Common Garden Pests & How to Treat Them

Don’t let your gardening efforts go to waste when pests invade! Learn how to identify and treat the five most common Lowcountry garden pests.

In the world of gardening, every gardener faces challenges when it comes to protecting their precious plants. Among the most notorious adversaries are a group of garden pests that can wreak havoc on our green havens. In this blog post, we’ll delve into the top five offenders that gardeners often encounter: aphids, caterpillars, stink bugs, squash bugs, and snails plus slugs.

These critters are a real problem in Lowcountry gardens, but with the right knowledge, you'll be better equipped to defend your garden and keep it thriving. Read on to learn more!

Pest #1: Aphids

Aphids, those minuscule sap-sucking insects, are notorious for their rapid reproduction and voracious appetite. These pests can infest plants, causing stunted growth, curled leaves, and even transmit diseases.

To combat aphids, try using natural predators like ladybugs or lacewings, or employ homemade insecticidal soaps. Regularly inspecting your plants and promptly removing infested foliage can also prevent the spread of these tiny terrors.

Pest #2: Caterpillars

Caterpillars —the larval stage of butterflies and moths— may seem harmless, but they can devour entire leaves and decimate your beloved plants!

Identifying the specific caterpillar species can help you choose the appropriate control method. Handpicking larger caterpillars or utilizing biological controls such as Bacillus thuringiensis (BT) can effectively manage their population. As added protection, implementing row covers or physical barriers can prevent their entry into your garden.



Pest #3: Stink Bugs

Stink bugs have gained a notorious reputation for their pungent odor and their penchant for attacking a wide range of crops.

These shield-shaped insects pierce plant tissue, causing blemishes and making your harvest pretty darn unappetizing. To deter stink bugs, consider planting trap crops like sunflowers or using pheromone traps to lure them away from your beloved plant babies. Regularly inspecting the undersides of leaves and manually removing them is also super effective in curbing their population.

Pest #4: Squash Bugs

Squash bugs pose a significant threat to pumpkins, squash, and zucchini. These flat, brownish-gray insects suck the sap from plants, leading to wilted foliage and weakened vines.

To control squash bugs, maintain good garden hygiene by removing debris and weeds. Handpicking eggs and nymphs from the underside of leaves is crucial in preventing their growth. Consider using floating row covers during early plant stages to create a physical barrier against these persistent pests!

Pest #5: Snails and Slugs

Snails and slugs are extra frustrating for gardeners due to their stealthy nocturnal habits. These slimy mollusks can leave a trail of destruction, consuming tender plant foliage and leaving behind unsightly holes.

Combatting snails and slugs involves creating barriers with materials like copper tape or diatomaceous earth. Beer traps —consisting of shallow dishes filled with beer— can attract and drown these pests. Additionally, encouraging natural predators like frogs, toads, or birds can help keep their population in check.


It’s true: gardening enthusiasts face an ongoing battle against garden pests —especially in our warm South Carolina climate— but with knowledge and strategic approaches, it's possible to minimize their impact. By understanding the behavior and characteristics of these top five offenders, you can take proactive measures to safeguard your plants. From biological controls to physical barriers, a combination of preventive and control methods can help you maintain a thriving, pest-free garden. Remember, a little vigilance and a touch of patience can go a long way in nurturing a garden that flourishes, even in the face of adversity.
