In laboratory tests, 0.1 g of each product was applied to 3x10 cm of exposed area on a volunteer's forearm, while in field trials, 1.0 g was applied to each volunteer's leg (from knee to ankle). In the laboratory, the gel dosage form contained 20% clove oil (Gel B) or 10% clove plus 10% makaen oil mixture (Gel E) were promising plant-based repellents against three mosquito species and gave significantly longer complete protection times of 4-5 hours than all other developing products. Therefore, their efficacy in the field was evaluated. Under field conditions, Gel E showed complete protection for 4 hours and gave 95.7% repellency after 5 hours application, whereas Gel B and 20% deet (di-methyl benzamide) provided only 86.8 and 82.7% repellency after treatment, respectively against Ae. aegypti, daytime-biting mosquitos. For nighttime-biting, the 3 repellents under development yielded equally excellent (average 97.1%) repellency for 5 hours against the predominant Cx. quinquefasciatus and Mansonia uniformis, but they gave 89.0% repellency against Cx. tritaeniorhynchus and Cx. gelidus.
How did the American Indians deal with mosquitos?
I've heard that CO2 emmission (exhaled breath) attracts them. Is this true or BS?

They "love" me.That is one way they are attracted to you, along with heat. Not only from breath, but CO2 and heat given off by the skin. The mosquito traps and killers like the Coleman Mosquito Deleto use propane to create this attraction to trap and kill them.
Several other things in the skin can attract them (lactic acid for one), and nailing down which one(s) you are giving off can be much more difficult, if not futile, than than just applying a repellent: http://www.ars.usda.gov/is/AR/archive/feb00/mosq0200.htm
