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.

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.
