I have not long moved into a new flat, and it is full of ladybirds! If i enlarge the window to agree to it out, more fly in!! They are everywhere. My flat is verbs and we havent put the heating on. Do ladybirds nest? Is it strange that they are here even though winter is approaching? I havent seen a ladybird for years until immediately. Do they eat spiders??
How can i keep hold of animals away...
