Unless you seal the whole element and evacuate the air you will have moisture in the element (it is
condensate) and it has to drain. If you want to keep the creepy thing out use an open cell foam to
plug the ends it will allow the moisture to drain. This what SteppIR uses and it works.

exception of wasps, most of the bugs and spiders that I see are closer to the ground.  I think that
you are more likely to have them inside your PVC furnace exhaust which is not covered at all and
would cause a serious malfunction if blocked.  Even if they were inside your tubing, I think that a
spider would be less harmful to your antenna than an element full of water.
