Youre at roughly the same lattitude as I am, and we have pockets of chytrid spread throughout our state, and even further north. As a fly fisherman who ventures into water all over, I have started sterilizing all my gear between locations. Not only to minimize my presence as a vector for chytrid, but for the myriad of other diseases/parasites plaguing our native trout
I would recommend all hobbyists assume that their local amphibian populations host the fungus and act accordingly (cleaning your gear between fishing spots is a great example).www.bd-maps.net/maps said:United States

Mosquitoes as vectors for amphibian chytrid is not a totally far-fetched concern. While I don't think there's any evidence to support it, there's at least tentative evidence for arthropods as alternative hosts (citations below). Not to mention the other chytrid species which parasitize arthropods (including insects).Not that I know of but the bug hatches in the pond 20 yds from my house head strait for the lights downstairs where the frogs are. I wouldn't be able to open my windows in the summer to be completely safe. I have had stray mosquitos lay eggs in my tadpoles containers. Just not the right thing to do for the hobby. It may have always been a possibility but now that I know it's been found around here it's only a matter of time till it gets to my own backyard.

That said, I think feeding wild mosquito larvae is a low-risk activity, at least in terms of introducing wild chytrid to captive amphibians, and provided you don't collect them from water shared by wild amphibians. I feed a lot of mosquito larvae in the summers (collected from jars in my yard) and don't plan to stop because of chytrid in my area.
Hobbyists who collect driftwood, leaves, arthropods, or other wild materials should be mindful of the potential they have to introduce pathogens. However, preventing the spread of pathogens from captive amphibians to the wild is much more important, in my opinion. The risk is higher and the cost greater. That's where I focus my attention.
Good point. We should probably keep in mind that the risk of introducing chytrid (to wild or captive populations) was just as real 15 years ago. Except back then, most hobbyists weren't considering their potential role in an amphibian pandemic. Likewise, there are plenty of other organisms that could be spread inadvertently by hobbyists (ranavirus?). So, it's hard to fault a cautious approach.I'm not worried about what we do know I'm worried about what we don't.
Have you considered a UV sterilizer? Unless your RO filter has a high GPH output, a small (13w) aquarium unit may be worth looking in to.Part of my problem is that frogs sometimes fall into my well. Although I have a water softener, pre filter and ro, it still has me concerned something could get thru while changing filters. Although, for the 5th year in a row, I'm supposed to get city water this year.
