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.

    2 or 3 liter bottle
    Roll of Paper Towels
    Scissors with a sharp point or include a knife or razor
<p>Around September 2009 we got an bed bug infestation and we never knew from where. I'm one of those that those bugs just love to bite... Anyways around this time bed bugs were all the rage on the local news and they were saying that bed bugs where the new human flea. I thought about how we treated a flea infestation with shots of the program (lufenuron) back in 2002. It slowly got rid of the fleas and they never returned. I thought about giving the cats the program because one of the cats had almost pulled all of it hair out because it suffered so much from the bed bug bites. Like the fleas the bed bug population slowly disappeared until there was no more bed bugs.</p><p>Recently I noticed odd little bites on my arms and then got the program again but I have no cats to feed the program to I'm not sure what I should do. I've read that ingesting the program is not an option because it can cause internal issues as well as it remains in the tissues of whomever takes it (pets are normally dosed once a month for 6 months). I've thought of baiting bug dirt or even dropping a liquefied form of the program in a pill bottle of recently captured bed bugs and letting them loose to infect their friends.</p><p>Any suggestions?</p>
<p>This actually works! Best night's sleep in weeks, and no new bites today, I could hug you manicmonday, you are my new hero!</p>
<p>I seem to picked up these nasty little visitors, my guess is from a grotty travelodge while I was on a business trip a few months back. I've tried everything but they are persistent little beggars. I've just made 2 of your traps, so let's see! I'll update tomorrow if I caught any.</p>
<p>Here's a thought. Instead of getting bottled water, why not use a carbonated beverage. That way you're buying your trap and solution in one fell swoop. If it's non-diet, it will already have sugar in it, so all you need to add is yeast. Although you may have to experiment to see if you need to add more sugar. However, it's pretty easy to tell when you have activated your yeast. I'd probably go for a clear liquid, like lemon-lime.<br><br>If you think the flavoring will be a problem, then just use plain soda water plus sugar.</p><p>Thoughts?</p>
<p>Or Seltzer water instead of club soda if you want to make sure there are no minerals.</p>
<p>Although I'm not sure what warming up the seltzer or soda water will do. You do need somewhat warm water to start the yeast.<br><br>I found a bread recipe that uses 1/2 water and 1/2 seltzer along with yeast. It supposedly cuts down on the amount of gluten, but I'm not sure how.<br><br>Anyway, the idea is since you are already using a soda bottle why not get a liquid that already gives off its own carbonation.</p>
<p>We have had bedbugs for the last 5 years or more. We have tried everything even professional exterminators and all the latest treatments. We have covered our furniture, mattresses etc. I am retired and I stay up half the night looking for the bugs. I use clear tape to capture them so as not to bloody up the bed linens. I know exactly where to look for them and every night they are there. The worst place is above my wife's pillow, I would catch 30-40 bugs between 4 and 5am every night. I would catch maybe 10-15 over the rest of the room. About 3 days ago my wife found the trap online and we tried it the other night. There was only one bug above my wife's pillow and only three in the room!!! Maybe because I knew the hotspots and strategically placed the traps. There was about 30 in the trap near my wife's pillow and about 7 in all the other cups. We have tried to no avail, to find the nest near her pillow. We have been living with these bugs for so long I am about to go nuts, I literally scream sometimes. I'll use anything I can to rid us of them and this trap works the best so far. The hardest part was for me to remember to get the yeast when I went to the store.</p>
<p>I recently had bed bugs I tried sprays, bombs, and traps but still had bugs. What really worked for me was dichotomous earth, make sure it is &quot;food grade&quot; DE, so that it is safe around people and pets. I found instructions for blowing the DE powder around my apartment on the web. I covered my carpet, my mattress, put in in dresser drawers, under the bed and the recliner, and on the recliner. It is a little messy with the powder all over stuff but it works. I also got furniture bags, mattress covers for the bed and box spring and recliner, even my office chair. I also washed all my bedding and clothing and stored most everything in sealable bags and/or plastic containers. It was a lot of work and took about a 4 to 6 weeks before I was sure that they were gone. When you use the Dichotomous Earth powder wear one of those round white breathing masks and latex gloves. The powder is very fine and probably not good to breath a bunch of it, it also dries out skin. How it works is that it dries out the bugs in a day or two after they come into contact with it. It completely dehydrates them and kills them. I put the powder down about 3 or 4 times just in case there were any eggs that hatched. Hope this helps, I know it feels like hell going through getting the bed bugs then trying to get rid of them. God Bless.</p>
Bed bugs are too small to see
They are tan colored when first hatched &amp; very small but you can see them. When they've eaten, they have a dark spot in the middle. You can even see the eggs, but they are very small. A grown bed bug is actually quite large, maybe an eighth of an inch &amp; dark red. They are about the size of an ant but leaf-shaped &amp; thicker.
