Here in the Southeastern US, red ants are a fact of life. Over the last 2 years I've sent several wings off for repairs and the shop said it was really strange, but they saw dozens of micro holes. I wrote it off to our other nemesis and wing threat, the sand spur.
Yesterday my Naish 5M Matador LT held air but went soft. Been using the 6M most of this summer so it's been at least a months since I've used it.
Did the soap test and was grateful the leak was only a foot from wing tip.
Pulled the bladder and all I saw were these micro holes, barely discernible to the naked eye. In the end, 10 we're marked for Tear-Aid repairs.
Then I started seeing the dead fire ants and they were INSIDE the damn bladder. It occurred to me I'd let my wings dry inside the garage a few times and later saw red ants around them, but didn't think anything of it. Until...today.
