Frequently Asked Questions

What are spider mites and how do they infest plants?

Spider mites are tiny, eight-legged arachnids that feed on plant sap, causing damage to leaves, stems, and flowers. They can infest plants through contaminated soil, air, or by hitching a ride on infested plants brought into the home. Spider mites are particularly attracted to indoor plants with dry, warm conditions, making them a common problem for houseplants.

How do I know if my plant has a spider mite infestation?

Common signs of a spider mite infestation include yellowing or bronzing of leaves, fine webbing on the undersides of leaves or stems, and tiny, moving dots on the plant's surface. You may also notice a sweet, sticky substance called honeydew on the plant's leaves or nearby surfaces.

What are the most common plants affected by spider mites?

Spider mites can infest a wide range of plants, but they tend to prefer plants with soft, delicate leaves, such as African violets, begonias, and ferns. They also target plants with high sap content, like succulents and cacti.

How do spider mites reproduce and spread?

Spider mites reproduce rapidly, with females laying up to 20 eggs per day. The eggs hatch into larvae, which molt several times before reaching adulthood. Spider mites can spread through contact with infested plants, contaminated soil, or by being blown by air currents.

Can spider mites transmit diseases to plants?

Spider mites can transmit plant viruses and other diseases as they feed on plant sap. However, this is relatively rare and typically occurs when the mites are infected with the disease themselves.
