Basic rules for use seem to be that if it won't rot down dont flush it and if it kills lots of bugs don't send it to the tank. (e.g. don't clean the toilet and sink with gallons of bleach or the bugs breaking stuff down may stop working)
As you say, they are fairly common here abouts and don't seem to create much of a problem. In fact, most of the time you don't notice any difference.
Animals I like, people I tolerate.
