Not exactly life hacks, but shortcuts that can help computer users:
holding CTRL and pressing the arrow keys will move the text cursor whole words, instead of 1 character at a time. Also works with Delete and Backspace
CTRL + Home will move the cursor to the start of the file, CTRL + End to the end of the file or textbox.
Windows 10 users can use the Xbox bar to record their screens. By default, the shortcut is Windows button + Alt + R
For anyone that uses the sink to wash dishes, have a net/grid to cover the hole. Once it's full, just pick it up and dump the contents in your food trash.
You can use any type of soap to create barriers that ants will avoid. If you plug a hole with some soap (try a piece of soap bar that's wet/soft), the ants won't reopen it.
Cinnamon works wonders against ants. Just put a little down where they are coming in. They won't walk on it, and it messes up their ability to follow pheromone trails.
If you absolutely want to kill them for some reason, the liquid borax baits seem to work the best in my area. Just make sure they cannot be reached by pets or small children.
