Glue-covered sticky traps are commonly used by pest control companies to capture mice. But it's also incredibly inhumane, since the mice often starve to death or chew off their own feet in an attempt to free themselves. While we don't advocate glue traps at Do Just One Thing, there is something you can do if you find a mouse stuck on one. All you need is a paintbrush and vegetable oil to free them. Pour a liberal amount of oil over the sticky part and use the paintbrush to nudge the mouse off the trap. Be sure to do this outdoors, where the mouse can recover in a warm area after you free it.

Whenever you fill your car with gasoline, always fill it all the way up. By doing so, you'll make fewer trips to the gas station and increase the fuel efficiency of your car. Also, when the pump clicks off automatically when your car's tank is full, don't remove the pump right away. There is about one-fourth cup of gasoline still in the hose line (that you paid for) that needs to work its way into your gas tank. If you wait about 15 seconds, you'll get every last drop.

One of the most important items to have in your home is a fire extinguisher. But fire extinguishers require maintenance to remain in working condition. Metal extinguishers have a gauge to determine if the pressure is in the proper operating range: If the needle is pointing to green, the unit is fine; if it's pointing to red, the unit is overcharged or needs to be recharged. The good news is that many fire departments have refill programs that will fix your extinguishers for a small fee. It costs significantly less than buying a new one, and the fire department will also recharge and inspect your extinguisher. If your local fire department does not offer the service, it should be able to recommend a company nearby that can do it for you.
