The fact is bodies of water are a natural habitat for many animals, including those that can cause serious harm like snakes and spiders. They prefer darker, more vegetated areas, which provide some protection from predators, but your pretty blue pool will sometimes do the job. Snakes are most active April-October, and spiders are seen year-round.
In my years of pool service, I have seen firsthand how dangerous bites from Black Widow and Brown Recluse spiders can be along with rattlesnake bites.
The best way to avoid contact with these creatures is discourage them from using your pool as their own private oasis. Spiders love to build webs around pools because they like damp areas and because pools attract flying insects, which is a favorite meal of spiders. Hanging out near your pool could mean an easy dinner for them. Be extra aware of damp and dark areas like underneath a pool skimmer or cover. We also frequently find them in the nooks and crannies under equipment. Trim any bushes or vegetation around your pool. Spiders hide in vegetation and search for prey. If the vegetation is eliminated, the spiders have no reason to spend time in or around your pool. “Outside shoes” can also be a hazard. Many people leave a pair of shoes outside to slip into. That’s where spiders can hide. If needed, there are also insecticides that can be very effective.
One of the scariest potential problems when taking a dip in the pool is to find a snake. Most snakes you find in or around your pool are relatively harmless, however we have seen an increase in the rattlesnake population this season. Snakes can be difficult to get out of water once they make their way into it, so prevention is the key to such a problem. While there is no foolproof snake repellent, you can make the area unappealing to them. Ensure grass around your pool is kept short. The taller the grass, the more likely snakes will come around. All tall weeds should be removed as well. Next, remove any clutter, such as toys, pool supplies or tools from the ground. Wood, mulch or compost piles should be as far away from the pool as possible. Any potential hiding spot for snakes will increase the chance of them making their way into the pool. Keep in mind, food scraps and bird seed can attract rodents, which in turn can attract snakes. Lastly, keep a pool cover on when you are not using your pool. This is especially important at night when snakes feel more comfortable coming around homes.
Most importantly, if you feel you have been bitten by one of these poisonous creatures, assume the worst and go to the hospital immediately. Stay safe!
