Maybe a month ago, Anna. Go online and look for one. Check out the B,B,&B website. The netting actually covers more ground, but I put it up on the patio to show you what it looked like, so I made it more of a square to fit that space. Water in the base keeps it firmly on the patio or grass so no slither-kidees can get in! I give it a couple of puffs of Cutter spray and there's no mosquitoes to bother with.
