The most effective way to get rid of frogs is to make your property less attractive to them by removing standing water, reducing insect populations, and eliminating hiding spots. Frogs settle where they find moisture, food, and shelter, so targeting those three things will drive most species away without needing to handle a single frog. For invasive species like cane toads or Cuban treefrogs, more direct removal methods are appropriate and even encouraged.
Remove Standing Water First
Standing water is the single biggest draw for frogs because many species need it to breed. Puddles, uncovered containers, clogged gutters, low spots in your yard that collect rainwater, forgotten pet bowls, and wheelbarrows all qualify. Walk your property after a rain and note every place water pools for more than a day or two, then fix the drainage or remove the container.
If you have a birdbath or decorative pond you want to keep, add a circulating pump so the water stays moving. Stagnant water attracts mosquitoes and other insects, which in turn attract frogs. In ponds, introducing fish that eat tadpoles (like goldfish or mosquitofish) can prevent frog populations from growing. Clean birdbaths every few days. If you find floating egg masses or strings of eggs from invasive species, pour the water out on dry ground.
Cut Off Food and Shelter
Frogs eat insects, so anything that reduces the bug population around your home also reduces the frog population. Outdoor lights attract moths and beetles at night, which makes your yard a buffet for frogs. Switch to yellow or sodium vapor bulbs that draw fewer insects, or turn off unnecessary lights after dark.
Tall grass, leaf piles, woodpiles, and debris give frogs cool, humid hiding spots during the day. Keep your lawn mowed short. Trim low-hanging vegetation to at least six inches off the ground. Clear debris piles, and block access to sheltered areas under decks, AC units, porches, and building edges. The less cover your yard offers, the more exposed and uncomfortable frogs feel, and the sooner they move on.
Plants That Repel Frogs
Certain plants produce compounds that frogs find unpleasant. Peppermint, wormwood, and marigolds are the most commonly recommended. Planting them around garden borders, doorways, or other entry points creates a natural deterrent zone. This won’t eliminate a serious frog problem on its own, but it works well as one layer in a broader approach.
Physical Barriers and Fencing
If frogs keep entering a specific area like a garden bed, patio, or pool enclosure, physical barriers can block them. Fine mesh fencing works, but the details matter. Research on amphibian exclusion fences found that toads could be stopped by barriers as short as 10 to 24 centimeters (roughly 4 to 10 inches) when the fence included a small overhang at the top. Tree frogs, however, can climb, and they weren’t stopped by 40-centimeter (16-inch) barriers unless a horizontal overhang of at least 10 centimeters was added at the top of a 35-centimeter fence.
For practical purposes, use a smooth-surfaced barrier (plastic or metal sheeting rather than chicken wire, which frogs can grip) at least 16 to 20 inches tall with an inward-facing lip at the top. Bury the bottom edge a few inches into the soil so frogs can’t squeeze underneath. Around garden beds or under decks, fine mesh with openings smaller than a centimeter will keep even juvenile frogs out. For buildings, cover roof vent pipes with hardware cloth to prevent tree frogs from entering through plumbing vents.
Keeping Frogs Out of Your Pool
Swimming pools attract frogs because of the water, but frogs that get in often can’t get out and end up drowning in skimmer baskets or floating on the surface. A few simple additions solve both the attraction and the drowning problem.
Cover your pool when it’s not in use. A solid cover or tight netting prevents frogs from entering in the first place, though you’ll want to make sure animals can’t fall through gaps and get trapped underneath. Floating escape ramps (products like the FrogLog or Skamper-Ramp) attach to the pool’s edge and give frogs a way to climb out on their own. You can also place grates or spiral ramps over skimmer baskets so trapped frogs can escape. Even knotted nylon ropes anchored to the pool edge and dangling into the water give climbing animals something to grab.
Motion-activated sprinklers near the pool area can startle frogs away before they reach the water. If you’re building a new pool, incorporating built-in ledges, ramps, or steps along the sides reduces wildlife deaths significantly.
Citric Acid Spray for Direct Control
Citric acid is one of the few sprays proven to kill frogs on contact, and it’s been used extensively in Hawaii to control invasive coqui frogs. The effective concentration is a 16% solution: about 1.3 pounds of dry citric acid powder dissolved in one gallon of water. Many garden supply stores sell premixed 16% citric acid solutions.
Spray it directly onto frogs or onto infested plants where eggs, juveniles, or adults are present. The key limitation is that citric acid only works through direct contact. It leaves no residue that continues to repel or kill frogs after it dries. This makes it a targeted tool rather than a set-and-forget solution, best used for known problem spots during evening hours when frogs are active.
Handling Invasive Species
If you’re dealing with cane toads or Cuban treefrogs, removal isn’t just helpful, it’s ecologically responsible. These invasive species outcompete native frogs, eat native wildlife, and (in the case of cane toads) pose a real danger to pets.
You can capture both species by hand. Wear gloves or put a plastic bag over your hand, since both species secrete irritating substances from their skin. Be quick and decisive when grabbing them. For Cuban treefrogs specifically, short sections of PVC pipe placed vertically in your yard act as traps, since the frogs will climb inside to hide during the day.
The recommended humane method for euthanizing captured invasive frogs involves applying a benzocaine or lidocaine product (toothache gel or sunburn relief spray) generously to the frog’s belly. After 10 to 15 minutes, the frog is anesthetized. Place it in a sealed plastic bag and put it in the freezer overnight. Alternatively, place the bagged frog in the refrigerator for two to three hours first (the cold acts as an anesthetic), then transfer to the freezer overnight. Dispose of frozen frogs with your regular trash. In states like Florida, it’s illegal to catch invasive frogs and release them elsewhere, so relocation is not an option.
Protecting Pets From Toxic Toads
Cane toads are genuinely dangerous to dogs and cats. When a dog mouths or bites a cane toad, the toad’s large poison glands squirt toxin directly into the dog’s mouth. Symptoms appear immediately: heavy drooling (sometimes frothy), pawing at the mouth, retching, head shaking, and vomiting. In severe cases, the toxin can cause weakness, difficulty breathing, seizures, abnormal heart rhythms, and even death.
If your dog bites a cane toad, immediately rinse the mouth with large amounts of water. Aim the water flow forward so it runs out of the mouth rather than down the throat, since inhaling contaminated saliva or water makes things worse. Do not try to make your dog vomit, because neurological symptoms can develop rapidly. Get to a veterinarian as quickly as possible. Time matters with cane toad poisoning, and dogs that receive prompt treatment generally recover.
The best prevention is supervision. Walk your yard with a flashlight before letting dogs out at night in areas where cane toads live, and remove any toads you find. Keeping your yard free of debris, standing water, and insect-attracting lights reduces the chance a cane toad will set up residence in the first place.
