title says it all. i just noticed that a male had climbed up near the top of the enclosure. i had to remove them from my glass enclosure cause they climbed up the silicone glue in the corners using it as a ladder of sorts. when applying the vaseline to keep them from getting out does one apply a thick layer of vaseline or a thin layer?? i've been using a thin layer and am beginning to have doubts to the efficiency of that thin layer.
