Bug invasion

For some time now, I've been plagued by a mini insect invasion at home.

[ to be honest, I think they're rather cute... ]

In the past two weeks I've discovered at least five ladybugs in my home. I know, There are worse and more scray insects to find in your home, but still I'd like to know where they are coming from...

This one was on my lamp and is still there somewhere...
