Fall gardens can be a great way to enjoy your outdoor space and enjoy the bounty of nature and delicious homegrown vegetables, fruits and herbs. Unfortunately, pests and bugs that frequent gardens can bring your harvest dreams to a halt. This article will take a look at the 6 bugs that are most likely to ruin your fall garden, and what you can do about them.

1. Aphids

Aphids are one of the biggest threats to a fall garden and can ruin your plants in no time at all. These tiny insects feed on the sap of the plant, which weakens the plant, and can transmit diseases. Common signs of an aphid infestation are wilting and stunted plant growth, as well as misshapen leaves and flowers. Fortunately, aphids can be controlled with a wide range of treatments, like insecticidal soap, horticultural oil, and insect-resistive plants.

How to Treat Aphids

Creating the right environment, and introducing beneficial insects like ladybugs can go a long way in treating and eliminating aphid infestations. It is also possible to remove the infested portions of the plant and dispose of it.


Preventing an aphid infestation can be done by providing plants with enough space and light, as aphids like to live in the shadows. Spraying with neem oil or introducing predatory insects are strategies to further prevent the spread of aphids.

2. Cabbage Worms

Another insect that can ruin your fall garden is cabbage worms, which can cause severe damage to your cabbage, broccoli, cauliflower and kale. Cabbage worms feed on the plant leaves or burrow underneath the surface of the plant and cause yellow spots on the leaves.

How to Treat Cabbage Worms

The best way to treat cabbage worms is to use biological controls like Bacillus thuringiensis, or Bt. Bt is an all-natural bacteria which kills the worms but not the plant or other beneficial insects. You can also introduce beneficial insects like green lacewings or hoverflies, which are natural predators of the cabbage worm.


Prevention is key for cabbage worms and can be done by planting strong varieties that are resistant to their attacks and monitoring the garden for their presence. Covering your plants with floating row cover is also an effective preventative measure.

3. Slugs

Slugs can be one of the most destructive bugs in a fall garden. These pests feed on a variety of plants and can cause major damage to your garden if left unchecked. Slugs leave behind trails of slime and can cause the plant leaves to become spotted, wilted or distorted.

How to Treat Slugs

The most effective way to get rid of slugs is to use baited traps, which can be homemade or store-bought. These traps work by enticing the slugs into a container with a bait like beer or yeast, then trapping them.


Prevention is always the best remedy for slugs, and there are several ways to do so. Placing diatomaceous earth around the base of your plants, handpicking them off your plants and using beneficial nematodes are all good preventive measures.

4. Squash Bugs

Squash bugs are another common garden pest that can wreak havoc on a fall garden. These bugs feed on squash and other related plants, sucking out their juices and leaving behind a wispy, silvery substance. They can also transmit diseases and cause stunted growth in your plants.

How to Treat Squash Bugs

The best way to treat squash bugs is to practice integrated pest management, or IPM. IPM focuses on managing pests and diseases by using cultural, biological and chemical methods to reduce the amount of chemicals used in the garden. Handpicking, growing resistant varieties, and introducing beneficial insects are all good IPM practices.


Preventing a squash bug infestation is much easier than treating it. Planting plants that are resistant to their infestations, keeping plants healthy and monitoring for their presence are all good preventive measures.

5. Spider Mites

Spider mites are a common garden pest that can cause severe damage to a variety of plants. They feed on the sap of the plant, leaving behind a telltale web-like residue and small yellow or white spots. Spider mites can also transmit diseases and cause wilting and stunted growth.

How to Treat Spider Mites

The best way to treat spider mites is with an insecticide that contains Neem oil or pyrethrins. These insecticides can be applied directly to the plant or to the soil around the plant.


Fortunately, spider mites can be easily prevented with a few simple strategies. Keeping your plants healthy and free of stress, introducing beneficial insects, and providing adequate air circulation are all good preventive measures.

6. Cutworms

Cutworms are a pesky bug that can wreak havoc on a fall garden. These caterpillars feed on the stem, root and leaves of plants, leaving behind a telltale cut or notch. They can cause stunted or deformed growth and can quickly spread out of control if not taken care of.
