lady bugs

Lady bugs are just so annoying this time of year.

A lot of them gets in the house and seeing them flying or crawling in the ceiling are just so disgusting. Although they don't do any harm but i would be happy to get them out because of my girl.

I wish i can do something to get rid of them completely. I did the vacumm but thats it, we still see some in the house. Are there any safe spray to kill them? I search online and found out that burning lemon scented candles might work. Don't know it yet but i have to try this out first.
