With this home built flea catcher I was able to catch 50 fleas in one night. Yes I certainly did count them!

I have seen several other prototypes on the internet, but I wanted to share my experience with my results.

The part list.
Dish Soap
Ground Black Pepper
LED Night Light
Container Lid
Toaster Over Tray

There are several flea traps on the market. Here is one such example. However they contain a sticky pad that you will need to eventually replace. I am adding this language expressly for the "I Could Make That" Contest. Please vote and share with a friend =)

Step 1:

This part of the experiment verifies that soapy water will work for the trap, but regular water will not. The soap reduces the water surface tension. Basically this trap wants to drown the flea, not let it glide on the surface of the water. Why did I use pepper? It is similar in size and weight of a flea. If the solution is correct and it pulls a small grain of pepper, then it will definitely pull down a flea into the trap.
Thank you for breakingvit down for a grandma can understand the engineering for building. Fleas are such desease carriers; you may have saved humanity. I pray you win!

I never had a problem with fleas until my home girl brought her dog to my house. I noticed I was getting bit around my ankles. But I have one question do I have to use a night light over the trap
New step: don't invite your rachet friends over. Only joking.<br><br>Yes, you must use a night light. They are not attracted to heat, but they will jump towards the light. Good luck.
I did this and it works. I make the water green with the detergent and in three days I've killed at least 40 flees. So much relief from the ankle biters.
Makes me smile everytime I read someone's story. So glad it worked. Enjoy your weekend.
<p>I'm surprised but this isn't working for me. I've done all the steps, the pepper sinks, I know my dogs and cat have fleas. I've seen them on me and them.</p><p>Its been a few weeks and I'm cleaning, shampooing, using diatomacious earth, the traps catch nothing and the cycle starts again, frustrating! I am getting Comfortis for the pets but I need to kill the ones in the house. I'm doing it just like instructed.</p>
Great comment. Be sure it is the only light source in the room. Small detail but very important. Thanks.
<p>Rusty - Make sure the night light is the only light source in the room.</p>
Very interesting. You are the first person to say this. Sounds like you really cleaned your house and pets. Make sure to put the trap near an area that the pets frequent or in a central area of the house.
<p>Hey there!!! Great read!! I have become rather desperate and I am soooo tired of being the delicacy of the fleas that have gained control of my home. I've never had such a problem before and then my son and his girlfriend's sweetie pie had pups and they were infested and then they bring all five pups and the Mom over for me to bathe and now I can't get rid of them. Tried your trap lastnight in my room and it worked!!!! Now for the rest of the house :) Yaaaaaaaay!!!!</p>
Great job! I love reading these updates. Always makes my day :)
Wow! This really is working so far. I put out 2 traps and after 3 hours, I've caught about 20 fleas in each trap. Also, I'm putting food-grade diatomaceous earth on my hardwood floors and rugs and vacuuming every day. I've got both dogs on Sentinel now too. However, I'm wondering now if anyone can suggest methods I can use to make myself less appealing to the little suckers???
Every time some one writes a comment it makes me smile. I strongly suggest non toxic or natural methods.
This most certainly worked for me!! We have all 3 of our fur babies on oral treatment but we still get infested with fleas from time to time. I used dawn dish detergent, a rimmed plate, warn water and a tea light! Within five minutes I had about 10 fleas trapped!
Excellent results! Thank you for sharing!
<p>Where's my comment? I'm not gonna rewrite all that!</p>
I feel sorry for your cat. I am allergic to them and learned to adapt any flea-abatement approach to the fleas' reproductive cycle; after a few weeks, all of them are long dead - including the eggs. <br> <br>To those who think the pepper is part of the solution, I am pretty sure that the pepper was only used in this case to test the solution for it's ability to drown the fleas - not to pepper-spray them. <br> <br>I once moved into an apartment, unaware that was it was wholly infested, waking up the first (and last) night there with all kinds of swollen bites around my ankles. My pair of poor indoor cats, who had never even seen a flea before) were even more miserable than my GF and I. I decided from that point forward to try out potential rental properties by first planting flea 'traps' with night lights over a cup of water with rubbing alcohol and a drop of dish soap added as a surfactant - the alcohol makes the soap more effective. I used a piece of white card stock bent like a half-funnel with open front to act as a catch-all backstop/sliding board so the over-energetic fleas who jumped too hard towards the light would hit the backstop and bounce/fall down into the cup 'o death.
Thanks for the comment. I do state in my instructables steps that the pepper is to test the water tension. If the pepper sinks in the solution, so will a flea.
<p>actually that was not really clear but kind of becomes clear as I read through all of the steps. </p>
