In the event of a pest in houseplants or hobby greenhouse, it is best to use Insect Heroes preventively or as soon as you notice the first pest insects. An advanced infestation is always more difficult to treat than a mild infestation. Treating a serious infection is certainly possible, but several repeat treatments will often be necessary. In the case of a pest outside in the garden, the treatment period depends on the temperature. See the relevant pest page for more information about the optimal application period.

For maximum effectiveness, we recommend turning off the Insect Heroes immediately. If you still want to store the product, read the storage instructions in the instructions for use.

Repeat treatment will often be necessary. This applies to both natural pesticides and other (chemical) pesticides. Products often only tackle a selective stage of the pest. If you have a light infestation, the Insect Heroes will easily be able to control the pest. But if you have a significant infestation, one or more repeat treatments may be necessary to break the life cycle of a pest.

A combined application with Insect Heroes and chemical pesticides is not recommended. Always wait at least 3 weeks before releasing Insect Heroes after treating the plants with chemicals. Look after! 'natural' anti-insect sprays and oils are also harmful to Insect Heroes.


This is specific per product and pest. Read more about the effectiveness of our products on the relevant product page. In general, a reduction in pest insects can be expected after 1 to 2 weeks.

Read more information about the shelf life on the relevant product page.

Increase the dose of Insect Heroes. Cut off severely affected parts of the plant while you wait for your order.

A few hours after release, view the Insect Heroes with the handy Loupe . After 1-2 weeks, depending on the pest and product, you should expect a reduction in the infestation.


All insects and mites that we sell are harmless to people, plants or pets when used correctly. After removing the pest, they will disappear from your plants automatically due to lack of food.

Most of our products are so small that they will hardly bother you! After removing the pest, the Insect Heroes will automatically disappear from the houseplants due to a lack of food.
