Why do I have frogs in my pool?
You have frogs because your pool looks like a breeding pond and feeds them at night. Frogs are drawn to standing water to lay eggs, and a pool is the largest, most reliable body of water in most yards. Add the insects that gather around a lit pool after dark, and you have both of the things a frog wants in one place: somewhere to breed and something to eat.
The bugs are the bigger draw. Pool lights and the flat, reflective water surface pull in flying insects at night, and frogs follow the insects. If your pool has any algae or organic film, it is also feeding water bugs like water boatmen, which stocks the pantry even more. A pool that has slipped a little green is far more likely to draw frogs than one with clear, balanced water.
Frogs are also strong nighttime travelers that arrive from nearby ponds, ditches, drainage areas, and damp landscaping. That is why an outbreak often shows up overnight, especially after warm rain when frogs are active and looking for new water. The frogs did not hatch in your pool; they hopped or flew in following the light and the food, which is exactly why removing those two things is what solves it.
How do you get a frog out of a pool?
Get a frog out by scooping it up with a skimmer net or leaf rake and setting it in the grass, or by giving it a ramp it can climb out on. A frog cannot grip the smooth vertical wall of a pool, so once it drops in it swims the perimeter looking for an exit, and if it never finds one it swims until it exhausts and drowns. A deep-bag leaf rake reaches a tired frog in the middle of the pool without you getting in.
For an unattended pool, the reliable answer is a floating escape ramp such as a FrogLog, a small foam pad with a fabric ramp that sits at the waterline and gives frogs, mice, and other critters a route to climb out on their own. A partly submerged pool noodle wedged against the wall, or a piece of rope or netting draped over the edge into the water, does the same job for free. Anything that bridges the water to the deck turns a death trap into a place a frog can simply leave.
Check the skimmer basket every day during an outbreak. Frogs that tire out get pulled toward the skimmer and end up trapped or dead in the basket, where a decomposing frog fouls the water and clogs the flow. Clearing the basket daily removes the ones that did not make it and keeps a dead frog from turning into a water-quality problem on top of a pest problem.
Does chlorine kill frogs in a pool?
No, normal pool chlorine does not kill frogs, and it is a slow, cruel, and unreliable way to try. At a standard free chlorine level of 1 to 3 ppm, chlorinated water irritates a frog's skin, since frogs absorb water and chemicals directly through it, but it does not kill an adult frog on contact. What actually kills the frogs in a pool is drowning from exhaustion, not the chemistry, so relying on chlorine just leaves you with dead frogs to fish out.
Do not dump extra shock into the pool to deal with frogs. Overdosing chlorine will not clear them any faster, it wastes chemicals, it can bleach a liner and corrode fittings, and it forces you to wait before anyone can swim. If the water needs shocking for algae, do it for the algae's sake and let clearing the food source, not the chemical, be what moves the frogs along.
Frog eggs and tadpoles are even more stubborn. Chlorine kills them only slowly, and in a pool with low or neglected chlorine they can survive and even develop for a while. Netting the eggs and tadpoles out is far faster and more certain than waiting for the water to do it, which is why the real strategy for frogs, at every life stage, is physical removal plus taking away the reasons they came.
How do you keep frogs out of the pool?
Keep frogs out by removing the two things that draw them: the nighttime bugs and easy access to the water. Start with the lights. Turn off the pool light at night during an outbreak and dim or redirect nearby yard and patio lighting, because the insects gather at the light and the frogs follow the insects. A darker pool at night is dramatically less attractive to both.
Cover the water when the pool is not in use. A solar cover or a [safety cover](/reviews/best-pool-cover) physically blocks frogs from the surface, stops them laying eggs, and keeps bugs off the water too, so it deals with the cause and the symptom at once. Covering the pool overnight, when frogs are most active, breaks the cycle faster than anything else you can do without draining or fencing.
Then take away the habitat around the pool. Trim back tall grass, dense shrubs, and damp ground cover near the deck, and remove standing water in buckets, toys, plant saucers, and low spots, since those are the shady, moist hiding and breeding spots frogs want by day. Keep the pool itself clean and balanced so it never grows the algae and bugs that feed them; the pool maintenance schedule and ideal chemistry levels cover the routine that keeps the water uninviting to pests.
