Check for aphids, spider mites and black spot. Persistent drying or unsuitable water can also stress the plant, so inspect the medium and water source before assigning a cause.
How to care for a Venus fly trap
Venus fly trap needs several hours of direct indoor sun, low-mineral water, and an acidic medium that never dries out. A cooler winter rest is part of its cycle.

Find a bright, steady position
Light and temperature
Give the plant several hours of direct sun from a south- or west-facing window, with bright light as the indoor baseline. Acclimate it before moving into stronger sun.
Higher humidity is useful. Iowa State gives about 21–24°C for summer growth and 13–16°C for winter rest, but these are care ranges rather than hard survival limits.
Check the mix, drainage and pot
Watering, drainage and repotting
Keep the acidic medium from drying out and use rainwater, distilled water or reverse-osmosis water rather than assuming mineral-rich tap water is suitable.
Use a nutrient-poor acidic medium such as sphagnum peat with coarse sand, without ordinary compost or fertilizer, in a container with drainage. No repotting interval is established.
Feed only during active growth
Fertilizer and active growth
Routine fertilizer is generally unnecessary. Iowa State describes optional very dilute fish emulsion in spring and summer, while NCSU advises no fertilizer. Never feed raw meat to the traps.
