If you’ve found that your impatiens – those delicate, colorful stars of many gardens – are showing signs of damage, you might be dealing with a common issue. Many potential culprits might be munching on your favorite flora.
Just like a detective story, the clues are there for the keen-eyed gardener to uncover! Are they pests? Disease? Or perhaps environmental factors? Identifying the issue poses a fascinating horticultural challenge, sparking intriguing questions about plant care and protection.
What Is Eating My Impatiens?
The most common pests that eat impatiens are aphids, spider mites, and thrips. Aphids are small, pear-shaped insects that feed on the sap of the plant. Spider mites are tiny, spider-like pests that suck the fluids from the cells of the impatiens, causing it to wilt and discolor. Thrips, on the other hand, are small, elongated insects that also feed on the sap, causing discoloration and possible death of the plant.

|Control||Remove aphids, scale insects, and mealybugs that attract ants; use sticky barriers or diatomaceous earth around plants; use ant baits.|
Effects of Ants on Impatiens:
Ants can cause a significant amount of harm to your impatiens. Although ants do not directly eat the plants, they do farm pests such as aphids and scales that feed on the plant juices. These pests excrete a sweet substance known as honeydew, which ants eat. While feeding, these pests damage the plant, leading to yellowing leaves, stunted growth, and even death of the plant in severe cases.
Managing ants in your garden revolves around control methods and deterrents. Use ant baits for systemic control. These baits contain a slow-acting poison mixed with a food attractant. Ground-dwelling ants carry the bait to the colony, poisoning the entire tribe. Another strategy includes the use of insecticidal soaps or neem oil sprayed directly on infested plants, which will kill aphids and scale insects, reducing ants’ food sources. Tips: Always keep the garden clean, and as a preventive measure, plant herbs that naturally deter ants, such as mint, tansy, or garlic.

Impatiens is often attacked by a small sucking insect known as the aphid. These pests feed on the sap of impatiens, causing leaves to curl, yellow, and drop. Over time they can weaken the plant, stunt growth, and reduce blooming. Aphids also secrete a sticky substance known as honeydew, which can lead to sooty mold development, tarnishing the appearance of the plant and interfering with photosynthesis.
To control aphids, you can knock them off the plant with a strong stream of water from a hose or use an insecticidal soap or neem oil spray, focusing on the undersides of leaves where aphids are often found. You can also introduce beneficial insects like ladybugs, which are natural predators of aphids, into your garden. Regularly monitor your impatiens for aphids and treat them promptly to prevent damage.

Slugs are common pests that affect garden plants, especially impatiens. They feed on the leaves of the plant at night causing holes and a ragged appearance.Slug damage on impatiens can be recognized by irregularly shaped holes in the leaves and a slimy trail left behind. Moreover, slugs can also eat the stems and flowers of impatiens, causing significant damage.
If you see such damage, there are several steps you can take to eliminate slugs. You can handpick them during the night or early in the morning and remove them from your garden. Using traps filled with beer can also lure and drown them, reducing their population. Use of slug deterrents like copper tape around the pots or beds can also help.
Furthermore, you can introduce natural predators like birds or ground beetles into your garden. For extreme cases, commercial slug pellets or pesticides may be applied. However, these should be your last resort as they can harm other beneficial insects. Natural slug control methods are always advisable where possible to minimize environmental impact.

**Snails** are one of the pests that can cause damage to your impatiens. They eat plant materials and their feeding activities result in holes in the leaves and petals of your plants, which can significantly affect their overall health.
**Snails usually feed at night** and they prefer young, tender plant parts. If you notice slime trails on your impatiens, this is a clear indicator of snail activity.
To counter snail damage, it is recommended to use **snail and slug baits**. These baits are based on iron phosphate, a naturally occurring soil mineral, which is safe to use around pets and wildlife. You can spread it around your impatiens to protect them.
Another solution is **handpicking and removing snails manually**, mostly done during their active time at night. Snails can also be controlled with **traps** such as beer traps. Alternatively, you can **use barriers** such as copper tape or diatomaceous earth around your impatiens which irritates and deters snails.
Regularly **cleaning your garden**, removing debris and weeds can also discourage the presence of snails by eliminating their hiding places.

|Control||Implement physical barriers, such as netting, and use organic solutions like neem oil to deter and eliminate caterpillars from damaging impatiens plants.|
Pest Impact: Caterpillars are voracious eaters and can severely damage your impatiens. They primarily consume the leaves, drastically inhibiting the plant’s ability to perform photosynthesis and thereby risking its survival. These pests can quickly defoliate an entire impatiens plant if left unchecked, leading to its eventual death.
Pest Management: To control caterpillar infestations, pick off and dispose of the caterpillars as you see them. You can handpick them off the plants manually, or use a garden hose to knock them off. Also, consider introducing natural predators into your garden to help suppress the caterpillar population, like birds and beneficial insects. Using garden netting can also prevent adult moths or butterflies (which are the parent forms of caterpillars) from laying eggs on the leaves of the impatiens. Another solution is to apply a pesticide specifically formulated to control caterpillars, such as Bacillus thuringiensis (Bt), always following label instructions.