What do frogs hate, and do home remedies work?
Frogs avoid things that irritate their sensitive skin and feet, such as salt, vinegar, coffee grounds, and citric acid, but these work only as a barrier around the pool, never in the water. Sprayed on the deck, coping, and surrounding surfaces, a vinegar or citric-acid solution can make frogs uncomfortable enough to hop elsewhere, and spreading used coffee grounds along the edges does the same. Reapply after rain, because these wash away fast.
Do not put salt, vinegar, or any home remedy into the pool water. Salt will throw off the chemistry of a standard chlorine pool (and even a saltwater pool runs a specific, controlled level, not a frog-repelling dose), and vinegar drives pH down unpredictably. These tricks belong on the deck as a deterrent, not in the water as a treatment, and they are marginal even there.
Be honest about the limits of repellents. The reliable deterrents are darkness, a cover, clean water, and cut-back landscaping, not a scent or a spray. Snake presence, plastic-owl decoys, and store-bought frog sprays all get recommended online and mostly disappoint. If you fix the light and the access and keep the water clean, you will not need a repellent; if you skip those, no repellent will hold the frogs off for long.
How do you get rid of frog eggs and tadpoles?
Net frog eggs and tadpoles out of the pool as soon as you spot them, because removal is faster and surer than waiting for chlorine. Frog eggs show up as clusters or long strings of jelly-like dots floating at the surface or clinging to walls, steps, and the skimmer. Scoop them with a fine-mesh net or a flat skimmer net in one careful pass so they do not break apart and scatter.
Tadpoles are harder because they swim and hide. Run the filter and use a fine net or vacuum to collect them, working the shallow end and the steps where they gather, and empty the skimmer and pump baskets often since the pull draws them in. A pool that stays chlorinated slows their development, but do not count on chemistry alone to finish the job; physical removal is what actually clears them.
The better fix is to stop the eggs from being laid at all. Cover the pool overnight during frog season so females cannot reach the water to spawn, and keep the lights off and the water clean so the adults never gather in the first place. No adults on the water at night means no eggs in the morning, which spares you the whole tadpole cleanup a week later.
Frequently asked questions
What do frogs hate the most?
Frogs hate anything that irritates their skin and feet, so a vinegar or citric-acid solution, and used coffee grounds, sprayed or spread on the deck and coping around the pool will push them to hop elsewhere. Keep these on the surrounding surfaces, never in the water, since salt and vinegar wreck pool chemistry. What frogs truly avoid, though, is a dark, covered, bug-free pool, so darkness and a clean water surface deter them far better than any smell.
What should I do if a frog is in my pool?
Scoop it out with a skimmer net or leaf rake and set it in the grass, or give it a way to climb out on its own. A frog cannot grip a smooth pool wall, so it swims the edge until it drowns from exhaustion. A floating escape ramp like a FrogLog, a partly submerged pool noodle, or a rope draped into the water lets a trapped frog leave without your help. Also check the skimmer basket daily, since tired frogs get pulled in there.
Does chlorine pool water kill frogs?
Not quickly, and it is not a good way to deal with them. Normal pool chlorine at 1 to 3 ppm irritates a frog's skin but does not kill an adult on contact; what actually kills frogs in a pool is drowning once they cannot climb out. Chlorine kills eggs and tadpoles only slowly, and they can survive in low-chlorine water. Do not overdose shock to try to clear frogs, since it will not work faster and can damage the pool. Net them out instead.
What smell keeps frogs away?
Vinegar, citric acid, and strong coffee are the smells most often used, along with the scent of used coffee grounds spread around the pool edge. Sprayed on the deck and surrounding surfaces they can make frogs uncomfortable enough to move on, but the effect is modest and washes off in rain, so reapply often. Never add these to the pool water. The most dependable deterrent is not a smell at all, it is turning off the lights, covering the water, and keeping the pool clean.
Are frogs in a pool dangerous?
Frogs are not dangerous to swim near, but they carry a few real downsides. They can carry salmonella, so wash your hands after handling one and do not touch your face. A frog that drowns and decomposes fouls the water and can clog the skimmer, and frogs in the yard attract snakes that hunt them. The bigger nuisance is usually the eggs and tadpoles they leave behind, which is why keeping frogs out of the water in the first place matters more than any single frog.
