To attract and keep lacewings in your crops, keep the following recommendations in mind:

- Avoid chemical pesticides, especially contact insecticides that also eliminate beneficial insects.
- Plant flowers that produce nectar and pollen, such as dill, fennel, yarrow or dandelion, which feed the adults.
- Leave areas with natural vegetation or hedges close to the crop, where they can take refuge and reproduce.
- Avoid excessive pruning that eliminates natural shelters.
- Do not apply insecticidal soaps or oils directly on the lacewing larvae.
- If you introduce them commercially, do it at cool times of the day, preferably at dawn or dusk.
