Plants That Attract Pests

  • by

In the realm of gardening, some plants serve as a beacon for pests, luring them into our peaceful green spaces. While these plants often have myriad benefits and aesthetic values, understanding their potential to attract undesirable insects and critters is essential. Knowledge is power, and by recognizing which plants that attract pests into gardens, proactive measures can be taken. This insight also offers a balanced perspective for gardeners, enabling them to make informed decisions about their plant choices.


Marigolds, with their vibrant colors ranging from yellow to deep orange, are a staple in many gardens. Beyond their visual appeal, they have traditionally been used to deter certain pests, creating a perception of them as an ally in pest management. However, as with many things in nature, there’s another side to the story. Marigolds, especially when under stress or not adequately cared for, can attract spider mites and snails. These critters are drawn to the plant, sometimes negating the very reason gardeners might have planted them in the first place.

Moreover, the very scent of marigolds, though delightful and refreshing to many, is precisely what makes them irresistible to specific pests. Snails, in particular, find their way to these bright flowers, treating them as a lavish feast. Therefore, while marigolds can serve a purpose in repelling some insects, it’s essential to keep in mind that they could simultaneously beckon others.


Fennel stands tall and proud in any garden, offering a touch of its feathery elegance. With a hint of licorice in its aroma and taste, it’s a favorite in many dishes and brings a unique texture to garden designs. But for all its culinary and aesthetic benefits, fennel has a notable downside: it’s a magnet for aphids. These tiny, sap-sucking insects flock to fennel, sometimes in alarming numbers, seeking to feed on its rich juices.

Yet, there’s a silver lining to this scenario. As aphids gather on fennel plants, they can serve as a reliable food source for beneficial insects, like ladybugs. These helpful predators are always on the lookout for their next meal, and a fennel plant teeming with aphids could be just the buffet they’re searching for. In this way, fennel might be seen not only as an attractant for pests but also as a tool to boost the populations of helpful garden allies.

Roman Chamomile

A plant of beauty and utility, Roman Chamomile graces many gardens with its dainty daisy-like flowers and sweet scent. Used extensively in herbal teas and remedies, its popularity is indisputable. However, this plant has an uninvited fan club in the form of aphids and whiteflies. Drawn to its tender foliage and aromatic properties, these pests can quickly make a home on chamomile, causing considerable damage.

Whiteflies, in particular, are a nuisance, excreting a sticky substance called honeydew which can lead to the growth of sooty mold on the plant. This not only detracts from the chamomile’s visual appeal but can also compromise its health. Regular monitoring for these pests and appropriate interventions, such as introducing predatory insects, can help maintain the health and beauty of chamomile plants.

Bee Balm

Bee Balm, as its name suggests, is highly popular among pollinators. Its radiant flowers, ranging from red to lavender, serve as a beacon for bees, butterflies, and hummingbirds. However, it’s not just these desirable visitors that are attracted to bee balm. The plant is susceptible to powdery mildew and also attracts thrips, tiny insects that can cause significant damage to its leaves.

Thrips are especially problematic because they don’t just feed on the plant; they can also transmit plant viruses. Their presence can lead to discolored, distorted leaves, taking away from the aesthetic appeal of the bee balm. While its beauty and benefits for pollinators are undeniable, it’s essential to consider these challenges when deciding to include bee balm in a garden.


Clover, with its trifoliate leaves and tiny pink or white flowers, is a common sight in meadows and lawns. Often touted for its nitrogen-fixing properties, it enriches the soil and supports a healthier garden environment. Yet, this plant has a downside in its propensity to attract pests like aphids and leafhoppers. These insects are drawn to the sap-rich stems and leaves of the clover, feeding on them and sometimes transmitting diseases in the process.

Leafhoppers, especially, can lead to a condition known as “hopper burn.” This manifests as a reddish discoloration on the leaves, giving them a burnt appearance. While clover has many advantages, including its ability to enrich soil and its visual appeal, it’s essential to be aware of these potential pitfalls and manage them to maintain a healthy garden.

Crimson Thyme

Crimson Thyme is a favorite for many gardeners, gracing rock gardens and borders with its vibrant red blossoms and fragrant scent. This hardy perennial, while low-maintenance in many respects, has a vulnerability that might come as a surprise. It is attractive to pests like spider mites and scale insects. These tiny creatures, almost imperceptible at first glance, can rapidly colonize the plant, sucking its vital juices and causing its leaves to discolor and curl.

Scale insects, with their protective shields, can be especially challenging to manage. They latch onto the plant, feeding voraciously and often releasing a sugary substance known as honeydew. This can promote the growth of sooty mold, further compromising the health and appearance of the Crimson Thyme. Ensuring a balance of beneficial insects and possibly applying organic insecticidal solutions can aid in keeping these pests at bay.


Dill, with its feathery fronds and distinct aroma, holds a cherished place in the culinary world. From pickling to seasoning, it’s an herb with widespread applications. But this flavorful plant has a hidden side. Dill is irresistibly alluring to tomato hornworms and other caterpillars. These green, voracious eaters can decimate a dill plant in short order, munching their way through stems and leaves with alarming speed.

While these caterpillars can be a nuisance, they also serve as a primary food source for some beneficial insects, particularly the braconid wasp. These tiny wasps lay their eggs on the caterpillars, and their larvae then feed on the host, helping control its population. This natural balance is a testament to the intricate web of interactions in gardens, where even pest-infested plants can play a role in promoting biodiversity.

The Bottom Line

Understanding the allure certain plants that attract pests provides gardeners with valuable insights for maintaining healthy and harmonious green spaces. While the presence of pests can be disheartening, it’s worth noting that many of these same plants also attract beneficial insects, setting the stage for a dynamic ecosystem. Proactive monitoring, informed plant choices, and embracing the natural balances can lead to gardens that are not only beautiful but also teeming with life.
