Insect Killer for Vegetable Garden Buying Guide
Let’s be honest! Keeping insects away from your crops demands too much money. So much so that some gardeners prefer to invent their own formulas rather than spend a small fortune on those famous products that promise miraculous results.
Other people don’t buy them for the bad reputation they have. It’s proven that when dissolved and filtered through the ground, pest killers pollute water sources. Some products, not only kill insects, but everything that crosses their path.
Therefore, you should know very well the formulation of the insect killers that you use in your garden or you could be committing a magnicide to the ecosystem.
Many believe that chemicals to control pests cause cancer. However, not all insect killers have the same formulation, so it’s impossible to be sure that everyone has the same effect.
Anyway, the opinions are diverse and while some defend the chemical products, others opt for something more natural. Whatever your choice, it’s convenient that you know some basic concepts about insect killers before buying one.
Safe for Humans and Pets
Before applying any product in your garden, make sure it’s safe for humans and pets. Dogs, for example, love sniffing everywhere, especially the gardens.
Some products with systemic effect are so powerful that they can cause paralysis in squirrels and raccoons with just a contact. For that reason, don’t use a product without first knowing its composition.
Some chemicals can cause malformations in fetuses. To avoid complications, it’s wise to keep pregnant women away from crops sprayed with chemical insect killers.
Chemical vs. Organic
This is a common issue. No one can make a perfect decision about these options. So here is our discussion.
No one can deny that chemicals are more powerful and effective than organic ones. However, the great popularity of organic products has forced many farmers to change their pest control methods.
Today, most organic insect killers that are sold in the market are biodegradable and beneficial to the ecosystem. One of them is neem oil. This bitter substance is deadly in its purest presentation for all types of bad insects.
It kills surface insects, ground insects and flying insects. In addition, its aroma is unbearable for plagues, keeping them away from your vegetables. When it’s absorbed by the soil, it degrades and acts as a fertilizer.
Unlike other products, neem oil serves as an insect killer and fertilizer at the same time.
Another popular organic insect killer these days is Spinosad. Discovered in 1985, in a soil sample from a non-operational rum distillery in the Virgin Islands. This compound comes from the fermentation of some natural products by the action of the S. spinosa bacteria.
It’s a selective insect killer, because it only eliminates insects that feed on plants. The product, after ingested, kills between 1-2 days later. In adult insects, it has a lethal effect. In the larvae, it delays metamorphosis process.
By far, neem oil and Spinosad are the most efficient organic insect killers. However, there are other products that combine oils and extracts from edible species to protect small organic crops.
Some of these are garlic extract, fish oil and thyme oil. Products with these ingredients aren’t as effective and can even attract other pests. In addition, they can ruin fruits and vegetables when applied directly.
Range of Action
Some insect killers only kill. It doesn’t matter if the insect is good or bad. However, without beneficial insects nearby, it’s certain that your fruits and vegetables won’t reach full ripening.
You should make sure that the product you use only kills the insects that feed on your fruits and vegetables. Also that the pests that commonly attack your crops are within the range of action.
Some people end up regretting buying a certain insect killer, after knowing that it’s harmless to the greatest threat to their fruits and vegetables. If you’re going to use a product for the first time, make sure you know how many types of insects it kills and which they are.
The frequency of application of a particular product also tells you how effective it is. It isn’t convenient to buy a product that is too expensive to apply every day. If your vegetable garden is too big, you’ll end up bankrupt before harvest.
Some organic products have a residual effect that continues to kill for weeks. However, chemical insect killers can continue killing for months. In addition, they are highly soluble in water and kill insects that can eat the roots.
Obviously, for crops that are too large, the use of chemical concentrates is the only alternative. The application of such large volumes of organic pest killers is impractical and unsustainable.
The price is perhaps the main reason that forces farmers to prefer between one product and another. If it’s effective and cheap, it’s good. That’s how most of them think. However, those who think that way could be contaminating the soil and water sources without knowing it.
Organic products are safe and don’t contaminate water or soil. In addition, they degrade very fast. However, the most concentrated organic insect killers are also the most expensive.
Highly concentrated chemical insect killers only cost a small fraction of what the purest organic pest killer could cost. Neem oi, for example, is one of the most expensive natural products.
Obviously, the larger your organic crop, the more money you’ll have to pay in pest killers. For that reason, before opting for the natural path, you must calculate very well the money you’ll need.
Best Brands of Insect Killers of Vegetable Garden