<p>That's what I thought too, until I caught one under my shirt. It was very easy to see crawling around on my skin. They're not that small.</p>
<p>No, any bedbug that has fed is quite visible. The eggs are visible to the naked eye of anyone with good sight. The nymphs who haven't fed can be hard to see, but are by no means &quot;too small&quot; Nymphs who have just fed have an appearance similar to a red mite. </p>
im trying this.. we live in a 120 square meter appartmen made with wood floors... we are tired of this annoying little f**** biting our little baby... if we catch some tonight i promise i will upload pictures.... someone told us to use an electric heater infront of the area were we know they are hiding to kill them with extreme heat: can someone provide feed back about this kind of complementary solution? is there a way to use fire safely to burn them out? do you think that regular big spray cam also help? (we are using Ortho) thanks for this amazing guide... Greetings from Mexico City!!!!
Yes, extreme heat &amp; cold kill them, but it's very hard to do unless you're a professional. Line the room with diatomaceous earth. It's a bedbug insecticide. You can set off bedbug bombs available at Lowe's or Walmart, and spray cracks and corners with ammonia. It kills the bugs on contact, and makes them run from the area. Also, wash the crib sheets &amp; blankets and pillows and spray the crib or bed with ammonia &amp; vacuum frequently!! That's how we killed them.
<p>Be careful with your baby and insecticides please. Do not use fire in the house. Since you are in an apartment, other tenants probably have the same problem and your building is infested. This is common. If you move you would have to leave all furniture and disinfect your clothing and all other cloth bedding, sheets pillows, etc.</p>
have you tested your idea somewhere,where BEDBUGS are?????
Yes, I have caught bed bugs in this trap.
It is very effective.
please let me know,
<p>Is it important that <br>the bottle is 2 or 3 liters? I used 1,5 L but I didn&rsquo;t caught any and they are <br>still biting me.</p>
I used 20 oz. bottles but less of the mixture. We placed them on all four sides of the bed &amp; couches. By morning, each trap had caught at least one baby. We killed all the bugs using ammonia diluted with water. It was just the eggs we worried about hatching &amp; causing a new infestation.
This really works. We were terrified the bed bugs would follow us to our new home. We killed all adults &amp; newborn bugs, but there were still eggs. We placed the traps by the bed posts &amp; couch legs where the eggs were &amp; by morning, our trap had two babies in it. We used several 20 ounce bottles &amp; less ingredients. It worked great. Thanks for the tip!!
<p>Still need to get some yeast, but we will see what happens. </p>
<p>I have a question: I thought that you have to have a bag over the top of the trap because CO2 is lighter than air and will evaporate too fast and therefore will not attract them..Is this true? </p>
<p>CO2 is heavier than air. The Carbon atom makes it so.</p>
<p>trying it :/</p>
They are called fruit flies
<p>I catched one floating in the brew today. Great success!</p>
<p>I actually just made this today. I used a faygo bottle instead; its one liter not as big as the regular soda bottle so I could fit it in places and then I just cut the &quot;recipe in half&quot;, but anyway I placed it next to my sofa where I usually see them and in one hour I had already found three bed bugs floating in the solution! I could not be happier for how cheap and easy this trap is! Thank you so much (:</p>
<p>I tried this trap for mosquitoes last summer. Unfortunately it didn't work very well. I have heard about carbon dioxide traps being effective for bed bug infestations. If anyone gives this a try I would love to hear about the results.</p>
Addendum: After a week or two if you want to continue using the trap you will have to replace the bait. You will need to remove the top and then roll back the paper towel. Then pour out the old liquid and replace it with new. <br>
They fall into the liquid in the bottom. They can be seen, but would be hard to take a picture of.
Interesting. Maybe you could add a photo of the result (the trapped bed bugs).
