Ironraven,

As for getting bit more after putting on bug spray, I can think of several possible reasons:

1. Do you have a certian set of "outdoors" clothes that you usually wear in conjunction with bugspray? Mosquitoes are attracted to dark colors.

2. Are you doing more strenous activities when coated in bugspray? Mosquitoes are attracted to darbon dioxide and water vapor, two things we put off in abundence, especially when working.

3. Perhaps the solvents that carry the bug spray allow your own chemical attractants to vaporize off your body easier producing an extra-heavy signal to the mosquitoes.

Hmmm, time to get some grad students involved. :-)
