As the smell of pumpkin spice fills the cool, crisp air and fiery hues of fall take over New Jersey, protecting your garden from fall pests is still possible. Aphids, slugs, and spider mites are all on the prowl, looking to turn your garden into their personal buffet before winter hits.

If left unchecked, fall pests in New Jersey can cause serious damage to your plants and soil, and even set the stage for bigger problems next spring. By staying one step ahead of these unwanted visitors and implementing smart strategies, you can prepare your garden for winter.

Aphids

Aphids, often called “plant lice,” are tiny insects which are often found huddled together on the underside of plants and foliage. These little pear-shaped insects can be green, black, yellow, or even pink, depending on their species and the plants they’re feasting on.

Individual aphids are not much of a threat to your garden, but in large numbers they can be quite damaging. During the fall, aphids kick their plant-destroying antics into high gear. As the weather cools, they begin a feeding frenzy, sucking the sap out of your plants like they’ve stumbled upon an all-you-can-eat buffet. This weakens your plants, causes leaves to curl, while they secrete a sticky, sugary fluid known as honeydew. This sticky substance attracts ants and encourages the growth of sooty mold. Left unchecked, these little pests can weaken your garden just as it should be preparing for a restful winter.

The real devastation? Aphids are also adept at spreading plant viruses, so their damage can go beyond surface-level. They’re like tiny viral couriers, causing your garden to struggle come spring. A little vigilance in the fall can go a long way in keeping your garden healthy!

Slugs and Snails

Slugs and snails are nature’s slowest but most persistent garden wreckers. Due to the crippling damage hot temperatures can cause these slimy creatures, they thrive in the perfect balance of damp conditions and mild temperatures that fall brings. While you’re bundled up in a sweater sipping hot cider, slugs and snails are busy turning your garden upside down.

They might be slow movers, but their destruction is hard to miss. If your plant leaves look like they’ve been through a paper shredder, you’ve got slugs or snails on your hands. These little saw-like predators can injure vegetable and fruit harvests. Slugs and snails most vulnerable victims are seedlings while older plants are more tolerant of their depredation. These creatures chew through foliage, leaving behind holes with ragged edges and the unmistakable remnant they leave behind… slime trails. Yes, that shimmering path glistening across your plants or garden stones is their calling-card.

With their ability to hide during the day and snack under the cover of night, slugs and snails can be a real headache in protecting your garden from fall pests. Spotting those telltale signs means you can gear up to send these fall pests in New Jersey packing!

Spider Mites

Spider Mites are stealthy creatures of the garden world. They are extremely tiny, nearly invisible, and capable of causing destruction before you ever realize they’ve invaded. While not insects, these microscopic arachnids (yes, they’re technically part of the spider family!) may be small, but they’re pros at surviving tough conditions, including the chilly fall weather. They thrive in dry conditions and can survive even when the weather turns cold by hiding under leaves, in cracks, or even hitching a ride indoors on your plants. Sneaky, right?

Once these fall pests in New Jersey settle in, they feed on plant juices, sucking the life out of your beloved garden. Their feeding leaves behind a mess. Plants look speckled, discolored, or in poor health with small yellow or brown spots as they sap away the plant’s nutrients. These eight-legged freaks spin webs, which may look like delicate silk. If you spot fine, spider-like webbing on your plants, you’ve got a full-blown spider mite infestation on your hands.

To identify them, grab a magnifying glass and inspect the underside of your leaves for little red, brown, or black dots—those are the culprits. If you’re feeling extra explorative, you can also shake a leaf over a piece of white paper. When you see specks moving, congratulations, you’ve just confirmed the spider mite invasion.

These guys might be small, but they can do extensive damage, so keep an eye out for these garden pests during the fall when they’re looking for cozy spots to settle in for the season!

Caterpillars

Caterpillars might look cute and harmless, inching their way through your garden, but don’t be fooled—they’re the true predators you need to watch out for while protecting your garden from fall pests! Behind that innocent, slow crawl is a voracious appetite for destruction. These guys can chomp through your plants like a kid in a candy store, leaving behind shredded leaves and devastated crops.

The thing about caterpillars is that they aren’t picky when it comes to eating their way through your garden. They’ll chew through leaves, stems, flowers, and produce. And they work fast. One day, your garden looks like a scene from a postcard. The next, it looks like a tornado blew through, leaving nothing but tattered remains. Keep a look out for leaves with ragged holes, missing chunks, or that are completely stripped bare. If so, you can bet you’ve been visited by the caterpillar brigade.

While caterpillars eventually turn into beautiful butterflies and moths, they don’t get any brownie points for their plant-eating habits. So, keep a watchful eye out for these hungry pests before they turn your garden into their personal midnight buffet.

Pest-Proof Your New Jersey Garden

Companion Planting

One of the easiest and most effective ways to control pests is to bring in some co-habituating plants. Certain plants act like natural defenders, keeping unwanted bugs away. Marigolds, for example, can send pests like aphids running for the hills, while herbs like rosemary, mint, and basil can deter everything from slugs to caterpillars. Plant these pest-fighting champs alongside your crops and watch as they become a turn-and-run sign for pesky plant destroyers.

Nature’s Bodyguards

Who said all bugs are bad? In fact, some bugs are your best friends when it comes to protecting your garden from pests in New Jersey. Ladybugs, lacewings, and hoverflies feast on aphids, spider mites, and other troublemakers, while parasitic wasps make life miserable for caterpillars. To keep your garden crawling with these mini superheroes, plant things like dill, fennel, and daisies, which deliver an open invitation to these garden friends.

Building a Garden Fort

Sometimes, the best offense comes down to good defense. To physically block pests from attacking your plants, you can use row covers, netting, or even copper tape for slugs. These barriers act like security gates, keeping fall pests in New Jersey out while allowing your plants to breathe and soak up sunlight. Set these up in early autumn to begin protecting your garden from fall pests—before they move in for winter.

Professional Pest Control

While natural pest control methods are highly effective for managing most garden invaders, sometimes professional help is needed to tackle more severe infestations. When protecting your garden from fall pests in New Jersey, persistent problems like overwhelming aphid colonies, slugs and snails blazing a trail, or caterpillars creating havoc may require the expertise of a professional pest control service. Experts like our Kapture Pest Control team have the knowledge and tools to address large-scale issues safely and efficiently, without harming your plants or the environment.
