The Vegas roach trap or Las Vegas roach trap refers to the serendipitous discovery, in Las Vegas, of a cockroach trap consisting of a jar, coffee grounds, and water, placed against a wall. Reported as extremely successful in eliminating cockroaches by Las Vegas local news and the KVBC bugcam ^*, the homemade trap is made from any glass jar containing used coffee grounds and water. Placing the mouth of the jar next to the wall, the roaches are able to crawl up the wall and into the jar, to drown, or at least never escape since they are unable to climb the glass walls. Apparently, only cockroaches are attracted to it. The Vegas roach trap is so called by the popular name of the city of its discovery.

Construction

---

Construction of the trap is extremely simple. The steps outlined as follows:

1. Find a glass jar, preferably a canning jar or pickle jar.
2. Next time you make coffee, dump the used grounds into the bottom of the jar.
3. Add some water - enough to barely cover the coffee grounds, a little more if your local cockroaches fly.

Your cockroach trap is now ready to catch some bugs. Lean it against the outside wall of your house so the cockroaches have a way to get in, and you're done.

A modification to the trap is to coat the outside of the jar with scotch tape or packing tape, which gives the cockroaches enough traction to climb up the side of the jar without using a wall, allowing placement of the trap virtually anywhere.
