The popular houseplant Chlorophytum comosum does not possess unique properties that specifically lure spiders. The short answer is no; spiders are not drawn to the plant itself. Instead, they are attracted to the environmental conditions and potential food sources that any houseplant can inadvertently provide.
The Origin of the Spider Plant Name
The common name “spider plant” refers to the plant’s distinctive growth habit, not its ability to attract arachnids. This perennial flowering plant produces long, arching stems, called runners, which cascade away from the central rosette of leaves. Small, complete plantlets, often referred to as “spiderettes” or “pups,” develop at the tips of these runners.
These tiny offshoots dangle from the mother plant, resembling spiders hanging on silk threads. The narrow, splayed leaves of the main plant also suggest the legs of a spider, reinforcing the visual connection that led to the common name. The name is purely descriptive, based on visual likeness and botanical structure, with no scientific link to attracting actual spiders.
Environmental Factors That Attract Spiders to Houseplants
Spiders seek environments that offer shelter, warmth, and a steady food supply, all of which a houseplant can provide. The dense foliage of a plant like Chlorophytum comosum offers an undisturbed, sheltered microhabitat where spiders can hide and safely build nests. Plants placed in poorly lit corners or near clutter are especially appealing, as spiders prefer dark, stable areas.
The most significant factor attracting spiders is the presence of other insects, which serve as their primary food source. Spiders are natural predators, and they are drawn to areas with common houseplant pests like fungus gnats, aphids, scale insects, or mealybugs. An infestation of these tiny insects turns the houseplant into a convenient hunting ground and a reliable food source for the spiders.
Moisture levels are another contributing element, as overwatered plants create damp soil conditions that attract spider prey, such as fungus gnats. The warm, slightly humid air created by transpiration can also attract spiders, especially those seeking moisture in a dry indoor environment. Spiders are simply utilizing the small ecosystem a potted plant provides, acting as opportunistic inhabitants.
Managing Pest Presence on Spider Plants
Since spiders often indicate a pre-existing pest problem, managing the environment around the plant is the most effective preventative measure. Regularly inspecting the leaves and soil surface for common pests is important, as addressing these issues promptly removes the spiders’ food source. Look for signs of pests, such as the fine, silky webbing of spider mites or the sticky residue left by mealybugs and aphids.
For immediate, gentle removal, simply brush spiders off the plant or use paper to safely relocate them outside. Proactive maintenance is the best long-term solution. This involves trimming back dense or dead foliage to reduce hiding spots and ensuring the plant has proper drainage. Allowing the top layer of soil to dry out between waterings discourages moisture-loving pests like fungus gnats, making the plant less appealing to hunting spiders.
If a pest infestation is detected, a forceful spray of room-temperature water can dislodge many insects from the leaves, particularly on the undersides. Applying insecticidal soap or a horticultural oil, such as neem oil, effectively controls many common houseplant pests. These treatments target smaller, destructive insects, eliminating the reason for larger, predatory spiders to take up residence.
