You will find the information in the "Preset" > "Environment" and in Name>"5M Household Insects" (there are also other choices). BTW, found this in the User's Guide, Aug. 2016. You may use "Edit">"Find" to search in the Guide.
Whenever remote is used, a specimen/DNA is required to be inserted in its slot. In this case, you may use a small insect wrapped in paper tape. Please note, use white BN remote. Black remote after sometime may increase the number of insects, etc. You may need to run this for more than two weeks. Please check if the critters are still around to determine duration.
