We saw this creature today morning around 11.10am when we were about to go out.
We called bomba at 11.15 a.m and being transferred to the unit in charge after telling the operator "Ada ular" .
He told us to keep watching at the snake to see where it moves to. We kept our eyes on this creature until ~11.40 a.m. It moved its posture for a few times and glided up the ceiling at last to hide there before the rescue crew arrived. Seriously under hot sun and such situation, minutes passed by like hours although it's just ~25 minutes.
The snake immediately hid into the gap of the grill when the crew (4 persons) came in group 'looking' at it. There was once the snake missing in sight. Luckily they told me to get the Ridsect. After spraying into the hole/gap, the snake couldn't stand and moved out!
