When in passing today I happened to mention to my guy Alit that there seemed to be a lot of mozzies around and that I hadn't ever seen so many. Not really expecting much, it being the rainy season now.
He, of course in that Balinese way that says without saying "you know nothing!", casually took me over to where my 1/2 inch exhaust pipe was coming up from the septic tank where hordes, masses, millions of the fecking horrible creatures where issuing from said pipe - clouds of the bastards!
I immediately stuffed the pipe with some steel wool with shouts of "see if you can get around that!".
Point being you might want to check your own pipes and see if there are any unwanted visitors coming out too.
