Biological pest control

We use biological pest control

We live in beautiful surroundings down by Bagsværd Lake. This is a local environment we want to help protect. Therefore, we choose to use biological pest control. With biological pest control, our gardeners are not exposed to pesticides. Here, beneficial insects do the work. During the season, we release beneficial insects into the nursery weekly. This way, we continuously monitor the pest population. To keep the population of unwelcome pests in our plants down, we use Borregaard Bioplant APS as a supplier of biological pest control. Borregaard sells to both businesses and private customers. Read more about biological pest control from Borregaard here or buy biological pest control here.

How to control pests in your garden

For treating pest infestations on your outdoor or indoor plants, we recommend using biological pest control. First and foremost, as a customer, you will get the most out of biological pest control if the outbreak is detected in time and combated early. Unwelcome pests are difficult to control if the outbreak is already very large. When you discover a pest outbreak, it is important to initiate treatment, which means you should wash/rinse the plant with water, as well as the plant's surroundings (e.g., greenhouse). Cleaning is important because pests can be in many places. Therefore, you should also continuously monitor your plants, especially on the underside of the leaves. A magnifying glass can be helpful here. Some plants tolerate pruning, where heavily infested areas are removed from the plant. We recommend that you speak to a gardener about this. Once the plant has been cleaned and/or pruned, you can begin your treatment with beneficial insects. Read more about the different beneficial insects here. Our best advice when it comes to biological pest control is to initiate treatment, but also to be patient. Biological pest control is a process, whereas the old method with forbidden pesticides was a shorter treatment process, but unfortunately also bad for the environment.


We recommend that you talk to the gardeners about your specific pest outbreak, and refer to nyttedyr.dk for purchasing pest control.

Did you know you can find ladybug larvae in your garden?

If you're lucky, you might actually have some beneficial insects in your garden yourself. For example, you can find ladybug larvae here, which are good against aphids.

Ladybug larvae, what do they look like?

Here is a ladybug larva. It can vary slightly in size. It is recognized by its spiky-like rear end, legs on the front part, and the two orange-red markings on the side of the back part of the body.

Attract more insects and birds to your garden. 

When you have a rich insect and bird life in your garden, nature's creatures help you keep pest populations down. This can be achieved by using insect-friendly plants, as well as native Danish plants.
