Fill a 2-liter bottle with water and freeze it. Now, hang it above the plant so it can drip onto the base of the plant and cool it. Ice cubes work as well but not as long. These plants are remarkably adept at catching their own food, and also thrive quite well with out insects, living off of sunlight just like any other plant. Don't overdo it.
Pests are uncommon to Darlingtonia and if they do occur, scale is the most commonly seen.
Occasionally aphids will attack the flower stem, or secrete themselves under the newer leaves. Malathion or Diazanon used correctly work well. Darlingtonia flowers in the springtime. The flowers can be self pollinated to produce seed. It also produces stolons that will root and produce new smaller plants.
