Whether you prefer to grow beautiful flowers and trees or a selection of your family’s favorite fruits and veggies, it takes a lot of time and effort to manage a garden. The last thing you want is a horde of these insects literally eating away at all of your hard work.

1. Beetles

Beetles thoroughly enjoy munching on leaves and other plant parts, and they’re not picky eaters—the more types of plants in your garden, the more variety in their buffet.

Japanese beetles, in particular, are one of the most damaging insects to plants. Adult Japanese beetles are pretty easy to spot, as they’re metallic copper and bright green, but the best indicator that they’re living in your garden is skeletonized leaves.

2. Slugs

Slugs alone are enough to destroy an entire garden.

These pests can quickly eat enough of a plant’s leaves and roots to prevent the plant from photosynthesizing, essentially eating the plant faster than it is capable of growing.

3. Caterpillars

The good news is that your garden is unlikely to retain too many caterpillar patrons due to their susceptibility to disease and the wide variety of animals that enjoy them as an appetizer. However, even just a few of these transformative insects can cause extensive damage.

4. Weevils

5. Spider Mites

Plants rely on chlorophyll to convert sunlight into energy, so losing enough of it can weaken, or even kill, a plant.

6. Aphids

They also secrete honeydew, a sweet, sticky substance that attracts ants and grows a black, sooty mold that can prevent sunlight from reaching the chlorophyll in a plant’s leaves.

 

Not all creepy-crawlies are garden pests, and the last thing you want to do is evict the ones that are helping your plants out. If you need help determining whether a bug is hurting or helping your greenery, call a local Best Pick pest control company.
