Control Pests From Breaking Into Your Gardens

Unwanted insects in your garden are just that: unwanted. Unwanted insects may eat and destroy your crops, something shared by any farmer or home gardener. Organic horticulture is a means of controlling unwanted insects naturally, without the use of dangerous pesticides. There are many ways to control garden unwanted insects naturally that are also cheap, easy and good for the earth.
                     





Protect your organic soil and beneficial insects
While pesticides may eliminate the pest, they most often cause more harm than good. Unfortunately, many home and commercial gardeners are unaware of alternatives to pesticides. That’s because s are a big part of our culture. Reaching for a quick fix—albeit a dangerous fix—is a deep seeded and detrimental habit.

Yet apart from damaging the soil and being a health hazard to people—including our children—pesticides present a major problem. They eradicate species indiscriminately, causing helpful garden co-habitants to disappear along with the harmful ones.

An organic garden with beneficial insects
Indeed, the fact remains that not all insects are unwanted insects. Any kindergartner can tell you that bees help flowers. He or she could also tell you that a ladybug is good luck. But more than just good luck, ladybugs are a highly helpful natural pesticide to have in your garden, feeding on a myriad of insect unwanted insects including aphids if you ever see little alligator like insects around your garden, leave them be! These are the larval stage of ladybugs. Obviously, s are not as intelligent as your average kindergartner—they kill bugs on a wholesale level while upsetting ecosystems and ruining your plants as well as your soil.

Are your garden pests resistant to pesticides?
Commercial farmers today have a strong reliance on pesticides. Large companies sell pesticides to farmers who use them on their crops. Over the years the unwanted insects become resistant to the pesticides and increasingly larger amounts must be used. So it is that the farmer pays more and more money and dumps more and more of them onto his/her crops-our food. The result is a coated crop and a pesticide resistant bug, a crop that is more susceptible to the insect pest.

Are you harming the local bird population?
Recent studies have been conducted concerning pesticides’ effect on local bird populations. Birds eat the insects, which have ingested the pesticides. Because the pesticide is an indiscriminate poison, the bird is targeted as well. Furthermore, if the birds do not immediately disappear, their eggshells become thinner and thinner and often break when parent birds sit on the eggs. This is a huge problem with bald eagles in North America. With no insects and no birds those predators which live off of the birds disappear too, causing a huge disruption in the local ecosystem which is never beneficial to growth of any kind.

Birds eat insects!
Encourage birds to come into your garden by placing a bird bath in the garden and by planting plants that will attract birds such as sunflowers. There are even perennial sunflowers that not only attract birds year round but, can also be planted like a hedge and repel deer and other animals. Helianthus maximillani.

Natural pest control is rooted in a vigorous, balanced ecosystem. Years of pesticide use may be so disruptive to a local ecosystem that the land may become unusable after only a few years. They remain in the soil and become more concentrated with each year of use, eventually rendering the soil unable to produce vigorous plants.

The soil can heal
However, there is hope. Some products like methyl bromide can be amended by simply adding organic matter to the infected soil. The result is addition of the organic portion of this pesticide to the organic matter that you already added and liberation of the bromide ion. At the very least, you can add organic matter to a laden soil to simply dilute the concentration. However, you can also look up the MSDS online for that to learn how to amend it.

Organic alternatives to pesticides
There are many natural, organic alternatives to pesticides that are more long lasting, safe, vigorous and generally effective.

One of the simplest pest control devices is a barrier. By covering a row of crop with a light netting (which allows the sunlight to come through) flying unwanted insects are effectively kept away from the plants. These are generally used for food crops. Cabbage can be protected from flea beetles and green beans from Mexican Bean Beetles.

Another simple method of pest control for a small garden is handpicking. Many slugs and Hornworms can be handpicked off of plants with great success. Drop unwanted insects into a dish of soapy water to kill them. Certain moths and bugs can be knocked out of trees with a stick; allow them to fall onto a large piece of cloth so that they can be gathered and, later, submerged in a soapy solution or incinerated.

Beneficial Insects Will Control the Bad Insects
Some insects like the Ladybug and the Green Lacewing are called beneficial because they are the good guys who are on the hunt for the bad guys that are feeding on your plants. Here is a list of beneficial insects, with links to where they are offered by an Earth friendly distributor.


Green Lacewings Chrysoperla carnea 
Green Lacewings

Green Lacewings are an all purpose beneficial insect that feed on insects such as aphids and other insects that will come and feed on your plants. Green Lacewings are perfect for a backyard garden, larger garden, or a greenhouse.

Easy way to get rid of slugs and aphids!
Certain varieties of plants are more resistant to insects. Some research into the types of plants you grow and the unwanted insects common to your area could prevent a lot of pest problems. Also, some plants themselves are pesticides. For instance, planting tobacco around your vegetable garden is an excellent way to discourage slugs and aphids!

How native plants can revive your garden
Buy local transplants to avoid bringing non-native unwanted insects into your garden. Add mulch and other simple barriers around your crops, check your garden regularly. Healthy plants are naturally more resistant to predators; just like having a strong immune system. All of these methods are natural and easy preventative measures to help you obtain a pest free garden.

