To start mix your sugar/yeast solution to bait the trap. Bed bugs are attracted to carbon dioxide, and yeast produce it as they feed on sugar.

Mix 2 cups of pure cain granulated sugar to 2 liters warm water. Use bottle or filtered water so to not have chlorine. Add a little yeast. If you buy a packet then use about 25% of it. Otherwise use about 1/2 a teaspoon.

Set that aside. You'll need it at the last step. It should be frothy by then. If not then it won't take long.

Step 1: Start

Bed bugs have become a major issue around our country (USA). I think it's because of our bad economy. People are picking things up from beside the road and carrying it into their houses. Before you do this you should be very careful because those things might hide bed bugs. Once you have them it's very hard to get rid of them. Traps are unlikely to solve your bed bug problem, but if you can't afford to pay expensive exterminators then traps may help.

This is the easiest bed bug trap.

Stuff:
    2 or 3 liter bottle
    Roll of Paper Towels
    Tape
    Scissors with a sharp point or include a knife or razor
    Sugar
    Yeast

Step 2: Prepare the Bottle

Cut the top off along the top edge of the label.

Step 3: Make Footholds

The bed bugs can't climb the smooth plastic bottle, so you have to give them something to grab as they climb. Wrap the bottle with paper towel and tape it on. Make it even at the bottom. Cut off the excess at the top, but leave a little overhang.

Step 4: Grand Finally

Fold the top over into the bottle, then invert the bottle top and insert it into the bottle. It should be even at the top with no plastic sticking up. 

You are done. You can add a little talc powder inside to make it more slippery, but I haven't found that necessary.

Put about 1/4 cup of sugar into the bottle and then about 3 inches of the sugar/yeast solution.

Put excess solution into the fridge. The yeast will go dormant in the cold, but become active again when warmed up.

Place it in a place where you want it to catch bed bugs and it won't get knocked over. You might find bed bugs in it in the morning. If you don't, that doesn't mean there are no bed bugs. They will only come if they are hungry.

There is a flaw in this recipe. It completely lacks nutrients to support healthy yeast growth. Yes, it will work, but it's the equivalent of trying to raise your kids on nothing but popsicles (yes, I've tested this on my kids. The first child was raised on popsicles, the second on microwave hot pockets, and the third was left to forage for itself as a control. Results were compared on measurements of height, weight, and GPA...).

You can easily generate much more CO2 for a longer period of time (7 to 10 days). All you need are yeast vitamins. The easiest thing to do is to simply substitute molasses for sugar. My recipe calls for 250 grams of molasses mixed in 1 Liter of water and baker's yeast. A alternative method is to use 1 Liter of water, 250 grams of sugar, baker's yeast, and 1 slice of whole wheat bread. Simply take a slice of bread and add it to the sugar water solution. Put the mix through a blender until smooth. Add yeast. The solution may be poured into a common 2 Liter soft drink bottle to ferment. This gives the solution adequate headroom to bubble, froth, and expand without spilling out of the bottle. If you put a full 2 Liters of fluid into a 2 Liter bottle then the fluid may spill out as it begins to generate CO2 and foam.

At the end of 10 days or when it stops bubbling you may choose to drink the solution as it will have turned into a sort of beer or wine. It actually tastes quite good. It will contain about 5 to 10% alcohol by volume.

What you are describing is likely the precursor to rum!

Indeed, this is how I make rum. It’s quite easy. The trick was learning that the yeast need nutrients to grow a healthy colony.

How much yeast do you use in your recipe? the same as the original recipe - 1/2 tsp?

The amount of yeast doesn’t much matter. Even a pinch should be enough to get the yeast colony started. More is better only because it ensures that the yeast will overwhelm any other organisms that might also try to start a colony in your nutrient solution. A half teaspoon is fine.

I plan to make my bedbug trap tomorrow...you say it's better to use molasses rather than sugar....and use 1 litre of water + yeast. Just to clarify......it's 1 litre water instead of the 2 litres in the original recipe? And as for yeast, how much? As in the original - 1/2 tsp? And by the way..is this quick yeast?

Yes, 1 Liter of water in a 2 Liter bottle. The amount and type of yeast does not matter much. Quick yeast should work the same as regular yeast for this purpose. The amount of yeast doesn’t matter much either as the yeast reproduces. Half a teaspoon is fine.

I'd believe you if you hadn't said that you tried raising your kids on various things mentioned above. But then you also used more precise measures so now I don't know.

Used in the trap it will have bed bugs in it, so I for one would not care to drink it.

