I know there are plenty of threads about spraying on clothes. But say you live in a hot/humid environment, wouldn't the heat from the environment help warm and spread the phero products similar to spraying on the skin and letting your body heat up the phero?

Not everybody here lives in a hot a humid environment so people will tell you that in theory it may work or not work as effectively as directly on your skin. The best answer you can get is Test by yourself and report back your conclusions

Sounds like a great answer.. going to start a journal very soon.. just need to find some free time

It might, it might not. Moe is right, you've gotta try and see how it pans out. Do expect diffusion and efficacy to be somewhat affected, since now a layer of clothing is involved.

The only gripe I have with spraying mones on the clothes is that they come off with the clothes. ;)
