6 Garden Pests That You May Find During The Fall Season

Must read

As the days grow shorter and the air turns crisp, many gardeners revel in the beauty of autumn, tending to their blooming plants with anticipation for the coming season. However, amidst this picturesque landscape lies a hidden realm of creatures ready to wreak havoc on your beloved garden. 

Yes, my fellow green thumbs, the fall season brings a plethora of garden pests, waiting to pounce on your prized flowers and vegetables. But fear not! In this blog post, we will uncover the 6 most notorious pests that emerge during this time of year and equip you with the knowledge to protect your garden from their destructive ways.

Lawn Grubs

During the fall season, one garden pest that you may encounter is the lawn grub. These small, c-shaped pests can wreak havoc on your lawn by feasting on the grass roots, causing significant damage. If you notice brown spots in your garden, it is important to investigate whether lawn grubs are the culprit.

To identify lawn grubs, simply pull on the brown spots in your lawn. If the grass comes out easily with no roots, it may indicate grub infestation. Lift the affected section and check for the presence of grubs. These pests are usually transparent and can be found on the underside of the grass roots.

While a few grubs may not be a cause for concern, having 10 or more in your lawn can lead to serious damage. It is essential to take action to control these pests before they multiply and cause further harm.

The good news is that young grubs are most susceptible to treatment, making fall the ideal time to address the problem. By treating your lawn for grubs in the fall, you can effectively reduce their population and prevent them from causing extensive damage in the springtime.

Boxelder Bugs 

Boxelder bugs, scientifically known as Boisea trivittata, are commonly found in North America. These insects are attracted to boxelder, maple, and ash trees, where they feed on the leaves, seeds, and sap. As the temperature drops, boxelder bugs start searching for warm places to spend the winter, and that’s when they often invade our homes and gardens.

While boxelder bugs are not harmful, their presence in large numbers can be bothersome. To prevent them from becoming a nuisance, it’s essential to take certain measures. One effective method is to vacuum them up using a handheld or vacuum cleaner with a hose attachment. Be sure to properly dispose of the collected bugs to prevent them from returning.

Another simple yet effective way to deal with boxelder bugs is by spraying them with a garden hose. The force of the water will knock them off plants and surfaces, deterring them from lingering in your garden or around your home. For added effectiveness, you can create a homemade insecticide by mixing water and a small amount of laundry soap. Spray this solution directly on the boxelder bugs to eliminate them on contact.

Bagworms are fascinating creatures that undergo a life cycle that begins in the spring. Inside their cozy bags, which hang from branches like peculiar ornaments, the eggs laid by adult female bagworms wait for the right time to hatch. When the warmth of spring arrives, the eggs hatch, and the caterpillars emerge, ready to feed and grow.

These caterpillars have a unique adaptation that sets them apart from other pests. They construct protective bags around themselves using silk and bits of twigs, leaves, and other plant debris. They enlarge their bags as they grow, incorporating more materials into their self-made homes. The bags blend in with the tree branches, making them difficult to spot.

While bagworms primarily feed on evergreen trees, they can also infest deciduous trees and shrubs. They have a particular fondness for conifers, such as spruce, cedar, and juniper, but have been known to target various woody plants. Despite their name, bagworms are not limited to bags alone; they can also create silk tents or webbing within the tree canopy.

Slugs and Snails 

Did you know slugs and snails lay up to 60 percent of their eggs in the fall? If you don’t take measures to eliminate them, they will overwinter and begin feeding in the spring, causing even more damage to your plants. It’s important to be proactive and deal with these pests before they become a real problem.

Slugs and snails are known for their slimy trails, which can be quite a nuisance in your garden. These trails are unsightly and serve as a calling card for other slugs and snails, attracting them to your plants. This can result in a full-blown infestation if not addressed promptly.

One of the main ways that slugs and snails cause damage is by eating the leaves of ornamental plants, seedlings, fruits, and vegetables. They are particularly fond of tender, young plants, which can devastate your garden. Seeing irregular holes or ragged edges on your plants’ leaves is a telltale sign that slugs and snails are present.

Fall Webworms 

Fall webworms are most commonly found on deciduous trees such as oak, maple, walnut, and fruit trees. They prefer to settle at the ends of branches, where they construct their silken webs. They create a haven for themselves inside these webs while they feast on the tree leaves.

Although the unsightly webs can be a nuisance, the damage caused by fall webworms is usually minimal. Mature and healthy trees can withstand their feeding without suffering any long-term effects. However, young or small trees may be more vulnerable and can experience defoliation, weakening them and making them susceptible to other pests or diseases.

If you spot fall webworms in your garden, there are several methods you can employ to control their population. One option is to remove the webs and destroy them physically. This can be done by properly cutting off the affected branches and disposing of them. Another option is introducing natural predators that feed on the caterpillars, such as birds or wasps. Additionally, you can use organic insecticides or botanical sprays that specifically target caterpillars.

Yellow Jackets 

Yellow jackets, often mistaken for bees, are a type of wasp. They are known for their distinctive yellow and black markings, which serve as a warning to potential predators. These highly social insects live in colonies, each containing hundreds to thousands of individuals.

One of the main reasons yellow jackets are considered beneficial is their ability to control caterpillar populations. Caterpillars can cause significant damage to plants and crops, and yellow jackets play a crucial role in keeping their numbers in check. Yellow jackets help maintain ecological balance in your garden by preying on these soft-bodied insects.

In addition to their role as natural pest controllers, yellow jackets are important pollinators. While they are not as efficient as bees or butterflies, they contribute to pollinating various flowers and plants. This makes them an integral part of the ecosystem, supporting plant diversity and the overall health of your garden.

However, it’s important to be cautious around yellow jackets, especially if you or your family members are allergic to their stings. While they are generally not aggressive unless provoked, they can become defensive if they perceive a threat to their nests. This is why watching for yellow jacket nests in your garden or near your home is crucial.

To sum up

The fall season may bring about the beauty of autumn, but it also brings a variety of garden pests that can wreak havoc on your plants. By being aware of the 6 most notorious pests that emerge during this time, you can take the necessary steps to protect your garden from their destructive ways. 

With this knowledge, you can continue to tend to your blooming plants confidently, knowing that you are equipped to keep these pests at bay. So don’t let these hidden creatures discourage you – embrace the fall season and enjoy the beauty of your garden, pest-free.
