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.

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.

Carbonated water has carbonic acid and too low of a ph for yeast to grow. Tap water can have chlorine or chloramine and take a few minutes (chlorine) to a few hours (chloramine) of boiling or days of sitting out to remove. If you don’t smell chlorine in your water you probably have chloramine. Best to use bottled water.

Also bugs can feed every few days to a week so you can have bite-free nights but still have them around.

Ok if you want to get rid of bedbugs this is what you need to do. Show your doctor the bites on your body and ask him/her to prescribe you a medication called Permethrin Cream, 5%. This is a poison so read up on it before you use it. Do not let your kids use it and follow the directions carefully. I didn't use it on my face, just on the places I had been bitten, on my legs from knees down to feet and arms. This attracts the bedbugs and they will come out and bite you. Once they bite you they will go back to the female and sterilize her and her eggs. Every male that mates with her gets sterilized. When her eggs hatch the babies are sterile and they sterilize bedbugs they mate with and so on. It will wipe a nest out. You can use the Permethrin Cream, 5% once every 14 days and leave it on for 10 to 14 hours. If there are 2 of you, switch off in different times of use. Wash it off vigorously and don't get it in your mouth or around cats. Good luck and have fun. They run after this stuff like it was crack. Remember to do your research on this stuff before using please.

Bad advice. Bedbugs are resistant to pyrethroids (compounds ending with “thrin”. Your confusing permethrin with insect growth regulator that used topically in flea medications such as Frontline plus (methoprene + fipronil insececticide). Experimental use of topical fipronil on humans has been studied but isn’t recommended. Gentrol disks are the recommended IGR solution.

Question 2 months ago on Step 4

About a year and a half ago, i went to an airbnb for my birthday with friends. cabin in big bear lake. the place was old as usual cabins are up there. in the morning i woke up with an insane amount of bites on my legs, but i never thought in a million years it would be bed bugs. figured it was mosquitoes… my boyfriend and i returned to his house after the trip and about a week later i noticed the same bites but not being outside long enough to get bit by mosquitoes. i was getting worried still didn’t think of bed bugs. it wasn’t until one time i felt something crawling on me and i was able to see, it was a bed bug.i ended up bringing them back to my place as well not knowing i brought them back and it was hell. my boyfriend moved out of the place he was at, and got a new bed so his problem was solved where as i didn’t know what to do. so i ended up buying a new mattress. mind you this was already september 2020. after buying the new mattress i didn’t gets my bites. i thought i finally got rid of them. i was wrong. in march i started to get bites again and i didn’t want to believe the nightmare… until i saw them physically and knew i had to figure something out. i read they can go dormant and without food for up to a year. not likely i brought them back from somewhere else again. they had been hiding. so at this point i’ve done alcohol with peppermint, have bought a spray that works well, but i can’t find where they’re coming from. i thoroughly clean my house and room once a week so it’s not that it’s a dirty place. i’ve sprayed everything , took the clothes out of my drawers and closet and te washed everything. i decided to spray DE around the perimeter of my room, where the baseboards are. they finally went away. so i thought. just last night i got bit and saw another one crawling. i am mentally exhausted from this, it’s truly been traumatizing and i i can’t sleep right knowing these things are around me. anyone else have any suggestions?

You have to shield your bed so they cannot feed off you (or anything other living creature in your dwelling). There are several ways, all of them pretty effective. Putting the feet of your bed in sturdy bowls that trap/poison them (like upside down dog bowls.. hard to explain here, but the bugs get trapped and cant climb out or up to your bed). Also using plastic to completely cover the box spring so they can't get above to feed off you. You can google all this stuff. Treat your bed as ground zero. Do every single thing you can to keep them off your bed, and eventually they will die off and or move on. Always make sure you have no bugs on you when when you sleep in your bed. All it takes is one. You can do this, but you're going to have to double down on the work now. Just keep them from feeding and the rest is cake. I would still trap them away from the bed. If they can't get to you on the bed, they will go where the c02 is. Might as well kill them in traps, rather than wait for them to go away or die off. Also, the golden rule is treat your bed like a sterile environment. Don't sit on it, rest on it... anything without making sure there are no bugs on you. It only takes one. You need to google all this stuff, because I can't explain it all to you sufficiently in this comment. Remember: 90%+ of the time, there is a nest on your best somewhere or near it. There are methods to find out what direction they come from. A musty smell is a dead giveaway (once you smell it, you won't ever forget off). If you want to smell the musty smell, capture on in a small bottle and smell the bottle after you shake it around a bit. The bedbug will give off an alarm scent. It's nasty!

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?
