Sundew Plant not sticky?

I have a miniature carnivorous bog in a decent sized pot with two small Sun-dew plants, and a Venus' flytrap. Unfortunately I did not realise that too much direct sunlight would hurt the plants as my Sun-dew is not very sticky and is not producing the droplets. When I looked at it under a magnifying glass I could see that there were no droplets of sap and the hairs were burnt at the end. What could I do to remedy this? Thank you for taking your time to read this and I appreciate all of your answers. :)
