Understanding Pond Leeches
Pond leeches are found in stagnant freshwater bodies, they are evidences of a healthy ecosystem.
Most species are foragers or predators, feeding on small snails, insect larvae, and organic waste instead of mammal blood.
To understand them, it helps to look past the reasons and check their makeup and behaviour.
Leeches have flattened, muscular bodies with suckers at both ends. They move through the water with an elegant swimming motion or use their suckers to spiral along rocks and plants. They are hermaphrodites, each individual has both male and female organs. They lay eggs in protective cocoons attached to submerged objects. Most pond leeches found in backyard ponds are harmless to humans and are actually great keepers that help keep the water clean by consuming decomposing waste.
Signs You Have Leeches in Your Pond
Leeches are nocturnal and experts at hiding, you may not see them right away even if they are present. They prefer to stay away in dark, damp spots during the day to avoid predators.
On rocks or the pond liner, you may see a small, worm moving by attaching its front sucker, pulling its body forward into a loop, and then re-attaching its rear sucker.
In the water, leeches swim with a graceful motion that looks different from the wriggling of a typical earthworm.
Flip over an underwater rock, a piece of wood, or a floating lily pad, leeches often cling to these surfaces to stay out of the sun.
If you have fish, look for small, worm-like shapes attached to their fins, gills, or underbelly. Even if the leech has finished feeding and detached, you may see small, circular red marks on your fish. Leeches are carried into ponds by ducks or turtles. If you notice local wildlife going to your pond and scratching or biting at their legs/shells, they may be trying to remove them.
How to Remove Leeches from Your Pond (Step-by-Step)
1. Use a metal can or container with a tight lid.
2. Make small holes using a nail.
3. Place a piece of raw meat inside.
4. Add a small rock to keep the trap underwater.
5. Place the trap in a shallow, weedy area of the pond in the evening.
6. Remove the can the next morning. If you have a high population, you may find dozens inside.
7. Dispose the leeches and reset the trap until you stop catching them.
How to Prevent Leeches From Coming Back
Leeches need organic sludge to hide and lay their eggs
Remove fallen leaves and dead plants every few weeks.
Use useful bacteria tablets monthly. These eat the organic waste that leeches live in, evicting them.
Ensure you keep your predator fish active, have a healthy population of Bluegill, or Bass fish. They are natural leech hunters.
If you provide too much fish food, your fish will get lazy and stop hunting the leeches. Keep them slightly hungry so they forage for natural prey.
Which Removal Method is Better: Chemical or Natural?
Natural methods for removing leeches are all about altering the environment to ensure that leeches are unable to survive and hide. The advantage with natural methods is that they are entirely safe for your plants and aquarium animals. Through trapping, you are getting rid of the leeches, while using bacteria eliminates their hiding places.
Chemical methods are considered a quick fix because they can quickly destroy a huge population of leeches in a short period of time. They have a lot of risks associated with them too. These chemicals are not discriminative, they kill beneficial snails and fish, in addition to the leeches.
Natural removal is always the best for a pond owner. This process will create a healthier pond. Chemical removal is always something that has to be approached at a last resort, if the health of the pond is in danger.
Conclusion
The presence of leeches within the pond is more of a sign of the ecosystem that exists in your pond. Leeches will be undesirable in a pond that is clean and lacks dirt. If the aim of cleaning the pond is to get rid of the leeches, the process will ultimately lead to a healthy environment for the fish and plants as well as the insects.
