Benefits of Beneficial Insects in the Garden

There are many beneficial animals that help keep pests away in the garden, promoting better plant growth. The beneficial insects can eat pests and thus free the plants. These garden helpers can be targeted by gardeners to protect plants from harm.

Which beneficial insects help in the garden?

With biological plant protection, the self-sufficient garden can be optimally protected without side effects quite naturally. Thus, beneficial insects can be used against soil pests or against insect pests. The little helpers can keep away annoying parasites and promote undisturbed plant growth. There are a variety of different beneficial insects that are helpful.

Unlike chemical control of pests, there can be no misapplication through biological use of beneficial insects. One well-known pest is thrips, which can be controlled with the help of predatory mites. Also known as fringed aphids, these insects can cause leaf damage to plants. Flower bugs or lacewing larvae can also be helpful in the fight against fringe winged moths.

The tomato leaf miner is a species of butterfly and a pest of tomatoes. ichneumon flies and pirate bugs can be used to counter this pest and prevent its spread, as it already controls eggs and larvae. Tomato rust mites also infest tomatoes. The stem of the tomato plant, and later the leaves and fruit, can turn brown when infested with this type of mite. It can be countered with the help of Typhlodromus and Amblyseius spec. Also not to be underestimated is the effect of fungus gnats, which can become a particular pest for agriculture if they occur en masse. This globally distributed species can infest various vegetables, mushrooms and ornamental plants.

Steinernema feltiae nematodes and Bacillus thuringiensis israelensis are helpful for pest control. Whiteflies belong to the aphids and like to infest houseplants and ferns. The fight against whiteflies is carried out with ichneumon flies and chalcid wasps. Meadow snails are relatively large insects, which can damage especially green areas and grain fields in case of mass occurrence.

Biological control of these insects is being tested by the “Tipula iridescent virus (TIV)”. Also to be mentioned are the mole crickets, which belong to the grasshopper family and can cause damage to agriculture. However, the mole cricket is endangered and highly threatened in some countries. The slug, on the other hand, is widespread and can infest gardens. Beneficial insects that eat slugs are many mice, birds, slow worms, frogs, toads and also ground beetles. There are also plum moths, a species of butterfly that can attack plums.

Parasitic wasps are the natural counterparts to this insect. Spider mites are capable of damaging plants. Houseplants are often affected, but there are remedies through a good indoor climate and good humidification of the air. The leaf miner flies can contribute to damage to plants by appearing en masse. A biological antidote is the ichneumon wasp. Aphids are small plant lice that are pests to crops and ornamentals. Unfortunately, practically all plant species are affected. However, counteraction can be achieved with ladybugs, hoverfly larvae, lacewing larvae and ichneumon wasp larvae. Caterpillar flies, predatory bugs and ground beetles are also helpful – soft-bodied beetles, spiders and birds can also be used successfully as countermeasures.

Where to buy beneficial insects?

Beneficial insects that are helpful against pests can be ordered on the Internet, although shipping is only at mild temperatures, because the beneficial insects may not survive transport at temperatures below 5 degrees Celsius and above 30 degrees Celsius. Often, the biological response to pests is similarly favorable to the chemical response, but it is much gentler on plants and nature.

Therefore, more and more garden owners are turning to biological beneficial insects to help the environment and nature. It is important to have a natural balance in the garden and to be able to feed the beneficial insects, a low level of pests in the garden should be accepted.

Garden targeted promotion with beneficial insects

It is important to create good conditions for beneficial insects in the garden. Beneficial insects should be given a natural environment in which they can thrive and multiply. After just a few months, a stable environment for plants and beneficial insects will result, where both thrive.

A varied and very natural garden design can be very beneficial to the small garden inhabitants and so small piles of leaves, copses, flower and wild fruit hedges help to maintain the habitat of small animals. An insect hotel for beneficial insects is also highly recommended.


Optimal living conditions should be created for the garden so that pests are on the retreat. This is done primarily with beneficial insects, which can quickly provide relief and establish biological balance. Beneficial insects can be ordered on the Internet and can be used specifically depending on the plant genus. This is often very close to nature and inexpensive.
