How to Get Rid of a Snake in a Swimming Pool
Yikes! A Snake!
As a pool service technician, I often encounter this problem, and the problem being... I hate snakes!!. Snakes are drawn to the cool water during the summer months, or if you have a heated pool they are drawn to the warm water during the cool season. There is no effect on water chemistry if a snake is in the pool. You don't have to "shock" the pool after a snake has been in it. Really, we just want that snake out of there!
Getting it out
Although I see snakes in pools swimming around, eventually they end up in the skimmer. If the pool pump is off, or not circulating, the snake will free swim until the pump is turned back on and eventually it will be pulled into the skimmer. This is where I usually see the snakes..in the skimmer. Sometimes live, sometimes dead because of the long exposure to chlorine and not being able to get out of the skimmer since the suction is pulling them when the pump is running. Although snakes DO want to get out of the pool, most of the time It's difficult for them to get back out because of the distance of the water surface to the deck or coping.
So, there are a few ways to approach this. If the snake is free-swimming in the pool, usually a net can be used. If a net is not available any type of long stick or even the pool pole, they sometimes will cling to that if you lift the snake up from underneath and can quickly relocate them.
If a pole or stick does not work, and you aren't brave enough to jump in and scare the snake out, you will just need to wait until the snake ends up in the skimmer. Again, remember that the snake at this point probably is frightened and does not want to be in the pool, he just can't get out on his own.
The pool return jets are normally designed and meant to circulate the water, both lower water and top surface. The water on the surface should be flowing one way, and is designed to catch any debris through the skimmer. INCLUDING SNAKES!.. Either way, if the pump is running, eventually the snake will end up in the skimmer. If the skimmer basket is damaged or has has huge cracks and/or holes in it, the snake will end up in the pool pump basket.
You will need to remove the skimmer basket. (I know, the skimmer basket handle is very close to the snake) Use a hook on a pole of some sort to grab the skimmer basket handle and throw that snake somewhere else!
This is the best advice I can give as I have removed lots of snakes from pools. Luckily I have not run into any snake more than 2 to 3 feet. Usually small ones. So if you happen to see an Anaconda, Python or Cobra in your pool....Umm, well.. RUN!! lol.. Hope this has helped
