After a huge year for Blue Rhino/Uniflame SkeeterVac line of mosquito traps, the Bait Blocks for all popular Skeetervac models are now in stock and are available to purchase.
You may order them here http://www.mosquitocontroltrap.com/inc/sdetail/2232 

I'm currently trying to get some feedback from the manufacturer on the changes to the 07 lineup. I'll post my finding here as soon as I find out anything.
