Picture of How to Get Rid of Ants (Outdoor Version)
This is a modified version of this link. I do not claim this as my original version, but this is how I made mine so I could put them outdoors where my ant problem is/was.

Safety Note! This is very important, so I ask that you please pay attention to this before performing this Instructable. Borax, while used in many things as a helpful additive is a very nasty poison. This instructable assumes that because you now know this you will conduct yourself accordingly. I did some research and have found that one spoonful of this stuff *will* kill you. Half a spoonful is enough to kill a child or small fuzzy animal. So I ask that you please be responsible while making this instructable and keep track of what else is eating it. If you make some Borax Jelly and eat all of it, I am not responsible. After all, the box tells you not to, and I've advised against it so you're on your own if you keep reading!

On a better note....

Update: Rained all day and jelly stayed where it should have! But I do not know if the solution was diluted or not. Will keep this updated as things go by.

This is a great Instructable, but you need to add a main image of the final project to the intro step. Please do that and leave me a message when you have so that we can publish your work. Thanks!

If you mix sugar & yeast (one for one) and place outside near where they're coming in it will kill them and won't hurt anything else that might eat the mixture.

You eat Boron every day, it is in salt water, bones, most processed food, hand lotion, hair products, cleaning products ect. The 20 mule team comes from Boron, California at he safest mine in the United States, it doesn't absorb through skin and you would have to inhale so much of it you would probably die from suffocation at that point anyhow. Borax is a natural mineral derived from a natural salt. You are confusing borax with boric acid, they are not the same. You can make boric acid with hydrochloric acid mixed 1 part per 4 parts of borax. It is deadly to animals if they consume about a cup full on average, a human would have to intake almost an entire bag to reach lethal amounts. When you research, use google scholar not google.com , that's insane. People who write these blogs always use that. Secondly , borax isn't really that effective against red ants, you literally have to dig in their mound and pour large amounts of it in. You are better off using boiling water. You can read that baking soda works, that ants have a natural acidic cover to their bodies but that not true either. Get a single ant and put him in a pan of baking powder and see how long it takes him to die. Just as long as the ant in an empty bottle. The truth is there are few 'natural' ways to kill ants at the mound that do not involve fire, poison, or some sort of extreme heat/cold treatment. Corn meal isn't it either, Equal +peanut butter mixed with vinegar does work...the issue is ants hate vinegar...water and equal does not work nearly as well. Anyhow, Borax is not deadly, its a level toxin...what else is level 1? Salt for one....

inside the house i use lysol spray it kills them & stops the trail

I just throw corn meal down on //near ant hill or openings and they are killed off and no other ill effects. Much safer for other animals.

 I've read that ants loosely fall into one of two categories: they are either 'sugar ants' or 'grease ants. A sugar ant will go for your jelly or syrup or any sweet substance, while the grease ant is attracted to the savory.
I've read that in many places so it must be true. It must also be true that the ants at my house are a rare or even unique species as they are utterly inconsistent in their tastes. They seem to be attracted to anything that might piss me off.
A few years back I bought pure borax. I meant business. But I chickened out from using it, the warnings, like yours, were just too scary for me. The bottle still sits on the highest shelf in my laundry room.
I've come to realize that as long as I have a maple tree with aphids, I'll have ants (they actually nurse, or farm the aphid stock to keep themselves in aphid honey) I just don't get why they won't build their nest(s) in or under the tree instead of under my siding.
i use tuna oil, the oil you drain from your can of tuna before eating it
The Dark Ninja (author)  Galonii4 years ago
That's an interesting idea! I think I'll try that on these buggers!
The Dark Ninja (author)  Birdy Jane4 years ago
LOL! I totally agree. Even after we continue to wage war against them they continue to invade my house some how. Not as bad as they used to be, but still have the occasional visitor. GRRRRRR

From Wikipedia:

Based on mammalian median lethal dose (LD50) rating of 2,660 mg/kg body mass, boric acid is poisonous if taken internally or inhaled in large quantities. However, it is generally considered to be not much more toxic than table salt.[4] The Thirteenth Edition of the Merck Index indicates that the LD50 of boric acid is 5.14 g/kg for oral dosages given to rats, and that 5 to 20 g/kg has produced death in adult humans. The LD50 of sodium chloride is reported to be 3.75 g/kg in rats according to the Merck Index. Long term exposure to boric acid may be of more concern, causing kidney damage and eventually kidney failure (see links below). Although it does not appear to be carcinogenic, studies in dogs have reported testicular atrophy after exposure to 32 mg/kg bw/day for 90 days. This level is far lower than the LD50.[5] According to boric acid IUCLID Dataset published by the European Commission, boric acid in high doses shows significant developmental toxicity and teratogenicity in rabbit, rat, and mouse fetuses as well as cardiovascular defects, skeletal variations, mild kidney lesions.[6] As a consequence, in August 2008, in the 30th ATP to EU directive 67/548/EEC, the EC decided to amend its classification as reprotoxic category 2 and to apply the risk phrases R60 (may impair fertility) and R61 (may cause harm to the unborn child).[7][8][9][10][11]
Just to make sure you all read that...:

Long term exposure to boric acid may be of more concern, causing kidney damage and eventually kidney failure (see links below).

