sorry not to reply sooner, had to go out of town for a few....... no, no insect problems here. i have ten acres of property in the sierra nevada foothills, so i have many critters of all kinds here. i dont know how it got in there, as the only way it could have come in is through the front door(my windows are all screened), and made its way all the way across the living room to the tank. it was just your everyday treefrog, ive got them all over outside(i like them, they eat bugs!) but no, definately no bugs in my house! craazzy!
