There are natural methods that solve the problem of flower and plant pests. Avoid using pesticides!

Flowers and potato

For those who like to take care of their indoor plants and have a talent for gardening, it is not uncommon to encounter a particular situation.

Small insects that do not bring any harm to humans, but are dangerous for plants, often find their way on the leaves and stems.

These insects, known as aphids or lice, can be a serious obstacle for those who have invested time, effort and passion in cultivating their home garden.

The presence of these parasites is a frequent occurrence and can easily derail all the hard work that has gone into creating a beautiful indoor oasis.

Fortunately, the issue of plant pests is not an impossible obstacle to overcome.

In fact, there are several methods and measures that can be put in place to eliminate these parasites in a simple and effective way. Below, you’ll find a comprehensive guide outlining everything you need to know.

Plant pests: what are they?

There are numerous types of insects that can pose a threat to plants, and aphids are among the best known.

These hemipteran insects are typically tiny, measuring between 1 and 3 millimeters in size, with a delicate body structure.

They may or may not have wings and have a buccal apparatus capable of piercing and/or sucking fluids.

Aphids are harmful to plants because they feed on the sap of both cultivated and wild plants, and are particularly harmful to broad beans and apple trees.


Owning roses can become a nightmare due to their tendency to spread and affect other plant species nearby.

Detecting an aphid infestation is a relatively easy task that can be done with quick visual inspection.

These pests consume plant sap, which affects the overall health and liveliness of foliage, including color and shape.

A superficial examination of the buds and leaves with the naked eye is usually sufficient to identify the problem.

However, it is important to note that their appearance can deceive growers. While they usually appear in brown, yellow or black hues, some aphids can be green, which makes them more difficult to detect since they blend perfectly with the leaves to which they attach.


There are various risks that fans of domestic crops should consider, and aphids are not the only one.

Caterpillars are another risk that should not be underestimated, as they can quickly consume entire plants or branches.

Typically, they start by nibbling on a small leaf and then proceed to other parts of the plant and nearby specimens.

This type of pest prefers tender and sweet foliage, especially basil and lettuce leaves.

Caterpillars are difficult to spot because they often blend in with the plant they feed on, having a green color exactly identical to their host.

Bedbugs pose a real threat to plants, especially with the Asian bed bug posing the most serious threat.

Despite its small size, this pest can have a catastrophic effect, especially for farmers.

When present, it is important to focus on fruit plants, such as peaches, pears and apples. The Asian bed bug is distinguished from its European counterpart, in that it affects not only the leaves but also flowers, vegetables and fruits.

The insect causes necrosis, sucking sap from plants, eventually contributing to the wilting of the plant.

The attack of the bed bug at the base of the buds can lead to the desiccation of the plant, with profoundly negative repercussions on the success of the crop. It is worth noting that the Asian bed bug has also spread throughout Europe.

Cochineal, red spiders and whiteflies

The impact of cochineal should not be overlooked, a parasitic plant that has the ability to propagate only in certain climatic conditions.

This tiny insect particularly loves hot, humid climates and tends to disappear when it rains.

However, the proliferation of mealybugs over time can lead to a noticeable decrease in the structural integrity of the plant.

Whiteflies, native to tropical regions, prefer warm and humid climates, similar to the mealybugs mentioned above.

Plant pest

They are a common problem in greenhouses and areas with lakes and are known for the damage they cause to lemon plants.

However, for those with small gardens that include ornamental plants such as begonias, geraniums, or orchids, whiteflies can be a big problem.

The formation of honeydew, a sugary substance that yellows the leaves where the whitefly rests, is a clear sign of their presence and can cause the leaves to fall.

Red spiders, although harmless to humans, are actually tiny mites that fall into the category of parasitic insects and can cause significant damage to the fruits and ornamental plants they feed on to survive.

It is important to note that animals are not the only threat to plants, as they can also be significantly affected by fungal infections.

An example of such a disease is powdery mildew, also known as white powder, which manifests itself as a powdery substance that coats the plant, similar to talc.

This affliction is typically limited to outdoor garden plants and does not affect indoor houseplants.

Powdery mildew is caused by spores of a specific type of fungus called powdery mildew, which is invisible to the naked eye and can be spread through wind dispersion.

Avoid the use of pesticides

At first glance it may seem logical to use chemicals, such as synthetic pesticides, to effectively eliminate pests and prevent their continued growth.

Farmers use chemical agents to protect their crops from animals that pose a significant threat to their economic stability, and the use of these agents is strictly regulated by law.

The problem lies in the well-known negative effects of these substances, which affect various levels of society.

These pollutants are incredibly harmful to the environment and can infiltrate the soil, subsequently seeping into groundwater.

This poses a significant threat to all living organisms, especially over a long period of time.

The negative impact of pesticides, especially systemic ones, on the human body has been repeatedly attested because of their residues that remain on agri-food products.

Luckily, there are safe and effective natural remedies that we can use from the comfort of our home and the next chapter will illustrate some of these options.

Natural treatments to eliminate pests from plants

One of the most popular remedies to deal with this problem is the use of neem oil, a natural extract derived from the pressing of the seeds of the Neem tree.

The key component of this oil is azadirachtin, which effectively eliminates certain pests such as aphids, without at the same time discouraging the presence of pollinating insects, such as bees, essential for the overall health of flowers and plants.

Another advantageous resource in pest control is Bacillus Thuringiensis, easily available on the market.
