I installed a new Bugianator on a 10 ft Free bird hammock this weekend. I followed the instructions on the BIAS website. However, when I got in the hammmock, the bottom of the bugnet and entry hole were about 18 inches below the bottom of the hammock. The top was sitting on the hammock's ridge line. I snugged the entry bungee but did not over-tighten. The hole closed to the size of a dinner plate. What prevents the skeeters from entering this hole. As I mentioned, its about 18 inches below the bottom of the hammock/quilt. Tnx in advance.