If your preventative measures did not work, there are many, natural and organic plant sprays that can control unwanted insects. A mixture of Petroleum oil and water sprayed onto a plant is a natural pesticide that has been used effectively for hundreds of years. Many oils, shells and plant extracts can also be used as safe, effective, natural pesticides.


Natural pest control is a safer and, ultimately, more effective means of keeping a vigorous organic garden. With a little more knowledge it becomes obvious that the use of non-organic pesticides is not only ineffective but dangerous and irresponsible. By understanding your native habitat ecosystem and working in partnership with establishing a balance of beneficial insect predators such as ladybugs, praying mantis, and birds, as well as planting species that naturally prohibit invasion by unwanted insects, you too can have a vigorous garden by working in partnership with your garden.

Do We Need Insects For Our Garden?

10 Beneficial Insects For Gardening

1. Aphid Midge: These insects look like a delicate, small wasp. The larvae eats more than sixty varieties of aphids from the garden. You can attract them by growing plants with a lot of pollen and nectar.

2. Big-Eyed Bug: This is a fast-moving bug with large eyes and very small black spots on it’s head and thorax. They are usually found in field crops and orchards. The big-eyed bug eats leafhoppers, spider mites, plant bugs, aphids, and small caterpillars. This bug is a real asset to gardening.

3. Ladybug (Coccinellidae): The ladybug ranges in size from 1/16 to 3/8 inch and have round red, orange or yellow bodies with black markings. They prefer gardens that have a large amount of pollen and nectar-producing flowers. The ladybug is fond of aphids, mealybugs, small insects and scales. The Mexican bean beetle is related to the ladybug but is not beneficial.

4. Minute Pirate Bug: These bugs are 1/4 inch long in adulthood and feature a black and white pattern. Fast-moving like the big-eyed bug and attracted to gardens where goldenrod, yarrow, alfalfa, daisies, and other flowering, pollen-producing plants are grown. They eat small caterpillars, thrips, spider mites, insect eggs and immature leafhoppers.

Insect Spray Warnings And Alternatives

All of us want to protect ourselves from anything that will harm us, no matter how small it may be. Mosquitoes, bugs and other small insects that fly or creep around our house are just some examples of those small beings that can pose serious danger to our health, especially to the young ones.

That is why almost all of us have resorted to having the insect sprays and repellants easily found in the shelves of our favorite grocery store. For quite a long time, these sprays have been the most effective method of getting rid of those pests in our house. However, as technology progresses and new studies have been made, these commercial sprays and repellants were found to be as harmful as the pests their trying to get rid us of.

Chemical Contents on Insect Sprays:

One kind of chemical that have been present in insect sprays is the lead arsenate. Lead arsenate is an inorganic compound of arsenic and found to be useful in the purpose of killing pests. However, this chemical is highly toxic especially to organisms that it is not meant for. It also persists in the environment even after several years of not using them.

Chlorinated hydrocarbons, though found effective against mosquitoes causing malaria and fleas, have serious drawbacks also. First of all, other insects like houseflies were found to be resistant to this chemical. Also, DDT or dichloro, diphenyl, triochloroethane, one of the chemicals based on hydrocarbons, was found to be fat soluble. Those who are heavily exposed to this chemical most likely have concentrations of DDT 1000 times higher in their fats than in the blood. Although, it may not pose any real harm, it might eventually lead to some complications.

Organophosphates are very toxic chemicals that are also found in some insecticides. Parathion, an example of an organophosphate, is actually 30 times more poisonous than DDT. Each year, since it was developed during the time of World War II, these organophosphates poison thousands of people throughout the world, and even kill them. Those who are taking care of these victims are also in danger. The excretions of these patients or even vapors coming out from them are enough to poison a human being.

Infertility in adult men may be caused by several factors. However, recent studies show that exposure to insecticides have an effect in male infertility. This is because of the chemical chlorpyrifos found in these sprays. When exposed to chlorpyrifos or its metabolite, it may lead to reduction in the levels of testosterone in men.

Until the year 2000, this chemical, chlorpyrifos, had been the most common insect spray used in residences. After the results of the studies were released though, the Environmental Protection Agency prohibited its use in residential areas to prevent children from being exposed in that harmful chemical.

How to Understand the Label

Since this commercial product is known to have chemicals in it, we should understand what the label tells us to be safe. We need to know the toxic potential of these insect sprays. Since these chemicals can prove to be lethal to humans, we must know the acceptable level that is safe to humans. The unit of measure of lethality is called the lethal dose 50 or LD50. The lesser the LD50 value, the more toxic the chemical is.

Alternatives

This information about the commercial insect sprays may be disturbing. But the good news is, there are several alternatives also available in the market that are much safer to use. You just have to read the labels carefully to know which one is better.

These alternatives are those that are made from organic components. There are some that are made from natural blend of plant extracts and oils. Others are either alcohol based or made from hot spices to repel insects. Most may not be aware but nicotine can also be used as insect repellant because it is extremely toxic to these harmful pests. And nicotine as insecticide has been widely used since 1880s. Miracle II is reported as effective on insect cleanup

Insect sprays are really important for us, especially if we have children around the house. We always rely on these products to keep harmful, little insects away from us and prevent diseases caused by them. However, we should also be careful in choosing the right product; else, we might end up being more harmed by these things that should protect us.
