Brown Spots on bird of paradise

bird of paradise with brown spots

What's Happening

Spider mite infestation (Tetranychus urticae) causes brown stippling spots on Bird of Paradise leaves. The microscopic arachnids extract chlorophyll via rasping mouthparts, creating thousands of tiny feeding punctures that appear as mobile brown dots and progress to bronzing. Low indoor humidity (<50% RH) accelerates population explosions.

How to Fix It

  1. 1

    1. Inspect leaf undersides with magnifying glass for fine silk webbing, eggs, or moving mites

  2. 2

    2. Isolate plant immediately; remove heavily infested leaves

  3. 3

    3. Shower foliage weekly with tap water blasts to undersides to dislodge pests

  4. 4

    4. Apply neem oil spray (1-2% solution) or insecticidal soap weekly for 3-4 weeks

  5. 5

    5. Ensure full coverage including leaf undersides; treat early morning or evening

How to Prevent It

Maintain 50-70% humidity year-round; quarantine new plants 2 weeks; conduct monthly underside inspections with 10x loupe.
