Ahhh - life in Costa Rica!
Do you have bats hanging around your place "doing their thing" (going caca•pooping•shitting•feces) down your wall which is hard to get rid of???
BB ("Buff Boy") - one of the workers where I used to live, rigged up this idea concept which REALLY WORKED with a BIG problem I was having with LOTS of bats pooping•shitting•feces•caca on the walls as their caca is SOOO HARD to get off the walls (and when you do it will chip at your paint)
• Take 2 CD's
• String them next to each other with the shiny side forward & wrap around 2 nails & vwala - they go AWAY!!!
(I don't get why - but it works!!)
Because the cd's could keep moving - especially in wind - you might want to put another nail in the middle or drill a hole in each cd so you could tie that string through it.
Here are some links to clean it up:
