I have battery power motorised blinds. About a month ago, one of them stopped holding a charge. No problem, just keep it plugged in all the time, I thought. When I opened them yesterday, I noticed a swarm of ants on one of the windows and blind. Where did these buggers come from?
After I cleaned the swarm up, I inspected the blind. I noticed that the ants were still appearing around it. So I take the blind down. I pull the motorised end out of the aluminium tube. There I found, an entire colony of ants, nesting on and inside the motor, and down the metre long tube.
Suffice to say, I think I found the cause of why the battery no longer charged.
