Why are pollinators in decline?
Pollinators face many stressors. Honey bees and other pollinators species such as bumble bees suffer from exposure to a parasitic mite disease called Varroa Destructor. These are tiny red-brown parasites that feed and live on adult bees, they will reproduce on larvae, causing weakening of bees as well passing on viruses.
The loss of biodiversity and the wide spread use of pesticides are major threats for wild pollinators. Farmers spray crops with a variety of products designed to protect from pests, but it is believed that a number of these are causing a decline bees.
What can we do?
- Ensure to have plenty of nectar & pollen rich plants.
- Avoid using pesticides as this will harm your pollinators. To keep pests away, plant marigolds and tomatoes to repel greenfly.
- Provide a sheltered area using upturned, broken plant pots with opening points for entry.
