yes, it will probably bring more, really when you think of breeding season......get it? Most garden centres have humane traps for the little critters. ones that you put cheese in and then they crawl in but cant get out are handy because you can set them free a while off (dont free them to close though, they can be pretty clever!).
i know they can seem very very cute (trust me, i think they are sweet) but if theres more of them they will bring havock to you home!! Chewing up everything, eating you food, pooping....it can be disgusting, unhygenic and plainly....not very nice!
hope this helps a bit!!
