Once you start seeing mites crawling on your cultures, it's safe to assume it no longer works. Also, once you stop seeing dead fruit flies on the paper, that's when I change mine. You can't really go by a date or anything else. I bought papers before that were gone from day 1 and ones that lasted over a year.
Gotcha ya this roll was pretty strong smelling when I pulled it out of the bag so its fresh, Ill probably just go by smell and when it stops smelling Ill change it! Thanks
Is this from experience?
Personally I do not worry about it, flies stop producing,the containers go in the freezer. I use a mite spray on the paper towels under the cultures when I think about it.
Now as far as sniffing the mite spray........
Never done it.
Ok so I am new to this mite infestation problem. I noticed it from two sets of cultures that I bought online from two different sources. So I am thinking the mites went from on culture to the next. Have never had mites as a problem before. Can someone let me know, what is this mite paper/spray/powder you are all talking about??? Thanks.
