Checking Bed for Bugs

Most bed bug traps and tests can cost $ 50 or more, but this DIY trap is so simple and inexpensive that researchers who came with him want people to treat themselves. Ideally, you’ll catch the early stages of an infestation, when the animals are easier to remove. All you need is the sugar, water and yeast.

Here’s how to make one, according to this article NatGeo:

Fill an old coffee cup ten tablespoons (150 grams) of sugar, two tablespoons (30 grams) of yeast, and one and one and a half liters (pints of water), and put it in the middle an overturned bowl of dog. Here is! You have just a bug detector beat the others on the market and is much cheaper.
For clarity, all they suggest is mixed in a bowl: and then put the container in the center (Note the original experiment actually a soda bottle tilled for this, it would be more logical than a cup of coffee used) empty the bowl until / / the dog upside down. The reaction of CO2 in large bowl to attract insects, and when they get into the dog dish upside down, the sloping sides will catch bedbugs as a pit so you can not get out. According to the study (link below) as they sprayed a little glue on the sides of the container only to increase the efficiency of the trap.

In all cases, the yeast eats the sugar and releases carbon dioxide, just as humans do when exhale. The gas is also used to find bugs sleeping guests and are very good for monitoring carbon dioxide, even over long distances.

DIY trap will not kill bed bugs, but catch them, and entomologists from the University of Rutgers Narinderpal Singh Changlu Wang and Richard Cooper all agree that is able to detect early enough signs of infestation to deal quickly and easily. Researchers have even put their test against the first commercial version and have found that their method was more effective to keep the bugs trapped inside, so its positive result does not escape, suggesting that all is well.
