Easiest Bed Bug Trap





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 li...

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

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.

I know this feed is kind of old but I am trying this for the first time and I wanted to know how frothy the mixture is supposed to be before you pour it into the trap?

The frothiness of the mix is only an indication of yeast activity. That is all that matters.

ok so we don't have yeast, so i put 2 pieces of bread would that work? also is this working for you guys?

Unfortunately, when bread is cooked the yeast is killed. So adding bread probably won't be effective.

we have a house next door that is condemmed, for quite a few years, could they have come from there, since its vacant ? also the house is run down, the roof is really bad shape, and we have gotten mice, also we keep getting head lice, we do have dogs that go out to use the facilities, lol jk they use the yard, im thinking pests have used the dogs to get in our house, or the bedroom closest to that house has a whole in the window, so i thought maybe the bed bugs crawld in through the window. most of us in the house doesn't really go anywhere, my mom works, and we just go to doctors, so idk but the only thing that makes possible sense is that house infested, if so wouldn't the city have to address that?


I found out I had bed bugs 3 days ago. I think I had been getting bit for maybe 1 week. Since Wednesday I have been spraying alcohol and vinegar mix along walls, carpet, furniture everywhere 3x a day. I found them on Wednesday along the seam of my mattress. I only saw two. A dark one a slightly white one with a little red in the middle. I didn’t look anymore after those two. I immediately threw out my mattress and box spring. I live out in the country so it’s on the burn pile. Think they will come from the burn pile back into my house ? I’ve only had one bite since the spraying, vaccuming, cleaning, and putting baby oil in lids set under my child’s crib and the futon I’m sleeping on. The one bite happened the night of Wednesday after getting rid of the mattress. I haven’t seen any sign of them since then. I was the only one getting bit. I’ve ordered spray and DE. Can anyone tell me what they think of what kind of infestation I have? Does it sound light? Is it possible the nest/infestation was contained to my bed? I need some assurance, honesty, something to tell me that maybe I was lucky enough to not have a huge fight against these monsters and that maybe my battle can be short lived

My boyfriend had an infestation when I moved in, in January. I used these traps and diatomaceous earth. Now just waiting to see if anymore hatch. No bites or signs for weeks. Thank you for this!

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

they can live for about a year without feeding, also they will be constantly making more even without feeding, so simply starving them will not work, you have to kill every last one

HEAT: I will say the thing that worked the very first time for us was also the easiest thing we tried. We did one room at a time. We sealed any door and window cracks so the room was sealed and then used a large kerosene, torpedo type heater people normally use in their garages.We put a thermometer in the room and heated it to around 140-145° for 45 min. We did this in each room that was effected. We were lucky that we caught it early and only 2 of our rooms were effected. We used this method on both rooms and two years later we are still bug free. Before the heat treatment we had tried bombs and sprays to no avail. Of course we still did all laundry in effected rooms on high heat and daily vacuuming during issue but the heat was so simple and worked completely. I was impressed after trying so many things.

Hello. Where did you find this type of heater? I have a close friend in need of this help. Thx in advance

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.

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.

They cannot survive prolonged heat or extreme cold. So, depending on where you live, it's climate and season, you can either kill them off with heat or cold. Do some research. If you do use extreme cold, make sure you drain your water pipes, water meter, if you have one, thoroughly or they will burst.

It should be noted that the adult bed bug can hibernate without feeding for up to three years so starving them out in four months isn't possible.

The traps will be useful for those hibernating in your storage, however, as they mimic live breath.

Hit up tractor supply and buy a couple huge bags of Diatomaceous earth (they have it cheap). cover..well, everything in the house with it. Fighting the damn things myself right now and while it isn't instant-kill they definitely don't like going through it. And it's not a chemical, it's a mechanical assault so they have no immunity. Isopropyl alcohol is good at killing the bugs and the eggs on contact but frankly i just have them in a 10x10 foot room and i've gone through almost a gallon in the past week. Heat works too, if you bring your items to 140 degrees for 20 minutes or so it's lights out. It also doesn't hurt to experiment and see what's actually effective chemical-wise since different bugs are resistant to different things. The Hot Shot stuff seems to just make mine hungrier. I've also got some sprays and such from Harris (they make a kit) and it seems to be working (came with the diatomaceous earth), using the 3 part kit in conjunction with alcohol and ecologic bed bug killer (that appears to just be diluted lemongrass oil but damn that stuff seems to work).

I'm thinking about building one of these traps and surrounding with the DE

I know this is off the wall I do thank you for this information and I will try it all. I am a single mother with 2 kids and full time job. My baby sitter over the summer advised me she had bed bugs. Well she gave us a gift from....so I noticed bites on myself always feeling like my skin was crawling. Was not my skin! Zig zag bites in the morning I've been kicked out my room for months now.

What if you use tap water? I know you said bottle or filtered but what if that's not an option?

Any water that you can drink and survive will be fine for the yeast.

Our tap water contains chlorine so we must use distilled, bottled or boiled water.

No, yeast will do just fine in any water that you can drink. Unless your municipal water is chlorinated to the level of a swimming pool it's not a problem. Consider that you can make bread using tap water and yeast. I've been making rum and whisky for years with tap water. Granted each water district will be different but there are maximum levels allowed. I doubt there are many places where the chlorine is so strong that you can't make bread.

How long is one mixture good for before you have to make a new one

It’s not about the yeast.
Bedbugs will shy away from the chlorine in regular water. They sense the chemical and will bite you instead.

If you are heating the water there is no problem with using tap water that has chlorine in it. The chlorine boils off while the water is heating. I have known this from years of wine and beer making, so it is not a problem to start with chlorinated tap water. I also do this to prepare tap water to drink when my regular bottled drinking water is not available.
