Biological pest control is the use of living organisms to control pests.

Most used biological control insects

Using nematodes to control beetles


Are tiny worm-like organisms that are barely detectable with the naked eye. "Good" nematodes are useful for garden, lawn and plant

Predatory mites against thrips and blood lice

Predatory mites

Arthropods cold-blooded invertebrates with an external skeleton. A number of predatory mites are useful and can be used as biological control

Predatory beetles against aphids

Predatory beetles

The ladybird is the best-known name for this beetle. However, there are many species, all with their own preferences. regarding food

Parasitic wasps against moths

Parasitic wasps

These tiny flies should not be confused with lemonade wasps. They are many times smaller and not dangerous. They are used against moths and lice, among other things

Orius against thrips, among others

Predatory bugs

Orius laevigatus is a small predatory insect (predatory bug) that feeds on thrips. It is an effective biological control agent against thrips and related pests

Netting flies against mealy bugs

Wire flies

Lacewing larvae are small, wingless insects that are the offspring of lacewings. The larvae are voracious predators of aphids and mealybugs

Biodiversity has declined in recent decades. Partly because of this, pests are more likely to develop in large numbers. Biodiversity has declined due to the use of chemical pesticides. These agents are non-selective which means they kill every insect and other organism. Thus, in the past, many beneficial insects also fell prey to these chemical pesticides. Since 2015, the use of these pesticides has been banned and only organic pesticides are allowed.

Biological control agents target only the harmful organisms and, unlike chemical pesticides, do not affect the good organisms. An example would be nematodes. These soil worms are barely perceptible to the naked eye and are not harmful to the environment. As soon as there is no more food, they die out and leave no trace. They feed on larvae of grubs, grubs, leatherjackets and mourning flies, among others. Because of this selective nature, you don't have to worry about other organisms being affected.
