Well, the last time I was around the Matagordo country the mosquitoes were 
about big enough to fly away with small children. And according to rumor did 
fly away with a couple of wash pots. So I do understand you want to keep them 
out of your house. Especially since West Nile Virus has become common. 

But really, HV insulators are overkill unless you are running some serously 
high power. We used to drill two holes an appropriate distance apart in a piece 
of plexiglass (lucite) and replace a window pane, solder a lug to each wire of 
the outside run of ladder line, run #8 screws through the lugs and through the 
plexiglass. A nut on the inside secured that part. Two more lugs on the inside 
run of ladder line and a couple of more nuts finished the feedthrough. 

Plastic would be better since it does not absorb water - and in window pane 
sizes it should be cheaper - but if you must use plywood a few coats of 
Varathane or a similar varnish should keep the wood dry.
