Are scale insects harmful to humans?  among these questions and others are what we are going to consider in this article.

Are Scale Insects Harmful to Humans

Scale insects are a diverse group of soft-bodied insects that produce domed scales and waxy coatings as a kind of protection.

Humans are not physically harmed by scale insects, although they can cause allergies in those who are allergic.

In truth, the Coccoidea insect family has a long history of human use in the manufacture of dyes and varnishes.

They are most commonly known as common plant pests, which is how they cause the most damage.

In this article, we’ll go over everything you need to know about scale insects, including how to properly deal with them if they’ve infested your plants and how to keep them from returning.

What Are Scale Insects and What Do They Do?

It might be difficult to define scale insects because there are over 8,000 species and sub-species.

However, there are some characteristics that this insect family shares:

• They’re tiny, measuring only a few centimetres in length.

• Males and females have unique characteristics, with females having soft, wingless, and limbless bodies and males having legs and wings.

• Females outlast males and remain permanently linked to the plant they feed on.

• After emergence, males only live for a few days.

• Scale insects get their name from the domed scales that the females dwell beneath.

• They generate a considerable amount of powdered wax.

• They are mealybugs’ relatives.
• They gorge themselves on sap.
• Honeydew, pleasant excrement that attracts ants and causes plant disease, is secreted by them.

Are scale insects harmful to humans?

Scale insects do not bite and are not harmful. They have a limited ability to damage humans.

Scale insects have been handled and even bred by humans for millennia.

This is because scale insects like the cochineal, kermes, and lac are utilized to make vibrant red dyes that are even used in food.

Shellac, a resin used as a wood gloss and food finish, is similarly made from the lac bug.

If someone who is allergic is exposed to these insects at a high level, the insects and their products may induce allergies.

Because of their feeding habits, scale insects are common garden pests.

There are at least 25 species of a scale insect in the United Kingdom.

Scale insects can harm a wide range of plants throughout the year because their preferred hosts and life cycles fluctuate.

For gardeners and growers who cultivate plants inside, in greenhouses or underneath, their detrimental effects on plants can be a genuine pain.

The Feeding Habits of Scale Insects

Here we will also see how to scale insects feed.

Scale insects have mouthparts designed to puncture a plant’s outer layers and drink its sap.

Females, who remain attached to the plant, are mostly responsible for this action.

A sugary sweet waste product known as honeydew is driven out of the scale insect as a waste product as the plant fluids flow into them under pressure.

Ants eat this sweet material while protecting scale insects from predation in a mutually beneficial partnership.

The scale insect’s feeding process can harm or kill plants.

An infestation of scale insects and their eating of a plant will hurt it in three ways:

1. Reduced development due to parasitism: scale insects are parasitic insects that deprive a growing plant of essential nutrients and minerals. As a result, the damaged plants lose height, leave, and may even die.
2. Plant diseases can be transmitted by scale insects because they breach the plant’s outer defences. Plants that have been damaged by scale insect feeding are more susceptible to a number of illnesses.
3. Honeydew is secreted by scale insects, causing a black powdery mould to form on the plants they feed on. Sooty mould is the name for this type of mould.

Scale Insect Infestation Signs on Your Plants

If you’re concerned about the state of your greenhouse or garden plants and want to know what’s causing it, the following symptoms could point to scale insects:

• Plants that are stunted or fading
• There are lumps on the underside of leaves, between leaves, and on plant stems that are shell-like or scaly. They are often brown, yellow, or white in colour and have a waxy varnished finish.
• A web of waxy white filaments covering tiny eggs
• the presence of sooty mould on the surface of the leaves.

Scale Insects in Your Garden: How to Get Rid of Them

Getting rid of a scale bug infestation is vital if you don’t want your garden or greenhouse to get overrun.

Following timely treatment to eradicate a scale insect infestation, avoidance of recurrence is required.

Here are the essential measures you must take.

Scale Insects: Organic Control Methods

• Scale insects on plants can be manually removed. Repeated topical applications of steam or rubbing alcohol can kill or weaken them.
• Scale insects can be organically targeted by ladybirds and parasitic wasps, which are natural predators. Birds can also assist in the removal of numerous scale insects. The nematode steinernema feltiae provides a biological control alternative.

Scale Insect Pesticide Control

Use pesticides with caution because they may harm your garden’s beneficial insects.

There are a variety of organic insecticides available, including:

• Winter wash with plant oil.
• Pyrethrum
• Omega-3 fatty acids
• Essential oils from plants

These can be sprayed on and are most effective in the mid-to-late summer when the scale nymphs’ physical protection is weakened.

The scale insects will not be removed by pesticide treatment; their carcasses will remain on the plant.

Have You Noticed: The only way to determine if they’ve been effective is if the infestation doesn’t get any bigger.

Scale Insect Infestations and How to Prevent Them

Scale insects or indicators of their existence should be monitored on susceptible plants on a regular basis.

Before introducing new plants to your garden, greenhouse, or home, they should be evaluated and quarantined.

This is a fantastic way to keep plants disease-free.

Adding it all up

When you consider how important scale insects have been to people throughout history, they are incredible tiny organisms.

Your prized plants, on the other hand, are the last place you want them to appear.

Despite the fact that these insects are not harmful to humans, keeping an eye out for them will guarantee that your plants stay healthy.
