Plants add to the beauty and fragrance of a garden with much more than flowers. However, they are favorite targets by various pests that feed on their leaves, stems, or petals. If unchecked, they cause severe damage that may result in retarded growth or plant death. Thus, it becomes very important to know about the common flower-eating insects and how to deal with them for a good flourishing garden. Here are 8 common insects that eat flowers and how you can stop them.
1. Aphids
Aphids are small, pear-shaped insects that are available in green, black, or red colors. They usually infest flower buds and leaves by sucking sap from the plant, causing deformed growth and yellowed leaves.
Preventing Them:
Introduce natural predators, such as ladybugs and lacewings.
Dislodge aphids from plants with a strong jet of water.
Use insecticidal soaps or neem oil for very bad infestations.
2. Thrips
These are tiny blades of grass from any of the meteorological insects, which penetrate even the tiniest flower petal into the green leaves to feast on their insides. This results in discolorations, scars, and distorted flower growth.
How to Stop Them:
Use sticky traps for monitoring and catching the adult thrips.
Spraying them with neem oil or insecticidal soap.
Weeds and debris should be kept under check to reduce their breeding grounds.
3. Japanese Beetles
Japanese beetles are shining green metallic with coppery brown wings. These beetles enjoy flowers and chew on their petals leaving skeletonized leaves and blossoms behind.
Stop Them:
Handpick beetles and throw them in soap water.
Toss up floating row covers around plants during the peak beetle season.
Disperse beneficial nematodes that reduce larvae populating the soil.
4. Caterpillars
The larvae of moths and butterflies-aged plants are often stripped bare of all their leaves, or buds may cause serious damage even before they enter pupation.
How to Stop Them:
Handpicking them one at a time from the plants.
Bacillus thuringiensis (Bt), a natural bacterial insecticide that baby-sits caterpillars, will be put to use.
Encourage birds as any other natural predator in the garden.
5. Spider Mites
Spider mites are some of the smallest arachnids. Their feeding on plant juices may cause speckled or bronzed leaves and stems, and fine webbing is left behind on flowers and foliage.
How to Stop Them:
Increase humidity around plants to ward off mites.
Spraying with soap or neem oil mixed with water kills the spider mite.
Introduce predatory mites to keep the balance.
6. Slug and Snail
Although they are not insects, slugs and snails have a habit of leaving large holes in flower petals and leaves.
How to Stop Them:
Fine crushed eggshells around plants or diatomaceous earth for slugs and snails.
Set up beer traps to attract and drown them.
Pick them by hand in the evening when they are most active.
7. Leafhoppers
Leaf-hoppers are small wedge-shaped creatures sucking up plant saps to cause yellowing and curling in leaves, and they can also be potential carriers of diseases to the plant.
Harm Reduction:
Introducing the beneficial insects into an area, such as ladybugs and lacewings.
Insecticidal soap treatment or neem oil to the plant will do.
Clear areas around with weeds that emerge as breeding places.
8. Earwigs
Earwigs are generally nocturnal insects munching on flower petals and their foliage, leaving ragged holes in plant tissue.
Stop Them:
Collect earwigs inside a rolled-up newspaper overnight.
Add diatomaceous earth around the flower beds.
Use insecticidal spray application as a last resort.
Final Thoughts
Observations have to be very watchful regarding protection against all kinds of insects to which flowers will be affected and methodical preventive and cure caution. An early pest identification, coupled with an eco-friendly method of control, would keep a healthy vibrant garden yet harm the best insects and pollinators the least. Of course, when the case escalates into severe infestations, a gardening expert might be necessary to provide further advice on plant pest management.