Whiteflies and Impatiens
Whiteflies cause damage to your Impatiens by sucking the sap from the leaves. This not only weakens the plant but also results in curled, yellowed, and dropped leaves. Additionally, whiteflies excrete honeydew, leading to the growth of sooty mold fungus.
Whitefly Control Solutions
For combatting whiteflies, beginning with a strong blast of water from a garden hose can dislodge nymphs and adults. Then, introduce beneficial insects like ladybugs, lacewings, or parasitic wasps into your garden as these are natural predators of whiteflies. Beneficial Insects
Application of insecticidal soap or a neem oil solution can also be effective. Be sure to cover all leaf surfaces, including the undersides. For severe infestations, systemic pesticide treatments may be needed, but these should be a last resort. Insecticides & Neem Oil
Regular monitoring is crucial for stopping infestations before they become serious: inspect new plants before adding them to your garden and regularly check established plants for signs of infestation. Regular Monitoring.

Damage from Spider Mites:
Spider mites can cause significant damage to your impatiens. Although incredibly small, these pests feed by piercing plant cells and sucking out the contents, leading to discoloration and damage. You may notice stippling on leaves, premature leaf drop, or a general decline in plant health.
Solutions for Spider Mite Infestations:
The first step is to confirm the presence of spider mites, which can be done by examining the undersides of leaves for small specks or webbing. To manage an infestation, you can use a strong jet of water to dislodge the mites and wash them off the plants. Other natural predators such as minute pirate bugs or lacewing larvae can be introduced to control spider mite populations.
For more serious infestations, applying a miticide specifically labelled for spider mites can be an effective solution. Remember to always rotate the types of chemicals used to prevent resistance build-up in the mites. Also, maintaining a healthy garden through proper watering, fertilising and pruning can make your plants more resistant to pest attacks. This is a long-term, preventative measure.
It’s important to remember that spider mites thrive in hot and dusty conditions, so maintaining sufficient humidity levels around your impatiens can also deter these pests. Monitor your plants regularly, noting any changes in their condition or growth pattern, as early detection can make controlling pests much easier.

Deer damage is commonly identified by torn or jagged edges on leaves and buds. Impatiens are a deer favorite, these animals often leave a clear path and trample smaller plants in their pursuit of these tasty flowers.
Solutions to Deer Problems
To solve deer problems, you can use deer repellants, fencing, or make your garden unfriendly to them by using plants they dislike. Deer repellants are available commercially, or you can make a homemade one with eggs, water, and dish soap. For a long-term solution, consider installing a deer-proof fence. Alternatively, you can plant something prickly or fragrant that deer won’t eat, such as lavender or rosemary, around your impatiens for protection.

Damages by Squirrels on Impatiens:
Squirrels are often found as culprits when it comes to harming impatiens. Although they do not typically eat the plants, they dig around, disrupting root systems and creating havoc. They are fond of digging soils especially in potted plants or newly seeded areas. When squirrels dig around impatiens to hide their food or just for fun, they may cause the plant to wither and eventually die due to a disturbed root system.
Solutions to Protect Impatiens from Squirrels:
To protect impatiens from squirrels you can use various tactics. One effective way is to dilute hot sauce with water and spray it on and around the plants. Squirrels dislike the spicy smell and taste, which can deter them from digging. Another solution is to cover the soil with stones or create a barrier with a wire mesh. This makes it difficult for squirrels to dig. A helpful tip is to keep bird feeders away from your impatiens as they can inadvertently attract squirrels. Lastly, growing plants that squirrels dislike such as mustard, mint, or marigold nearby can also discourage their visits.

Rabbits and Their Effect on Impatiens
Impatiens, lovely flowering plants, are unfortunately quite attractive to rabbits. Rabbits have a strong preference for soft, succulent plant tissues. Hence, they are frequently found nibbling on the leaves, stems, and shoots of impatiens. This can result in significant damage or even the death of the plants if the rabbit’s appetite is left unchecked.
How to Protect Impatiens from Rabbits
Fortunately, there are several measures you can take to prevent rabbits from gnawing at your impatiens. One of the best methods is to put a fence around your garden. Ensure it is buried at least 6 inches below the ground to prevent rabbits from digging under it. Another solution is to use repellents. Some repellents rely on a bad taste to deter rabbits, while others frighten rabbits off by mimicking predator smells. These are usually applied directly to the plants. You can also consider introducing some predator decoys, like fake owls or snakes, to scare rabbits away. Remember to rotate these decoys often to keep the rabbits on edge. Using a combination of these methods should provide optimum protection for your impatiens.
