I find the best bait for the common housefly (Musca domestica) is rotting meat or carrion, like a dead mouse. Sweet sugary things like honey, jam etc only tend to attract fruit flies and wasps.

ahh yea, It is missing a small step. You must pierce the cap of the bottle a little. A small drill bit about the size of pea or just smaller would be good.

this is a little confusing, if u turned the bottle top upside down and tape it closed, how does the fly get in? Did u cut a hole in the cap or something? Am I wrong or is there a step missing here?

I have a question. What if you mix eveything for bees, wasp and flys. It will be like a bug ore gi. My idea is mix honey, oranges, milk and pheromone will it work? I will give it a try and get back to everyone. If i can get one of each imagine the possiblities.

Just use a 2 liter bottle. Cut the top off, the flip it and insert it into the bottom. No tape needed.

Hello - can someone tell me what 'slow' tape is? and why is it needed? sorry if this is really basic! Thank you in advance but I'm desperate...the number of flies!!!!
I think, it is selotape. Simply you can stick sth to sth.
slowtape, cello tape, cellophane tape, cellophene tape..
scotchtape (US), sellotape(UK).. whiskeytape(Irish).. winetape(France).. saketape(Japan)... slowtape(rest of the world)

duct tape.. duck tape.. gorilla tape..
hany.. honey.. hunny..

it's all sounds the same..

We had a batch of flies hatch and were overrun with them throughout the entire house one morning... yuck. I went looking for a fly strip recipe and came upon this. I knew about it but had forgotten it. My cousin had one set out and it got so full... she never dumped it...again yuck. I made some of these and hung them with string on all the windows where they like to congregate... like someone said they 'go toward the light' :) I use anything sweet like flavored coffee syrup, chocolate syrup, honey, beer. The clearer liquids let you see them drowning better... am I cruel or what? :) I don't know if they get back out because I don't sit there and watch them, but it does clear them out of the house without having to play the game of 'swat the flies'. Actually it is great aerobic exercise if you do it really fast... gets me into a sweat really fast :) That's the up side of it.
does this catch bigger flies or just fruit flies?

Are you sure it cannot come out mate? I'm wondering
As others have mentioned, YES, the flies CAN fly out the opening at the bottom of the "funnel" in the center of the bottle, BUT... IT IS HIGHLY UNLIKElY due to the fact that flies fly "to the light" and thus to the outside walls of the bottle, and do not "FIND" the relatively small opening in the center of the bottle. Again, they "can" fly out, but more than 90% of the time they DO NOT find the ouly opening, and ths, DO NOT fly out of the bottle.
they cant.............................................................................most the time

so you just drill a hole in the cap ??
lazykatana comp7 years ago
You can just take off the cap entirely. I believe that works just fine.

I tried this with peanut butter and it didn't catch one fly. What do you use for fly bait?
Valva used honey (hany). My flies are extremely attracted to spoiled milk. I put a little water and a few drops of milk and you can't keep them out.

the thing works. the reason the fly came into the trap to feed not to get back out again. the secret to the trap is the liquid thats in it. it looks like valva is using honey, but i have also seen beerused which works really well.

hellow I read your comments and i want too tall you this 1) no im frome israel 2) the fly trap is generally for bees and wasp but for flys it is good too

This design is perfect! Learn this in France when I was camping. I used to catch bees with this thing!

I'm guessing that valva's first language is not English. Still the pictures make it easy to see what he has in mind. Still it would be nice to see a good written translation. This is the fly trap I've been looking for. Sometimes the mind boggles at how simple things can be when you stop trying to make them hard. I'll be taking several of these to the stables this weekend. Thanks for posting it!!

While it is physically possible for them to fly back through the open hole, it is not in their nature to fly to the center of something to get out. They like to fly out to get out. That's why flies fly to the window in your house. If you check the related Instructables, the one by CapnChkn (only has a diagram - no picture) goes into extensive detail about fly mentality.

yes, it cant come out
