Giardia is a microscopic parasite that can cause diarrhea, cramps, bloating, gas and fatigue. It is the most common cause of traveler’s diarrhea in the United States.
If your lawn’s soil gets water contaminated with giardia, it can get infested by this parasite, leading to destructive consequences for everyone who comes into contact with the soil or grass above it.
5 Ways to Kill Giardia in Soil
For giardia infestations in soil or grass, it is strongly recommended to get in touch with a professional at your local garden center. They’re equipped with the tools and chemicals needed to deal with this infestation.
Plus, giardia poses serious health risks so it’s best to leave this job to the professionals.
The following tips are for educational purposes only.
1. Use a Good Fungicide
A good fungicide is one of the best ways to kill giardia in soil. The most effective fungicides are those that contain copper, such as Bordeaux mixture (copper sulfate). However, it can be difficult to get the copper concentration high enough to kill giardia without killing your plants.
A better option is a synthetic fungicide called Subdue Maxx. It contains imidacloprid, which is a chemical that works by interfering with the nervous system of insects and worms. It also has an effect on giardia cysts, so it will help kill giardia in soil.
2. Use Beneficial Nematodes
Beneficial nematodes are microscopic worms that feed on giardia cysts and other soil-dwelling parasites like roundworms and threadworms.
They work well because they have no effect on humans or animals, but they do have an effect on parasitic worms and insects. You can buy them online or at some garden centers or nurseries.
Just follow the directions for application carefully to make sure you don’t harm your plants or pets when you apply them to your yard or garden soil.
3. Use a Fungus That Attaches Itself to Parasites
There are certain fungi that attach themselves to parasites like giardia cysts and roundworms and then release chemicals into their bodies that cause them to die off within 24 hours!
These fungi are called entomopathogenic fungi (literally “insect-killing fungi”) because they only attack insects and worms – not humans or animals – so they’re completely safe for use around people and pets! One of these fungi is called Beauveria bassiana, which comes from a group of fungi known as “fungus gnats” because they were first discovered infecting fungus gnats (which are actually tiny flies).
The fungus attacks the worm/parasite by releasing chemicals into its body that cause its cells to break down until it dies off within 24 hours!
This is one of my favorite ways to kill giardia in soil because it doesn’t harm any living creatures except for the parasites themselves! To learn more about this amazing fungus, click here.
4. Use the Right Amount of Fertilizer
If you’re fertilizing your lawn or garden, you can use a fertilizer that contains iron and copper to help kill giardia in soil. The right amount of fertilizer is important because too much can cause more harm than good!
For example, if you have a small area of lawn that has been infected with giardia cysts, it would be best to use a liquid organic fertilizer (like kelp) instead of an inorganic fertilizer (like ammonium sulfate). Organic fertilizers are better for the environment and they’re safer for humans and animals.
If you’re using an inorganic fertilizer like ammonium sulfate, make sure to only apply 1 pound per 1000 square feet (or 1 tablespoon per 10 square feet). Also, avoid using any kind of chemical herbicide on your lawn or garden until after you’ve killed off all the giardia cysts!
This will help prevent any harmful chemicals from contaminating your soil and harming your plants.
5. Use Compost Tea
Compost tea is made by steeping compost in water for several days so that it releases beneficial microorganisms into the water.
These microorganisms then colonize the roots of plants and help them grow healthier by improving their immune systems and making them more resistant to disease!
You can buy compost tea bags online or at some nurseries or garden centers. Just follow the directions carefully when making compost tea so that you don’t accidentally contaminate it with harmful bacteria or fungi!
I recommend adding 2 tablespoons of compost tea per gallon of water to your soil before planting new plants or seeds so that they have an easier time growing healthy roots without getting sick from parasites like giardia cysts!
