A certain hotel on Soi Arunothai is obviously having difficulties. Now it has no free wifi, stopped some foods and is often quite bereft of customers.

I noticed their swimming pool has been roped off (more like string than rope), with notices up saying the pool is out of order. It has been this way a little while now. The pool has not been drained. The water is beginning to discolour too.

Being alongside where people sit and they serve food and where people go on a weekend to watch football, surely this is a health hazard in the making?

It is so hot. The rainy season is upon us. Mozzies are going to love this pool as the water stagnates. Surely the mozzie population will explode in that area?

Careful not to name said hotel for obvious reasons

Pour a bottle of motor oil into the pool.

This will float on the surface and stop the mosquitoes from breeding.

Thank you for not naming the facility. It is against forum rules and we take that one very seriously.

I might recommend you writing a review on one of the hotel sites like tripadvisor, booking.com, etc.