Back once again. I'm so dissappointed. Tried again to make the the liquid "bait" for the "Easy Bedbug Trap" If only it WAS easy. Did everything according to directions but the liquid only foamed a little. Water was a little over 100 F and under 110 F, but the amount of "bubbling" was pretty minimal. Am I expecting to much? I doubt it would give any CO2. Does it have to be "proofed" in a specific type of container....should it be covered? Can't decide what I'm doing wrong. Frustrating!! Haven't seen any of the critters for a whole day.....but they've fooled me before. Don't want to get my hopes up. I was so counting on the trap to lure some of them to their death. But what if there was 50 in the trap....or 5 only... would that really tell me anything? If it was 50 that could mean I killed most of them, or that I have 100's and only 50 showed up. Same with 5 bugs. Do I have very few, so 5 is a lot, or do I have 100's and only 5 took the bait? Ahhhh!

Back again. Made up the trap "BAIT" yesterday and it didn't foam at all. Then I realized I had bought instant fast yeast and carbonated water. I suspect one or both them caused the failure. Or water may have been slightly too hot - need to leave thermometer in longer.Trying again tomorrow with regular yeast and non-carbonated water. Good thing it's all so cheap. Recipe says 1/2 tsp yeast yet another says to use whole package. Can you use too much? Didn't see any bugs today but they're just messing with me...:)....making me think they're gone. Didn't see any all day yesterday...then at 10:30 pm saw 3 together. Think I'm seeing a few tiny ones now. With all the Diot? dirt not sure how they get to me. It's under cushions, on floor under couch, lower back of couch and at the very top of back of couch To lay on the couch I "cacoon'" myself in a blanket so there is no flesh showing. But I have no bites..guess I'm not allergic...if they haven't bitten me they would be starving.

I was going to say that the recipe doesn't say how much water to put into the 2 ltr bottle but then I realized it does....indirectly, when it says to.....add "3 inches" of the sugar/yeast solution - which is actually a water/sugar/yeast solution. How much that is, is unclear, and hard to estimate when the bottle is wrapped in paper towel. May be better to put 3 inches of water in a separate 2 litre bottle and measure how much it is. And does it have to be 3 inches.....can it be 4 inches? I was going to do it and then post it here but right now I can't seem to locate a ruler or a measuring tape.

I'm Going to do this today. I've been sleeping outside on an air mattress in my gazebo for months now. They should be starving by now.

I got infested from a sofa i bought at a thrift store. Never again. We pulled the beds apart and sprayed and used DE. Still got bitten.

I've started boxing everything up and ripping out old carpets and under pads; the old wallpaper is next and the paneling. House is old ( built ca. 1947) and absolutely FULL of cracks. I keep praying State Farm covers bed bug infestation disaster clean up, but they won't. Ugh.

I wonder if i can use small bottles of it to put in the boxes of stuff. The boxes are plastic and probably slippery for them to climb out of ... I've had these bugs for going on a year now ... At my wits end

You can put anything that you suspect have bed bugs in clear sealed bags in the hot sun all day maybe 2 days and the heat will kill them. Can be non-clear also.

I can completely relate to your situation. My family have been battering this nightmare for over a year as well. I have tried everything except an exterminator, which I should have done right away because I've spent so much money on traps, sprays, DE, steamer, etc. As soon as I think we have won the battle, it starts all over again. You never know exactly where those little eggs are! We have gotten to the point of carefully washing and spraying everything, packing it up, buying new bedroom furniture and moving. As vicious as these things are, I hope that I haven't missed that "one little egg" that could possibly come with us.

The types of heaters that GretchenF3 is referring to can be found at places like The Home Depot, Lowe's, and Walmart. (I wouldn't suggest checking your local thrift store for one, heh heh!). I love her idea about using the heater in each room, it's a heck of a lot less expensive than hiring an exterminator who uses basically the same method, only all in one day. I would be afraid that precious family treasures (like photographs) would be destroyed during a heat extermination process. At least if I use Gretchen's method of heat treatment I can make sure certain items are safe when the room they're in is being treated!

Thanks Gretchen!!

See my post above. Take a 1 week vacation and kill them off with prolonged high heat or extreme cold.

Bedbugs can survive cold environment. bedbugs survived lower temperatures, with eggs surviving in short-term exposures … to temperatures as low as -25° C,” the researchers write. But the bugs are not freeze tolerant, the scientists found, and they can be killed — no matter their stage of life or feeding status. All it takes is 80 hours in temperatures of -16° C.

I mean, you prably didn't have to destroy your carpets (unless they were ugly as hell then sure). You could just buy a heat gun or a good hand held steamer and steamed every last bit of the carpet. Same goes for clothes.
