Natupol Excel Bombus impatiens

Use Natupol Excel for:Pollination of crops with a high amount of flowers per m2, crops grown under artificial light and in warmer climates.

Packaging:One hive with one colony of bumblebees including a queen, 75-100 workers, brood and sugar water

When to use Natupol Excel?

Natupol Excel is especially developed for crops with a high amount of flowers per m2 (35-60 flowers) per week, such as cherry or snack tomatoes, (straw)berries and for crops grown under artificial light or in warmer environments.

How does Natupol Excel work?

After their release, worker bumblebees will start pollinating the crop. They are supported by more workers born in the weeks after their introduction.

The Natupol Excel contains a larger volume of sugar water, adjusted to the needs of the crop. This increases the overall pollination potential and gives the bumblebees more energy to control their own microclimate. The hive also houses a larger colony and thus requires more cooling. Therefore the ventilation openings are modified to improve ventilation. Screens in the ventilation openings prevent insects from entering the hive.

The improved visibility of the hives (Beevision) among the crop is based on the way bumblebees see. Bumblebees now easily find the hive, fewer bumblebees get lost in the greenhouse and pollination improves.

Application Natupol Excel

  • Distribute the Natupol hives evenly along the main path of the greenhouse
  • Place the colonies on a horizontal platform (avoid inclination, otherwise sugar water may leak)
  • During summer; Position the hive about 20-60 cm above the ground on the south-side of a path to obtain maximum shade from the crop. If needed, provide additional shading.
  • During winter; Position the hive near the top of the plants on the north side of the main path. Ensure that the hive is exposed to the first daylight.
  • Wait at least for 15 minutes after positioning the hives before opening the hive entrance, this allows the bumblebee colonies to calm down.

Best working conditions Natupol Excel

Natupol Excel performs best at an ambient temperature of between 10-30°C.


  • Every hive contains food in order to keep the bumblebees in good condition during transport and storage.
  • To guarantee the best pollination results, start using the hive on the day of arrival.
  • Start using the hive no later than one day after arrival.
  • Maintain the bumblebees at a temperature of between 15 – 25°C.
  • Avoid direct sunlight on the hive.

Special points of attention

  • Make sure the hives and the entrances are well visible, so the bumblebees easily find their way home.
  • Place no more than two hives next to or close to each other. To reduce drift of bumblebees, make sure each hive entrance points into a different direction.
  • Please note that direct sunlight on the hive can increase the internal hive temperature with 5-15°C. It is important to provide shade in warm conditions.
  • Make sure ants cannot reach the sugar water of the hive by making a barrier of grease or insect glue. Also avoid contact between plants and the hive, so that ants cannot reach the hive.
  • Avoid colonies to be placed in the direct surrounding of the CO2 supply, or in other locations where CO2 can reach high levels (over 2500 ppm).

Natupol Excel hives are comparable to the previous Class A hives. They are intended for use in greenhouses that have recently planted and need a consistent amount of pollination over the course of the growth cycle.

Description: Colony with high pollination efficiency for hydroponic tomato crops.
Use: For greenhouses that need a longer, more consistent level of pollination that builds over time. For example, crops with long blooming periods such as tomato crops that are at the beginning of the planting cycle (before full bloom) or greenhouses with a constant ongoing operation.
Coverage: 1,000 to 15,000 sq/ft
Longevity: 9 Weeks; Maximum effectiveness occurs between weeks 5-7.
Number of Bees: 80-100 workers
Comparable to: Old Class ‘A’ Hives
Best Use: Best hive for large hydroponic growers with a constant ongoing operation.

Note: This hive takes longer to reach its maximum level, but the hive’s overall performance is more even throughout its lifespan. If you need more pollination faster, we suggest you go with the Excel Startup Hive. If your state requires the Queen Excluder (States West of the Rocky Mountains), you will be sent one of those hives automatically.

We recommend that you schedule a replacement hive to be delivered during the 7th to 8th week. (The larger the square footage – the more frequently you may need to reorder.) This will allow time for the new hive to become acclimated to your greenhouse before the old hive gives out.
