Homemade Weed Killer Recipes

Having weeds in your garden and lawn really detracts from the look of your yard. Avoid using harmful chemicals by making you own weed killer. This is a guide about homemade weed killer recipes.

I have used the same method for many years now. Who would know that a huge mistake could turn out to be something useful years later? Maybe many ideas come to use that way, this one for sure did.

We were boiling shrimp with some friends when I lived in Louisiana. Being young and trying not to show it, actually taught me two things in the same weekend. One: do not put shrimp down the garbage disposal. Two: the hot mixture of spices kills your grass almost instantly! I do pretty much everything I can organically. If I still lived in the South where you boil shrimp or crawfish often, I would just use the left over water to pour on all my weeds. Since I have moved from there, now I make a special "brew" to kill all of those weeds, without hurting the environment. The ones that come up through cracks in driveway or close to the steps can't hide from this hot and spicy weed killer.

You take Cajun pepper (red pepper will do) and hot sauce, vinegar can also be added if you have extra. Bring it to a boil and pour directly on any area where you want everything to die. Be very careful not to get it on grass you want to stay alive. Anything this hot mixture is put on will die (ants don't like it either). If you make more then you use at any given time, put in bottle for next time. This works cool, but I have found it works faster when boiled, steaming hot. If you aren't wanting to see results immediately, know it works after mixture has cooled off.

I add a half jar of Cajun or red pepper and half a bottle of hot sauce to a large pot of water. You just know it is ready when your eyes are watering and the room fills with the smell of the mixture. I have added left over pickle juice, vinegar, even jalapeno juice to this, depending what is left over in my fridge or cabinets. This works and works well without hurting anything in the air; animals tend not to eat in that area but it doesn't hurt them.


If you do boil shrimp, crab or crawfish, please drain the water where any unwanted weeds are so you get double use out of something you would just throw away. At most markets that sell seafood, they have bags with seasoning already in it. I always ask this time of the year to let me know if any are past the selling date. A couple of times I got lucky and was able to get the boil in bag seasoning for a dollar. Any of these ingredients can be found at the Dollar Store. With no more worries about pulling weeds, maybe you will have more time to enjoy this beautiful time of the year.

Hi, wouldn't just boiling water from your jug do the same thing?

Instead of using harsh chemicals that can be lethal to children and animals and quite expensive, grab a nice big pot and fill it with water. Bring water to a rapid boil and pour on weeds. This literally fries the roots and the active growing weeds nearly instantly.

We would like to try the solution of vinegar, Epsom salt, and dish soap, but are concerned if it will kill everything. We do not want "volunteers" oaks, coffeeberry, etc. to be killed. Thanks!

First of all, you'd use regular salt; epsom salt is actually a plant food. Vinegar will render the soil sterile, meaning that nothing at all will grow there, maybe for decades (it stays in the soil). It will also render the soil sterile if a rain washes it to another place. It is best NOT to use it if you ever want anything to grow, ever. And yes, it will kill "volunteers." Just lightly spray the leaves with soapy (blue dawn dishwash soap) water on a really sunny day or use boiling water.

To kill dandelions, pour vodka into spray bottle and spray on dandelions on a sunny day. Add a little dish liquid for more stubborn weeds.

One can just pour hot water on plants to get rid of weeds. But, I wish people would really look at all the plants growing in their yards and ask why.

I feed all of our wildlife here in the yard. I have a feeder for peanuts for the squirrels, they make a mess with the peanut shells, so I got the bright idea of using them for weed control. I put them around the flowers, and have started using them around my vegetable plants.

I've misplaced a very effective recipe for an natural weed killer. It used Pine Sol as one of the ingredients. Would greatly appreciate if anyone is familiar with this recipe.

I love Pine Sol for everything. I make a house cleaner out of it in a spray bottle using 4 parts water to one part pine sol. I am now going to use the recipe above in the yard. Thanks! Robyn

I am looking for a recipe for organic weed and grass killer.

Hardiness Zone: 8a

Put it into a cheap $12 garden pump-sprayer & spray the area... Or you can pour it directly on to the ground. If your heat the vinegar up it works even better... The very best vinegar is a special stronger-acid type that's sold at plant nurseries, but any kind of vinegar will work.

Boiling Water:

If you may want to plant something there later on, you can simply use boiling water... It kills the grass & weeds, but won't keep the area from growing plants in the future. You can simply set up a propane camper stove outside & boil your water on it...

* Keep your animals inside while using the stove & watch out for your neighbors animals that may wander into your yard, you don't want them to be scalded!

Does anyone know where corn gluten can be purchased? I have been told it is used in Oklahoma, spread like grass seed. It apparently feeds the grass and kills the weeds.

You may want to read this and other articles before you spend time and money on corn gluten.

Vinegar. I read something about vinegar with a mix of epsom salts. But now I can not re-find the link! Shucks. But try looking it up on gardening sites that have a dot.ORG ending. That may help. In the meantime I will look again.

Vinegar works well as a weed killer. Put it in a spray bottle, turn the sprayer so it shoots out in a stream, and aim it at the bottom of the plant.

I've used bleach, but I don't like to because I doubt it's safe for the environment.