So yea, maybe not that bad, buy do have a care! It seems it can have some adverse health effects long before death.

is that a picture of a Trojan ant?! i dont think that old plan will work on them.
The Dark Ninja (author)  REA5 years ago
Why, yes it is! And you're right, the old plan didn't work on them. They're the real reason Rome burned...
akayaker5 years ago
Actually i like the photo where you have the nail half way through the cap. If you use a longer nail the upper half would provide a nice little handle to push them into the ground with. This would eliminate your need for a stick (step 5) to push the baits into hard earth.
The Dark Ninja (author)  akayaker5 years ago
That's a really good idea actually!! Thanks for the tip. This year we dont have much of an outdoor ant problem, but I'll remember this if I have to create my baits again. Thanks!

How to get rid of ants in one word: Flamethrower.
or put some gasoline in and near the ants nest, then throw inside a lighted up match
only if you can reach the queen :) otherwise you get only the worker ants.
It heats up the ground enough to kill it even if you don't actually burn it.

HOLY 1337 ANT KILLER!....too bad your 1336 <()>
OMG!! Deadly Ants
The Dark Ninja (author)  rusty13jr6 years ago
Lol thanks man. Speaking of 1337, I thinking of starting a website along the lines of "My [insert noun here] is more 1337 than you!" Like we did for the "My ping is more 1337 than you"... anyways, thats off topic. :o)
merijnvw5 years ago
Borax isn't that poisonous, the the highest dosis for a 80 kilogram person is 400 gram, so kitchen salt is more poisonous.
wow, i dont know where your info is coming from, borax will not kill u or small animals or children w/ the amount you are talking about.. i have been consuming 1/8th teaspoon of borax diluted in a quart of water.. actually i use green tea.. and i consume more water thru the day etc.. for the last 3 years.. my skin is healthy, my hair is soft, my feet are fungus free, and my digestion at age 42 is that of a 17 yr old.. i eat hot peppers, cucumbers, onions etc on a regular basis w/ no heart burn what so ever..borax is in bath crystals, edible plant pesticides, eye drops and various other things that a simple google search would illuminate you to.. also see this website http://www.earthclinic.com/Remedies/borax.html
and expand your horizons..
Do you use 20 Mule Team or pure borax?
The Dark Ninja (author)  Borat6 years ago
20 Mule Team, is there a big difference?
I asked because on that link you posted some people reference pharmaceutical-grade, pure borax. I have the 20 Mule and it says "not for drug use" apparently because it also contains surfactants and other laundering aids. I guess in these concentrations they don't harm you, though. Thanks again for the great tip.

beware of pets, wildlife and small children eating this stuff. Borax works by causing a solid blockage in the digestive tract and is a very painful and slow death.
The Dark Ninja (author)  wocket6 years ago
Thanks for a good note! Safety is always important. But, the solution is so diluted the chances of death occurring in a pet or child is slim to none. Unless they ate my entire batch of Borax Jelly I don't think it will cause them any harm. If there are any doctors/scientists/chemists/vets out there I would be interested to know just how much Borax it takes to kill a human, cat, or dog. That way I can quell the fears of my readers. (The box does say do not intentionally eat it...)
it takes just half a teaspoon to kill a human, so much less for small fluffy creatures.
The Dark Ninja (author)  wocket6 years ago
Woah, thats not very much! Do you have a link to the source you got that information from?
Not a link but I used to layout info from a medical research facility before the papers went into the general public and I remember reading it there. Scary stuff.
The Dark Ninja (author)  wocket6 years ago
Thanks again for your contribution. I did some googling and found that 1 teaspoon is enough to kill an adult, and that half a teaspoon will kill a child/small fuzzy animal. I was not aware that this stuff was so bad. Oh! I did find out that it is used as a food additive in France! I was like OMG!!!
Well this is scary then... (from Wikipedia) Food additive Borax is used as a food additive in some countries with the E number E285, but is banned in the United States. Its use is similar to common table salt, and it appears in French and Iranian caviar.
Ninja never type the last phrase replacer you typed. They type YWDTBMH (You Will Die Tomarrow By My Hands)
I'm going to have to disagree with any person that says half a teaspoon is as heinously toxic like botulinum. I mistook borax for non dairy creamer in college (the pure stuff for killing roaches). I drank several table spoons and it would just not mellow the taste of the coffee so I added more. After two days of the runs, I told my room mate that his creamer had gone bad. He informed me he had no creamer, but did have one of the huge wal-mart containers of borax for killing roaches under the sink with the other poisons. I called poison control and they said it was usually only a problem with children and that was the cause of the runs. They said it was not so toxic as to get too excited. I'd have had to eaten cups and did not need to go to the hospital. Perhaps you are thinking of BORON instead of the compound Borax. I'd have to look up the properties of each in the chem hazard book at work to give a real definitive answer. Remember SALT carries tons of crazy warnings about how it can elevate blood pressure and irritate wounds and sting mucus membranes and dry / irritate skin. Some of the warnings are just silly and hard to get a real idea about.. Borax is not very toxic to humans except for children.

I just confirmed with my researcher friend at Qld Medical Institute and they confirmed that it is quite dangerous... mostly for causing blockages in the gut. So you still need to be careful of pets, wild animals, children and ..well..anyone. :) Stopher, I guess we'll just agree to disagree.
Grey_Wolfe6 years ago
I might suggest that you place several small (half teaspoon, maybe) samples of foodstuffs (sans borax) in a location that is readily noticable to your ants. See which ones they respond to best and then alternate your bates between these items. Hope this helps. At least it would save you the trouble of making poisons that don't work.
JeremyA6 years ago
If you see the ant hills in your yard all you have to do is poor boiling water down them and that should take care of it. If needed repeat the steps more than once or every so often when you find a new one. I imagine it is a pretty terrible way to die but that is your choice.

If you're beset with only the brittle type of caps drill the hole in the cap instead of punching it with a nail. -Ray-
