Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

I've been advised to use ethyl alcohol. Many pharmacies sell it. Others may have better suggestions, so I'll defer to our real bug men if they chime in.

Knik,
Welcome to the forum!
Martinf is right, experts recommend ethyl alcohol and you can get it at drug stores and retailers like Wal-Mart. Hardware stores sell it too, but in cans and there's usually a coloring agent in it, so beware of that source.
Recommended strength is 70% to 90% (the latter being a little harder to find). The best storage is 1 dram glass vials with the plastic stopper caps. Screw caps tend to have a problem with evaporation, so stay away from them if you can. Be sure to label them. The best is a strip of white card stock using a #2 pencil (ink bleeds into the preservative). If you aren't sure what it is at the time, that's OK, just put the date and location. You think you'll remember, but as your collection grows and if you fish a lot of different spots with similar critters, you will get them mixed up. Been there, done that.:) Once they've been positively identified, you can throw away the label and affix a permanent one to the outside if you want.
Personally, the 70% seems to work just fine for long term storage provided you replace it within a few days after the specimens have released their water into the suspension. This is really important when you have a lot of specimens (or a large specimen) in the vial.
Final tip - Make sure that there is no air trapped under the cap. If the vials are moved around a lot, an air bubble can be more damaging than if you had a little pebble in with them.
Tight lines!
