How to Get Rid of Worms in Your Pool

You’d think that worms are not a concern at all when it comes to maintaining a swimming pool. Often, it is about checking the levels of chemicals, keeping the debris out and cleaning the sides and ladders into the pool. So what are we talking about?

Strange as it may seem worms in your pool is a common problem. Keep reading and all will be explained and you’ll find out how to get rid of worms in your pool and keep them out for good! Take a look.

I have a series of articles covering how to get rid of or remove certain pests or creatures from pools. Some sound funny but they can be a real problem.

Worms Are Good, But…

No one tells you that these little beasts that usually like to stay in the soil come out of the dug up ground when it gets a little nippy out there. But you have surely noticed them. We always think of worms in the context of landscaping and how useful they are. And that’s true too.

They serve the purpose of tilling and fertilizing the soil and also help plants grow well and look good. As delightful and productive as it is, pools are not a place for worms. In fact, it is kind of disgusting to stay in a pool once you spot one of these.

As the mercury drops in the spring and fall seasons, these organisms get out of the soil and are spotted on pavements and driveways. This is because the cool air brings them out of the ground.

Worms are not great with their sense of direction but if your pool has a deck, that’s their next destination. It is not uncommon for them to fall into the pool and get stuck in there. What you need to do is help them out a bit. And here’s how you do it.

How to Keep Worms Away from Your Pool?

There is no one-stop-shop solution that will take care of the whole problem at once. And if there are too many worms, you have a serious problem at hand. The best thing to do is to keep an eye out during these seasons and clean the pool as and when you spot them.

However, it is not a hopeless cause. We dug out a few tips and tricks to help you out.

Dealing with It Externally

Not a lot of people like pool covers because it is quite inconvenient to have to pull them on or off the pool. But if you are worried about a bunch of worms getting in, this is a pretty effective solution.

It prevents them from entering your water space and blocking your filter. If you feel like this is a frustrating chore, you can reserve this option only for the rainy or cooler months of the year.

There are many types of covers in the market. Keep an eye out for the ones that are easy to operate. This is one of those solutions where you will have to do the time without having committed any crime. But if that’s not sounding great, there are other options.

No Calm After a Storm for You

This is easier than running around with a pool cover. However, it is a little bit of manual work. After a heavy rain, take a walk around your pool and look for the creepy crawlies that are making their way towards your pool. The idea is for you to get to them before they reach the surface of the water.

You could also do a basic cleaning right away to make sure none of them have made it to the filters just yet. This way you can keep them out. And if you’re feeling kind, move them into a grassy patch before they get burnt in the sun.

Rethink the Landscape

This is pretty good life advice too but we will stick to the intricacies of managing worms in a pool for now. A great landscape isn’t one that just looks great but is also highly functional.

When it comes to the area surrounding a swimming pool, as much as you love the view, you must think about utility. While concrete and decorations help eliminate the problem altogether, they don’t belong around a pool.

The look is complete only when you give your pool the cushioning of plants. But those come with soil and it might feel like we are back to square one. What you need to do is keep your flora and fauna at a distance from the water.

That way, these little live fertilizers have to crawl around for a while before they accidentally get dunked. Twenty feet should do the trick but you are not feeling confident, a little extra does not hurt. This means you don’t have to compromise on the look and will succeed in keeping the worms out too.

A Few Inches Go a Long Way

This is a big change if you have discovered the worm problem after building your deck. But if not, you just got really lucky. A lot of the time, the borders of your pool deck seamlessly fade into a patch of grass that joins your yard.

But, if you add a few inches under the deck, the worms will have trouble reaching the water. And it doesn’t have to be a big elevation. Just a little height is all it takes to get rid of them. They are not really up for the challenge.

But sometimes, even worms can do the unthinkable and get on your nerves. Don’t worry about that. It is an exception-to-the-rule situation. A little clean up should fix the problem. If you have a leaf net pool skimmer (which you should), get it out and you will be done in a few minutes unless you own a giant pool.

A Quick Fix to Get Rid of Worms

We understand that a lot of the above solutions are landscaping changes that you might not be able to do. In that case, here’s a quick fix.

If the number of worms or the frequency at which you find them in your pool is beyond what you can tolerate, consider crushing some limestone and lining the border of your pool with it.

You need to get just enough to add it to the soil that meets the concrete of your pool. It increases the pH levels of the soil around the pool and drives the worms away. So they will automatically head to the other side of the pool.

The only problem with this solution is that it gets washed away with rain. And if it gets into the pool, it will mess up your water chemistry and the filter.

That is why it is recommended that you try this closer to the soil and as far away from the pool as possible. You should also check the water for any remnants.

Take the Kill Shot

This is not the best idea but desperate times call for desperate measures. This is one to try sparingly and when absolutely nothing else works. Insecticides. They are a great way to keep bugs and worms out of certain areas.

The problem with this solution is similar to the crushing limestone solution. Filling the landscape around the pool with insecticides, expectantly, kills every insect in that space. It also sends a warning to approaching armies.

The problem is, if it is closer to the water, you might contaminate your pool. It might also kill the insects you need for your plants. That’s why it’s the last resort.

Parting Words

Worms in the pool aren’t hurtful. It’s just a bit gross. And there’s nothing wrong in feeling that way. Just make sure that you find a solution to your problem and not do things that are detrimental to the ecosystem of the entire pool area. You might have to try a combination of some of these solutions. If it works for you, go for it.
