If you are reading this, then you have read the above review of some of the best insecticides. However, picking one insecticide might be a little tricky and a little bit confusing. You have some options, and it’s challenging to choose the best one which matches your needs.
First of all, you should know what insecticide is because of many people confused with insecticides, pesticides and fungicides and they are very different. These three forms are interchangeable and use to control pests and plant-based diseases. However, they have different uses.
What are Insecticides?
Insecticides are pesticides used to control, kill, repel, harm or mitigate certain types of insects. However, they work in different ways; some directly attacks the nervous system, while others may damage their exoskeleton to repel them.
There are different types of insecticides in the market. Some are synthetically based, that contain toxic chemicals which can be harmful to humans, pets, plants, flowers, land, and the environment. On the other hand, some are botanical insecticides; they contain neutrally occurring chemicals extracted from plants and minerals. These insecticides are non-toxic and safe for humans and pets but harmful to insects.
These naturally occurring chemicals are Spinosad, Pyrethrin, and Neem Oil. However, some botanical insecticide may also use essential oils to repel insects like cedar, lavender, eucalyptus, pennyroyal, citronella, rosemary, peppermint and soybean oil. For example, Bonide BND210 Insecticide; it contains a superior type of paraffinic mineral oil to kills insect.
Here we listed some naturally-occurring chemicals that are mostly use in botanical insecticides.
Spinosad is a natural substance extracted from a soil bacterium and is highly toxic to insects. It is a mixture of two chemicals called spinosyn A, and spinosyn B. Spinsoad has been registered in over 80 pesticides products by the US Environmental Protection Agency, since 1997.
It is fast-active and highly effective against a wide variety of pests like spider mites, mosquitoes, thrips, leafminers, ants, whiteflies, and many others. It quickly kills the insect comes into contact by directly attacking their nervous system.
Pyrethrin is another naturally occurring insecticides extracted from chrysanthemum flowers. It is ideal for organic gardening because it is non-toxic and quickly disappear from the plant after demolishing the insects. Moreover, you can also use it on pets to control insects like beetles, flies, fleas, and ants.
Insecticides that contain Pyrethrin are highly effective and work quickly to knock down all the pests as soon as they come in contact. However, pesticides often contain a small amount of Piperonyl Butoxide, a toxic, non-organic chemical with it that makes the product more effective.
Neem Oil is a naturally occurring pesticide which is extracted from the fruit and seed of the Neem tree. It is yellowish-brown and has a bitter taste with a garlic sulphur smell. It is a highly effective insecticide use to kills or repels destructive insects and mites like aphids, whiteflies, snails, mealybugs, cabbage worms, gnats, moths, cockroaches, flies, mosquitoes and many other similar insects.
This compound control pests by ceasing their growth, prevent the larvae from maturing, intrepid mating behaviours and sometimes by coating the oil in the breathing holes of insects and kill them. However, it is non-toxic to birds, humans, and pets. Studies have shown that there is no cancer or other disease-causing result from its use. Moreover, Neem oil also has a dual function in the vegetable garden, both as a fungicide and pesticide.
Features to Look for in Insecticide for Gardens
Before buying an insecticide, it is crucial to consider some features like organic vs chemical formula, targeted pests, duration of efficacy and safety of the plant.
Organic vs. Chemical
The active ingredients in organic insecticide are extracted from natural resources such as plant, mineral and bacteria. They are highly effective against bugs but non-toxic to human and pets. So, consequently, you can use them for your home garden and pets to controls insects.
Although many of these may kill some beneficial bugs, but their short residual activity reduces the collateral damage. However, Organic insecticides are relatively expensive with a potential need to apply multiples time to eliminate the pests.
Chemical insecticides are derived from harsh chemicals and are typically faster, long-lasting, and cheaper than organic pesticides. They kill both beneficial and harmful bugs causing collateral damage. Moreover, they are highly toxic to animals, land, and environment. Therefore they can cause short term adverse acute as well as long term chronic health effects.
Before you go and buy an insecticide to eliminate unwanted insects from your garden, you’ll first need to learn what kind of they are. For this purpose, scrutinize your plant and notice the physical appearance of the insect you come across. Then it would help if you went through internet research or consult a horticultural specialist to get more information about the pests and the insecticide you need to get rid of them.
When insects are present at their growing stage or fully grow, it may be control by insecticide when they come into contact. But when the insect is at developing stages, the egg protects the insect from pesticide, and the problem resurges after a few weeks. Therefore, to eliminate insect, it is essential to use a long-lasting insecticide which can kill eggs of the insects. Otherwise, frequent applications will be needed to eradicate these destructive pests.
Although organic insecticides are gentler than chemical insecticides, some may contain potent ingredients that are not good for certain plants and animals. Many plants become weaken or even die if organic pesticides are used in too high concentration. Therefore, you’ll usually read the label to find out what sort of plant product is designed.
Liquid, Granular, and Dry Dust Application
There are three types of insecticides applications. Each has its pros and cons. Therefore, it is imperative; you should know what kind of application is best for you. Liquid insecticides are fast-acting, readily deliver the active ingredients to the problem after application. They are straightforward to use, spray liquid insecticide directly on the infested plants roots, stem or leaf to control insects and pests.
Granular is broad-spectrum treatment insecticides, efficient to treat soil level garden pests. They are straightforward to apply, sprinkle the granules on the soil infested with pests. Granules insecticides are very useful, but they also destroy good bugs.
Most of the dust insecticides are broad-spectrum treatments, but they are tricky to apply, especially on the lower leaves. However, gardening duster would be helpful to distribute the dust over the plant efficiently. Furthermore, they are easy to store, have a long shelf life and work effectively against the bugs.
By now, you not only have a great idea about insecticides but also know how they work and what points are taken into consideration when buying an insecticide for your garden. The guide outline will help you in purchasing the best insecticide to eliminate all the destructive insect not only from your yard but also from your house.
