The propane-powered 'Mosquito magnet' works well, though it is expensive... But I think it's the single best way to "kick mosquito butt" without spraying chemicals on your skin. Or build a bat house - if you can get some bats to move in, it's an excellent, safe way to make a significant dent in your mosquito population. Of course, if you have buckets or tires or anything else full of water that could be emptied, that would reduce mosquito breeding area and eventually sort of kick their butt. Deet is probably safer than West Nile or EEE, but at high concentrations it does disolve some kinds of plastic, so be sure to watch that. You could try some of the stuff you spray on your clothes (containing permethrin), which is supposed to last 6 weeks or so. I used some for hiking, and it worked pretty well - not perfect, but much better than nothing. It is plant-based and 'natural', but that doesn't necessarily make it healthy - cyanide and hemlock are both made in plants also. As long as you don't spray it on yourself, though, it should be fine on your clothes. Good luck, Andy