<p>Does anyone know if fleas are always visible? I mean, are they super tiny when they first hatch? I don't have pets but I keep inheriting fleas left from prior tenants. The first time I got rid of them by spraying eucalyptus oil in water around the house several times a week for about 6 wks. I didn't even vacuum often. The second residence has been more challenging. The eucalyptus oil has not seemed to help, even spraying it on myself doesn't seem to deter them from jumping on me. I read about this trap online and set it up but not one flea fell for it, however there were several around at the time--I would see 5 to 10 on my legs throughout the day. I would catch them and throw them in the liquid and they did drown. But why aren't they attracted to the light? I know they are attracted to vibration (as well as warmth), but are there a certain species that is only attracted by vibration? I hate killing anything and thus the eucalyptus, which only deters them not kills them and they eventually leave. But once I read they can carry disease I had to give in. Now I'm using baking soda on the carpets, dries them out and kills them, and vacuuming every other day. They have greatly diminished. But I often feel them biting me still, yet now I can't see them. Is it possible they are newly hatched and too small to see? Does anyone actually know they answer to this (cuz no one wants to read a bunch of guessing--we can all guess pretty good ourselves). Thank!</p>
<p>I tried this out and I'm not sure if I caught a flea or something else. Any idea what this could be?</p>
<p>looks like crushed pieces of a dead bug that probably fell off someone's shoe. Definitely not fleas. </p>
A bit of preventative maintenance. Put 1tsp apple cider vinegar to 1 qt in your pets drinking water. Takes a couple weeks to start working. But the theory is that the vinegar with become present in their skin and hair folicles. Still waiting for results.
<p>what does the vinegar do?</p>
<p>If you have cats do not use vineager in the water as it can cause liver damage and kidney failure in cats</p>
Keep me posted. Sounds bizarre and interesting.
<p>Out side I used cooking oil and a tea light, killed a lot on a cookie sheet, had an infestation in the yard. Just put tea light on a brick or rock.</p>
Very neat outside trick. Never thought of this technique outside.
<p>Nice! Dish soap is a great pet shampoo for fleas too. Not a lot of people realize that. I like to use Dawn on my dog. Works great. Safe for kittens and puppies too.</p>
Thanks for the great tip
<p>I made this just 10 minutes ago and put out in my garage. Walked out 5 minutes afterwards and about 20 fleas were there in the trap. I didnt think that they were that bad out there. This worked like a charm! Thank you for posting this</p>
I am so glad it worked so fast
GENIUS idea - Thanks for the Help, my dog ​​makes me mad otherwise
<p>Front line works great</p>
Thanks for the comment. I will gladly take your compliment.
I just use soap and water and squeeze a lot of soap into the water. It has worked perfect so far!
<p>great to hear it.</p>
A glass pie pan works great too. I used a clamp-lamp with a 60 watt bulb. The warmth attracts them towards the lamp and when they jump towards it, they fall into the soap with the same results.
Thanks for the comment. There are interesting facts roaming the internet as to whether it is the light or the warmth. But since LED light is more eco friendly and uses less power I decided to not use a 60 watt classic incandescent bulb.
I won't argue with success! All I know is, they managed to find my leg and my dogs in the dark. :-( What an awful few weeks that was! This solution definitely worked better than the expensive commercial products!
We have had problems with fleas on many occasions, but no more. I bought a steam cleaner and steamed every floor in the house twice a day for 2 weeks, then about once a month. We have had no sign of fleas now for over 2 years
Thanks for the comment. If you have a cat that goes inside and outside, then having a way to trap new fleas that enter the home is where a trap comes in handy. I am curious if you currently have a pet.
Yes ecoben, I still have cats and my daughters dog on occasion. I steam the carpets and hard floors about once a week now but have seen no sign of fleas since the second week after I began steaming. Almost everyone in our street has cats or dogs so the potential for fleas is still there. I liked the idea of steam as it uses no chemicals and is quick and easy to do. (As a bonus the steamer can clean tiles and the oven).
You sir are a GENIUS. <br>This method uses their own instinct against them. Keep in mind that this will not get the unhatched eggs.
Thanks for the comment. I am aware that it will only get the mature fleas, but those are the ones that bite. =)
Panicked when my son was bitten in the night even though we don't have pets and had read about the water/dish soap/light flea trap. It only takes a few drops of dish soap. I used a desk light, so it is interesting that a night light worked. I didn't use a toaster tray, but that is a nice touch to keep others out of the dish. In the end, I only caught one biting midge, so IMO it was a success! Glad you posted this for others to see.
Thanks for the comment. I am glad that you had success with my instructables. =)
