Frogs can actually be of great benefit to your garden, but they can also be somewhat of a nuisance too, which is why some folk enquire about frog deterrent precautions they can take in their gardens.
Seeing the occasional small frog sitting on a lily pad can be quite charming. However, come the mating season and you’ve got fully grown adult male bullfrogs by the score, all calling out to attract females; and that cute little animal on the lily pad suddenly becomes something capable of keeping you awake all night.
Having finished mating, they can produce so much frog-spawn themselves that your pond could look unsightly for weeks. However, having said that, Koi Carp in your pond will love eating the young tadpoles.
Why Frogs like Gardens
So, any of the above reasons might be why frogs are a nuisance, but why do frogs like your garden in the first place. The answer to that is simple; because there is a pond in it. Although you can read reports of frogs being found in back-yard swimming pools, such occurrences are unusual as the frogs don’t like the chemicals in swim water.
Whereas, a garden pond is an ideal habitat for a frog, or indeed an army of frogs. It doesn’t matter whether the pond is naturally occurring, an old established or brand new one, it will attract frogs as they love not only the water in the pond but the damp areas around it too.
Frogs can spend as much time out of a pond as in it, as they really prefer sitting on land where there is plenty of damp shade - near the pond. Which should give you a clue about frog deterrent measures.
Another reason frogs liking gardens is because all those luscious plants you’ve cultivated and grown attract the insects, snails and slugs that frogs love to eat. What about if you have a full blown lake in your garden? Well then surely it is far enough away from your property for the frogs not to bother you.
We’ll start with the most drastic one, which is filling in your pond with dirt or cement. No water means nowhere for the frogs to mate, which is the main reason that they’re attracted to your pond in the first place.
If filling in the pond seems a little too drastic then perhaps making the pond shallower by in-filling it with rocks and earth will help. Frogs prefer ponds at least 12 to 18 inch deep for mating, so if you only want marginal plants in your pond reduce its depth to 6 inch or less.
Another drastic idea would be to remove the plants around the pond that are providing damp shady places for the frogs to stay under. The down side of this idea is that it may well take away the whole look you were trying to create by having the sort of plants that like the damp conditions near pond edges.
Depending on the size of your garden you could always try and develop an area away from your property and main pond that the frogs will find even more attractive, diverting them away from where you don’t want them. You could achieve this by adding a second pond with plenty of damp shade around it made of plants that will deliberately attract the food that frogs like.
Some people talk about erecting frog barriers. Frogs are determined creatures that will walk considerable distances to get to their favorite breeding pond and, as you’ll know, are prolific jumpers. So, if you do opt for a barrier to prevent them getting into your pond - be prepared for it to be a tall one.
