With mosquito weather upon us and our wonderful little friends being carriers of several nasty things it would be good to have a method of trapping those little suckers. This works great, is inexpensive, and has no caustic chemicals that harm humans, pets, or plants.
Cut a liter plastic bottle in two pieces at approximately 1/3 of the distance from the end of the threaded cap portion (remove cap if still on bottle). The 1/3 portion will be used as a funnel. Add about two cups of water to the 2/3 portion of the bottle. Add a tablespoon of yeast to the water as well as two teaspoons of brown sugar (white sugar can also be used but brown is better). Stir the contents. Place the funnel portion of the bottle as shown in the above photo on the left. Make sure it seats tight in the larger portion. If it doesn’t you can use packaging or duct tape to seal it tightly. Make sure there is at least 1" between the top of the water and the bottom of the end of the treaded part of the 1/3 bottle portion.
Mosquitoes are drawn to the sweet ingredients within the mixture. They fly down to get a drink and can’t find their way out and are trapped. Eventually they tire of flying and drop into the water and die. Empty and replenish as required.
Make several to keep around your property and inside your dwelling.
Now all we need to do is get some people size and set them outside the White House and the Congress. They definitely are too dumb to find their way out.
Pixar’s A Bug’s Life was first released on November 25, 1998.

James Cook University researchers have found sex sells when it comes to luring male mosquitoes.
Senior Research Officer Brian Johnson and Professor Scott Ritchie set
out to make a cheap and effective audio lure for scientists collecting
male Aedes aegypti mosquitoes – the species that carries dengue and yellow fever.
They found a tone of precisely 484 Hertz, the frequency of a female Aedes aegypti’s wings, brought 95 percent of male mosquitoes to the trap.
Mr Johnson said the device cost around $20 and could be run by itself
for weeks. “We started with a cheap mobile phone and moved to an even
cheaper MP3 player. There are no harmonics, it’s a pure tone and very
simple to produce.”

Jurassic World director confirms how they obtained mosasaur DNA
Since it was first announced that the marine reptile mosasaurus will be appearing in Jurassic World, some have wondered if it would be explained how the film’s scientists obtained genetic material from such creatures. In the previous movies, it was established that dinosaur DNA was retrieved from mosquitoes trapped in amber that had once fed on dinosaur blood… but there aren’t mosquitoes underwater.
Today, Jurassic World director Colin Trevorrow provided an explanation, answering the question posed by a follower by posting a link to a news article about soft tissue and genetic material being discovered inside fossilized dinosaur bones themselves – no mosquito required.
This technique is briefly referenced in the original movie as well, and Crichton touched on it in the novel (Grant provided Hammond with fractured bone pieces for genetic testing in exchange for his funding), although at the time it was unknown if genetic material could reliably be obtained this way.
In the movie series, as in real life, it appears that the technology has advanced in the past 20-plus years, and InGen/Masrani are now able to retrieve paleo-DNA directly from fossil bones as well as the mosquito-in-amber method.
We just created a Youtube channel segment for our family blog titled “Southern4Perspective” Here is our first video post! Our version of the Mosquito trap. Which is also great for catching flies and wasps.
Modern technology has brought us many benefits, including mosquito traps that cost hundreds of dollars, but sometimes we overlook simple solutions to difficult challenges such as mosquito control. When it comes to controlling pests, research tends to focus on chemicals or concepts that can be patented. Unless someone can make a profit from an idea, the public may never become aware of it.
HOMEMADE MOSQUITO TRAP.
200 ml water 50 grams of brown sugar 1 gram of yeast 2-liter plastic bottle
Or US conversion: 1 cup of water ¼ cup of brown sugar
HOW: 1. Cut the plastic bottle in half. 2. Mix brown sugar with hot water. Let cool. When cold, pour in the bottom half of the bottle. 3. Add the yeast. No need to mix. It creates carbon dioxide, which attracts mosquitoes. 4. Place the funnel part, upside down, into the other half of the bottle, taping them together if desired. 5. Wrap the bottle with something black, leaving the top uncovered, and place it outside in an area away from your normal gathering area. (Mosquitoes are also drawn to the color black.)
Change the solution every 2 weeks for continuous control.
Materials: 2 liter bottle glue 1 tsp yeast ½ cup sugar lukewarm water
Instructions: Cut the top off a 2 liter bottle. Invert the cone and place it inside the straight part of the bottle. Glue the two pieces together. Add 1 tsp yeast and ½ cup sugar to some luke warm water, and pour the mixture into the bottle. Mosquitoes are attracted to the carbon dioxide that you exhale. The yeast feeds off the sugar and emits the same gas, so the mosquito enters the bottle, thinking it will find food there and is trapped.
If you give a man two minutes, he can urinate safely, effectively, and in a satisfying manner. He can do this anywhere on Earth. In any situation. Lost in the woods? Not an issue. On a boat? Simple. Trapped in an alley? Couldn’t be easier. Any situation that would rightly cause the average woman to fear exposure to tetanus, hobo residue, mosquitoes, bear traps, poison ivy, broken crack pipes, slippery ship decks, and 100 other concerns that could send someone squatting with their pants around their ankles panicking into the night are of no concern to a man who can whip it out and not just pee but write his damn name on a wall with it.
