Fungus in Indoor Mulch: Remove It Immediately

Why Mulch Indoors Fails

Mulch and compost harbor fungi, bacteria, odors, and attract insects. Outdoors, natural controls exist; indoors, they cause problems (smell, flies, spongy growth).

Solution

Remove all mulch and use it outdoors. Any lingering pests will die off within a week.
