Nighttime Bites: Why Your Houseplants Aren't the Culprit and What Might Be

Nighttime Bites: Why Your Houseplants Aren't the Culprit and What Might Be

Fungus gnats (common "plant flies") do not bite humans. They lack piercing mouthparts.

Likely Culprits

Investigation Steps

  1. Note bite location, time, appearance.
  2. Inspect bed, furniture, pets.
  3. Set glue traps near bed.
  4. Consult dermatologist or PCP for ID.
  5. Pest control professional if infestation suspected.

Plants Are Innocent

Keep your plants; solve the bite mystery separately.
