Introduction: Easiest Bed Bug Trap

About: If your in the USA visit the web site and learn about a better way to pay taxes. It may sound boring to start, but it's really not. It will give you the choice of how/when to pay your taxes, and could lift…

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.

Is there any substitute for the yeast? I just don't have it, it is a long story, but I don't do the shopping or leave the house, so I am stuck with the bugs who only affect me right now, and I will lose my mind shortly, then there will be no one left to fight them...
Why did bed bugs not exist before like 5 years ago? Never in my life, and then 5 years ago....we no longer say "don't let the bed bugs bite", light-heartedly, anyways.

The animals that bed bugs feed on breath in Oxygen and breath out Carbon Dioxide. Bed bugs have learned this so are attracted to the smell of Carbon Dioxide. Yeast feed on sugar and expel Carbon Dioxide. That is the reason they make good bait for these traps. Nothing else that I know of does this.

Bed bugs have always existed, but only recently started getting spread around. People used to repair things. Now they just toss things that don't work to the curb and other people come along and pick those things up. Sometimes those things have bed bugs on them. People are now starting to learn this.

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.

I saw my first ever bedbug on my couch about 5 days ago. Couldn't believe it. Where the heck did the "little darling" come from? So far I've only seen 1 or 2 per day but it still makes me itchy all the time. :) I spread the diatomaceous earth under my couch cushions, on the entire floor area under the couch, and also behind the couch. Haven't seen them any where else.
Yesterday I saw none at all (I was excited) but today at about 3:30 pm I saw ONE on the backrest area of my couch. Quickly sent him to bedbug hea......Hell. Will be making the trap tomorrow. Need to buy yeast and bottled water today.

One website said you should use only "spring" water - true or false? Oh and..add 3 inches of the yeast mixture...really? How much is that when I won't be able to see into the paper towel covered bottle? Do you think molasses is better than sugar?

You can boil tap water. Its asking for filtered water because of the chemicals added. All you are wanting is water yeast and sugar and maybe a slice of bread to feed the yeast. The yeast creates carbon dioxide as it eats. And chemicals in tap water might kill off the yeast. You want the carbon dioxide to attract the bugs.

Here is a very effective weapon in the bedbug arsenal! Fill a spray bottle up with regular rubbing alcohol . Add some eucalyptus oil(Amazon) . Take your bedding off and spray the box spring and mattress. If you see any spray the heck out of 'em. They will die instantly because the their shell is very thin and has no protection against the alcohol. they also hate the smell of eucalyptus. Lavender oil may work as well if you like that scent better. Spray the bedrails as well. Check under the mattress and bed spring as they love these spots. This will penetrate and kill eggs as well. Then buy you some mattress and boxpring bedbug protectors-about $25 a piece on Amazon. They have pillow protectors too about 4 for $10. Do this until you don't see any movement or signs(spots) . Be vigilant for several weeks. Then check every month.

70% alcohol 1.50 at walmart. Didnt know about eucalyptus. Will try it. One tenant has been fighting and that is after shelling out 1200 for extermination

Question 11 months ago on Step 4

Is there any information about the distance around which this is effective? Various units in my apartment building have had to be treated more than once in the last few years, so I don't want to risk attracting critters from other units!

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.
