Selecting Carnivorous Plants for Fly Control in California: Water Quality and Pet Safety

A homeowner in Ontario, CA (former dairy land, lots of flies) wanted carnivorous plants in planters using reclaimed water, plus indoor plants, and asked about cat safety.

Water Warning

Reclaimed water is toxic to carnivorous plants (high minerals). You must use rain, distilled, or RO water.

Planters & Light

• Planters are great—can't plant in ground without a constructed bog.
• Full sun required (same as tomatoes or roses).

Cat Safety

• Most carnivorous plants are harmless to cats.
• Nepenthes (Asian pitchers) are mildly toxic—cause stomach upset if chewed, but not dangerous.
