Biological remedies against nudibranchs


The Content Of The Article:

Nudibranchs are a great stress test for every gardener. No sooner do the first plants sprout, they are there and can be found everywhere. Slug and other chemical remedies are not a solution as they can kill not only the slugs, but also their natural enemies and cause serious damage in the garden.
No endless fight against nudibranchs
The nudibranch deliberately chooses a garden. Especially in humid summers it becomes a plague and seldom comes alone. A nature-oriented garden exerts a special attraction on the reptiles and lets them come in large numbers. A single snail can produce up to 600 progeny over the course of a year, providing an unstoppable plague in the garden. Here regular use is required and you should check the conditions in the garden.
The right soil care for the prevention of snail infestation
When spring has arrived, he brings the slugs with him. For a prevention, it is already too late at this time, so that the gardener must be active before the hibernation of the garden and must defend against slugs and their indentation. Here are several options, of which the floor care is one of the most important details. You do not see any snails and for this reason you believe that there are none? You may be right, but forget the nudibranch eggs that are already buried in the ground and just wait for spring to come and allow them to hatch in warmer temperatures. Anyone who loosens the ground in autumn and is careful when covering with bark mulch and does not overlook a snail's nest will not have to reckon with an armada of nudibranchs in the spring. The looser and more crumbling the soil is treated, the greater the chance of destroying all the eggs and being successful in prevention. If the gardener discovers a snail's nest in the soil, he can remove it and cover the soil with bark mulch afterwards.
Different ways to eliminate nudibranchs
The most difficult and guaranteed time-consuming, but also most effective method against slugs is the individual treatment. One should get up early, as nudibranchs use the morning hours for their foraging. Only on rainy days they are active all day and can be collected from the plants and from the earth. A morning mopping-up visit to the garden encourages the nudibranch plague and leads to catching, picking and removing the most unwelcome visitors in the yard. The following options have been proven against slugs and made the garden unattractive for the animals:

  • the worm fence from the hardware store
  • the beer trap as an effective classic
  • the individual care by collecting
  • attract animal predators of the snail (hedgehogs, birds, shrews, toads)
  • For nudibranchs unattractive planting with aromatic herbs.
A hedgehog or shrew in the garden is a natural and efficient remedy against the nudibranch population. Since the snail is on the menu of these animals, a hedgehog-friendly and with nesting boxes as a lure for various species of birds designed garden is ideal. Run ducks are only minimally suitable, as they like the snails on the one hand, but also the salad on the other, and thus do not necessarily consider only the pests as a source of food. Here, a barrier fence can help keep the ducks away from the beds. However, this has the consequence that in combination with running ducks and the daily collection of the snails should take place on the plants.
Nudibranchs do not like all plants
The gardener is best informed about the preferences of nudibranchs and ensures a mixed planting of his beds. The primary preferences of the nudibranch include all forms of lettuce, but also some flowering plants and the fresh shoots of shrubs and perennials. Less popular and repulsive to the species are herbs and plants that dislike strong fragrance and essential oils. Between the salad the gardener can for example:
  • dill
  • nasturtium
  • thyme
  • sage
  • peppermint
  • williams
  • or columbine
plant and thus stop the feeding of the nudibranchs. A fragrant aromatic bed is much less visited than a salad bed, where the nudibranch will serve as a specially prepared for them buffet. It is best to combine all measures. If the gardener loosens the soil in the fall and thereby destroys existing nests with snail eggs, the planting wisely and not to the taste of the slug and on top of an animal-friendly garden that invites hedgehogs, birds and other predators of the snail, he is when collecting on Discover only a very small amount of snail in the morning and be successful in combating completely without chemicals.
A humane treatment of the snail plague
As an angry gardener who has been harmed by nudibranchs, one thinks first and foremost of removing the pests from the bed. Not infrequently, snails are carelessly placed on the compost. This is not very efficient, as nudibranchs are cannibals and you attract new snails with this practice. Any treatment with hot water, salt or the killing of the animals is to be foreseen. If the gardener finds dead snails, he should bury them and prevent them from becoming attentive and attracted by the dead nudibranch. The collected or discovered in the beer trap snails are best spent on a meadow, which is located some distance from their own garden. In order not to upset the neighborhood, you should not throw the animals carelessly over the fence and think that they continue to eat at the neighbors and are no longer interested in their own garden.
Conclusion: When a numerous snail plague, many gardeners feel like in the fight against windmills. Even though the amount of nudibranchs is a seemingly unsolvable problem at the beginning of biological removal, consistency and long-term use will quickly lead to success. Who attracts natural predators of the snail and offers them a nice quarters in the garden, makes the work easier and receives effective and helpful support from nature.
Worth knowing about remedies against nudibranchs
  • The daily collection is helpful, but extremely time consuming and annoying, but in any case also helps against egg laying!
  • By the way, old planks offer a very good possibility of collecting: the nudibranches gather underneath.
  • Of course, the snails should then not be exposed again in remote locations!
  • You can use them e.g. Pour with hot water or vinegar and then dispose of.
Many hobby gardeners swear by beer as a tried and tested home remedy: a cup half full of beer in the garden buried to the edge of the container and attracted by the scent of beer, the snails fall in and drown. An unpleasant side effect, however, is that the scent of the liquid could attract more snails from the neighboring gardens.
Of course, then it is not a pleasant task to dispose of these cups, so it would be a good idea not to give these pests even the opportunity to get to the beds:
  • Copper wire is the name of the solution. This can be spanned around the garden, just above the ground.
  • The snails can not crawl underneath, because copper is poisonous to the nudibranchs because it oxidizes on their skin.
  • Of course, copper is completely harmless to vegetables, salads and Co.
Snail grain is also a commonly used snail control product, but carries the risk of being harmful to other animals. Those who want to do without chemistry completely avoid plants that are resistant to snails (summer flowers, perennials and useful plants).
