How To Get Rid Of Frogs


Summary: Frogs are great insect eaters and are usually welcomed guests around ponds. But, sometimes too many frogs causes us to ask, how to get rid of frogs.

Gus; Yucaipa, CA asks:

We have frogs near a Koi pond that are making a racket. What can we do to get rid of them?

Dear Gus;

Frogs for the most part are beneficial animals eating lots of insects that might otherwise damage plants and vegetables. Unfortunately, frogs come with voices and they love to speak out during all hours of the night, crooning their frog songs. Music to another frog. Unending noise to our ears.


There are lots of reasons the frogs are coming to the pond. The many varieties of insects hatching along the edges of the water make the pond a drive-up smorgasbord for any hungry frog. Of course, the water is a relaxing spa for many types of frogs. So, the decision is how to discourage the frogs from the water attraction. There are many avenues to explore.

Errecting a net screen to ward off bull frogs seems to be a popular idea. The net fence will have to be about two feet high and it will have to be buried into the ground about six inches to keep the frogs from going under. You can also install netting across the top of the pond, securing it around the edges. You can purchase UV resistant three-quarter inch netting from various bird netting suppliers such as Bird-B-Gone or Bird Barrier for about forty cents a square foot. The net allows plenty of air and sunlight through, but keeps out small animals, including frogs.

There are no pesticides labeled for frog control, but there are pesticides that can be applied to reduce the insect populations that the frogs are feeding on. Cypermethrin is a synthethic pyrethroid that can be applied with a hand sprayer. You should treat areas around lights, gutters, leaf litter and other areas likely to attract insects. Knock off the frog's food source and the frogs will have to go elsewhere for their meals.

Some people like to use snake repellents to discourage frogs. Most snake repellents contain some form of naphthalene or paradichlorobenzene, both used in moth balls. The odor is supposed to repel the target pest. Apply it in a band around the area to be protected, but keep it out of gardens and away from areas where it might leach into nearby water. Rain will melt the moth balls and if the melted chemical it makes it into the pond you will have dead fish the next morning, for sure.


Hawaii is fighting an epidemic of a fast-reproducing little frog that was inadvertently brought onto the island. The frog is threatening to endanger the fragile Hawaiian eco-system balance, so authorities have been searching for ways to stop its spread. Two methods that have shown some success and which are being tried under special experimental use permits are a  2-percent-caffeine solution, containing a far higher concentration of caffeine than that of regular coffee. The solution kills the frogs, but does little to surrounding insect populations. In addition to controlling frogs, the solution also does a nice job on garden slugs, the bane of the Hawaiian orchid industry.

Still another potential aid in the frog battle is citric acid, the primary constituent of lemon juice. Preliminary tests used a citric-acid formulation roughly comparable to double-strength lemon juice. The spray isn't quite as potent as caffeine for killing frogs. Hydrated lime, the powder used to reduce the acidity of soil, also kills frogs but cannot legally be used against frogs unless it were to receive federal approval as a pesticide.

A 3-minute spray of hot water (116°F) kills any coquies and greenhouse frogs present. As a bonus the treatment kills geckos, centipedes, and about everything else in the soil except ants. You would have to rent some type of hot water generator to get a consistent spray of that temperature.

The article gives you several ways to control frogs. The main method is to remove their food source which is insects.

I have just uncovered my above ground pool and found frogs & tadpoles have taken over my pool. How do I get rid of them for good.

Get rid of your pool. The pool is providing an environment for frog development. It attracts them. There is no great method of totally stopping frogs.

I live in Indiana and we have a pond in our backyard. We just built our home so the pond is our fall project and has not been completed yet. Our plan is for the pond to be a place where the friends and kids can swim in the summer. Right now its been an oasis for the frogs. The noise is incredibly annoying and when we sit out on our deck we can barley hear our conversation. What do i do to get rid of them while still making it safe for the kids to swim in the pond. Also now because we haven't treated the pond or have an arrator in the pond no one is allowed to swim in it and there are thousands of tadpoles.

You've got a major problem that is not going to go away soon. My suggestion is to call a pond expert to assess the problem. He may go so far as to recommend that the lake be drained.

Sounds to me like most of you people should be more concerned with getting your head check!...Not frogs

I have found that Wasp spray will get ride of your frogs, when sprayed directly on them.

There are sites and many like them all over the web. I do not agree in pest control or doing anything that can be potentially harmful being used on frogs. they are sensitive to chemicals and have thin skin so a lot can hurt them easily. The worlds population of frogs is in decline and this creatures are in danger. You should be so lucky to have a ton of frogs around, a lot of places have entire frog populations being wiped out by disease and pollution. Please just let the frogs be and consider yourself lucky to see them, at the rate we are going they are on the way out sadly. it's tragic and terrible! if you want to learn more there is the site up top and an hour long documentary on the PBS video page called Frogs: The Thin Green Line. It's heartbreaking truly!

Because of the many parasites and bacteria that thrive in frog infested ponds and waters-do not allow any swimming what so ever.Stay out of that frog contaminated water.

Spectracide Wasp and Hornet Killer. Instant disabler, quick death. Can I collect funds from the government for a study? No studying needed. We are overrun with frogs that keep our whole home up all night. We even baked cookies to pass the time. No more. Problem solved. You're welcome, Spectracide. Do a "study" make some money (then cut me a check).

Thanks for this article. I hooked up a hose to our hot water heater. 3 times of using hot water, the frogs are gone from our fountain and small 10'x15'pond.
