside a vacuum hose end. Fold the top of the hose over the end and secure tightly with a rubber band. Vacuum the bugs being careful not to smear them against your home. That smelly "yellow goo" is actually reflex bleeding that they use to ward off predators. When finished, remove the knee-high, tie off the end, and get rid of the larvae or beetles...outdoors with the trash.

National Geographic provides some info to help clear the confusion:

There are thousands of different ones, and a few are omnivores, probably all of the exotics, usually how that goes. So apparently if you have the "wrong" ladybugs, they can damage the plants. Interesting to learn, but sad to know. Hopefully the birds or lizards or something thinks they're all tasty.

Good comment about too much of a good thing.

Sidney, OH(Zone 6a)

Unfortunately, because of their smelly secretions, neither birds nor lizards find ladybugs tasty. It's similar to Monarch butterflies. Because of their milkweed diet, potential predators recognize Monarch (and the copycat Viceroy) coloration, and they avoid these butterflies. Trackinsand: The article you cited points out the sad fact of our native ladybug decline. All of these imports seem to be replacing native species and upsetting our ecological balance. I hope this trend can be reversed.
