I wasn't fighting with you, I was jsut saying that ladybugs are harmless. Sorry if I came across rude. And I care about the environment very much, I pick up any trash I see. And as for the pest thing - trust me I'd cry for the squirrel too.
The only reason I said ladybugs are harmless is that, as a whole, they don't wreak havoc on so many animals that they're a problem. I don't care if an animal is a pest or not, they all need to eat right? Besides, squirrels aren't nearly as pesty as aphids, they don't multiply as quickly. All I'm saying is that it's not the aphid's fault that they eat plants, it's just hhelpful that ladybugs keep their numbers down or we'd be overrun with them. Just a final note - ladybugs wouldn't wreak havoc cause they're native species and naturally live in the wild here. Burmese pythons don't natually live in the US, so when people catch them and release them in the Everglades, they eat species that they probably wouldn't find in their native home. They can;t help it, they need food, but if you ever keep an animal as a pet that doesn't naturally live in your area, don't release it. Ever. If you can't stand the commitment of a huge Burmese python and prepare to keep it it's whole life, don't buy the animal. And frankly, I believe we're getting off topic. All the person asked was a simple question of how to keep ladybugs in her house for a few days.
