As there are no walls, do insects or monkeys come in to the treehouse?
The monkeys never come in, but if they do visit the trees outside, they will mind their own business eating, napping, and perhaps they will watch you! Insects are seasonal and, if around, they are most active for a short while around 6:00PM and then they go to bed for the night. The bedrooms and washrooms are totally glassed in and enclosed — so keep the doors closed to them and lights out so that when you go to bed later, any moths will not have been attracted into the bedrooms by lights. We rarely see mosquitoes. We learned that the insects are creatures of the jungle and are harmless. The grasshoppers can be quite a good size. You are well up off the jungle floor. Do not put hands under patio stones, or in holes — common sense, right? Often we sit out watching the sunset at night from the living room in complete comfort. In Canada you sure cannot do that, at least in most Canadian wilderness. Use the outer bug lights if moths, for example, start being attracted to the inner lights.
