Many people can't figure out how to get rid of those pesky little ants. If you're one of these people, this is for you.
Step 1: Obvious and Not So Obvious
Now, if you are trying to get rid of ants that are indoors, call the exterminator or buy some of those cheap little traps. This instructable is on how to kill outdoor ants.
My first way can be somewhat expensive, but very effective GASOLINE. If you pour some gasoline on ant hills they will quickly die. But money doesn't grow on trees (maybe someday) so the next few steps are much more cost efficient.
Do NOT attempt gasoline method in dry conditions. I am not responsible for what you do.
Step 2: Boiling Water
I find that the best way is to pour some boiling hot water (be careful) on ant hills. They go crazy and you will soon have more for the kill. You can sometimes destroy many ants with this method, but it's really great to do before putting store-bought poision on them.
Step 3: Alternate Methods
There are more ways to kill ants, some of which involve little kids, bb guns, paintballs, shotguns, waterguns, fire, chemicals, and steel toe boots. There are many methods of killing ants that you can do with these items. Please be careful with this step because although they may be fun, they can be dangerous, so handle with care. OR you can be fairly average and buy some ant poision.
But, we are trying to find easy and cost-efficient methods. Please be smart and realize there are a lot more ideas out there. Hopefully this just jogged your memory to think up some real creative idea. Be safe.
