Pests in the garden pond

The Content Of The Article:

There are pure pests in the garden pond, but even beneficial insects can become pests if their numbers become too large. Decisive is often the size of the pond.
Water lilies or more, everything is half so bad. Only when they multiply too much do the insects cause trouble.
A well-functioning pond usually manages to maintain its biological balance. In the first years, after the construction of the pond, however, it can be difficult. It takes a few years for this balance to set in. Small ponds are again more vulnerable.
With pest infestation fast action is important. Who has fish and other animals in the pond, may only use natural pesticides. Caterpillars, beetle larvae and the like can be collected. It is also helpful to spray off the plants. The insects are simply washed away and end up as fish food.
Most insects and pests love the water lilies. This is particularly vulnerable. The pests include the water lily aphid, cicadas, caddisflies and moth larvae.
The water lily aphid likes the soft parts of the water lily that are above the water. They suck the juice out of the plants and weaken them. Pond fish and ladybugs are natural enemies. We can fight them in winter. Then the aphid moves to nearby deciduous trees. There she lays off her eggs. The trees can be splashed in winter. This breaks the life cycle of the parasites.
Cicadas also suck the juice from the leaves. These become brown. However, the pests go only to leaves that are high, so do not lie on the water. If you divide the water lilies that all leaves lie on the water or remove too much of the leaves, you eliminate the cicadas.
In caddis fly larvae are the most dangerous. They hatch from hundreds of eggs that were deposited in gelatinous tubes on the leaves. They are super voracious and eat everything bald. Goldfish and pond carp love caddisflies. Otherwise, they are usually only by chemical means to eliminate.
Even with the moths, it is the greedy larvae that cause the most damage. You can pick them up. It is important to remove fallen leaves from the surface of the pond, as the moths of some moths will overwinter. A pond network offers help.
Back swimmer is called a water bug species, which is not really popular with pond owners. Although the beetle is small, it has poisonous mouthparts that can kill even small fish. Since the beetles fly a lot between different ponds, they are not easy to fight. If a row of small fish die, you should attach a small-meshed net over the pond.
Even the scorpion is not a pleasant companion. He too can kill small fish. You can see the scorpion on the breathing opening, a snorkel-like opening of the spiny spine. If you see this breathing hole on the water surface, you can collect the parasite out. Otherwise, only absolute cleanliness in the pond helps.
Chemical pesticides not only affect the pests. Even beneficials and especially the water inhabitants are then destroyed. The best thing to do is to collect the pests and leaves. You do not have to remove all parasites, only those that disturb your natural balance.
Incidentally, herons are also harmful to the garden pond. They plunder the ornamental fish stocks and can pound the pond sheets with their pointed beaks. Once you find out how easy it is to hunt the ornamental fish, they keep coming back. Mostly just helps to attach a sturdy plastic grille over the pond.
