That's worth a good review, although of course you do not know in the end whether the effect by now was that these (quite expensive) roles designed, or has implemented all the other tips for mice outdoor garden ... ;-)
So although neither of these roles were touched, we have actually now significantly fewer ticks in the garden, but also barely refuges for the mice had and we store our yellow bags now in a barrel until they are picked up.
Something strange I find, however, that I was a year after the purchase directly from the manufacturer Advertising got now, who offers me buy directly in its online store to discount.
