Andrew MacBain, of Vancouver, BC, asked for $50,000 for 50% of De-Fence, a line of pointed plastic cones designed to deter pests such as raccoons, pigeons and other intruders from roofs, fences and window sills. The cones come in two-foot strips, six to a box, and are durable, weatherable, paintable and reusable. MacBain also runs Pigeon Patrol, a bird deterrent products and services company with annual sales in the high six to seven figures, and said De-Fence is sold to stores at $19.99 with a retail price of $29.99, giving a markup of 350% to 500%. De-Fence has generated about $30,000 in sales since launch and is carried in 50 to 60 stores, mainly in the commercial sector, with MacBain seeking help expanding into residential and retail markets.

Michael Wekerle went out over concerns about using other people's money and experience, and Manjit Minhas went out because she felt the product was too low tech. Joe Mimran offered the full $50,000 for 50%, citing his ability to help with retailer connections, and Jim Treliving and Michele Romanow joined the offer, bringing additional retail and online retail connections. Andrew MacBain accepted the joint offer from all three Dragons.
