Natural control nuisance species

To prevent nuisance from certain animal species, it is important to provide sufficient nesting and hiding places for birds, mammals and parasitic wasps, which feed on these species. For example, great tits are known to be effective natural controllers of the oak processionary caterpillar. Putting up nest boxes encourages the tit population, which then eat unwanted aphids and caterpillars with their young.

Let nature work for you

The approach to enable natural control of unwanted species consists of several steps:

  • Creating a suitable habitat for natural enemies
  • Making the site unattractive to nuisance species
  • Deploying natural fencing with fauna features

Create suitable habitat for natural enemies

Attracting natural enemies begins with creating suitable habitat. Possible measures include:

  • Establishing a healthy green structure. For this purpose, existing greenery can be expanded and planting can be done in new areas. Important is variation in species, height and age of crops, as are plants that bear fruit and provide nectar. A healthy green structure is essential for food, shelter and shade.
  • Water spots where water is always present.
  • Open spaces sand for solitary bees, for example. The females dig tunnels in the sand in which they lay their eggs.
  • Planting flower-rich areas, attracting insects. Insects such as lacewings and parasitic wasps, for example, play a role in controlling oak processionary caterpillars. Predatory mites, predatory flies, parasitic wasps can again help control flies and their larvae.

Making terrain unattractive to nuisance species

Making a building or site unattractive to nuisance species begins by systematically removing food sources and hiding places and strategically constructing natural barriers.

Possible measures include:

  • Planting native herbs. Herbs have a strong scent that keeps flies away, for example, and penetrates deep into the fur of rodents. Rats and mice have a good sense of smell and prefer to avoid this odor.
  • Establishing turf in strategic locations. Rodents do not like to walk on the tussock-like vegetation that is hard and sharp to the touch. This is because the whiskers of rats and mice serve as sensory organs, and when they come into contact with grass pollen and blades of grass, the animal finds it unpleasant.
  • Installing ground oyster and mussel shells at strategic locations around stables. Rodents do not like to walk on this with their sensitive paws

Deploy natural fencing with fauna features

Together with earlier steps, we can create fauna facilities and shelters for “natural enemies. This integrated approach will reduce temporary nuisances of certain species and provide a more balanced local microclimate.

Possible natural measures are:

  • Hanging nest boxes. Birds and their young help reduce unwanted aphids and caterpillars such as the oak processionary caterpillar.
  • On sports fields and golf courses, starlings can ecologically control damage caused by leatherjackets (larvae of crane flies) and grubs (larvae of the leafhopper beetle). This creates fewer bare spots in the grass.
  • Placing nest boxes for raptors. Kestrels and stone and barn owls are reliable mice and rat catchers.
  • Placing bat and mammal boxes. Hedgehogs have a penchant for snails, while a single bat consumes more than 3,000 mosquitoes, moths or beetles per night.
  • Installing insect walls.
