I'm sure you can you use the same water for the week. Eventually the water might get dirty, it might evaporate, or the fleas in the water might be gross. Use your best judgement. I have found after the first night most of the fleas for that room have been trapped. But you could keep it going for a few nights to see what happens.
One part of the project was to make a cheap flea trap. This trap only uses a few drops of soap. Using lots of dish soap would create a similar affect, but soap costs more than using water.
Actually you do NEED a light source. The only way this is working for you is if your room is dangerously infested with fleas. Have you ever seen moths going towards a flame?If you had read my instructions I detail that the main reason for this project was to show that the fleas are not going towards the HEAT, but rather are attracted to the LIGHT.

But if you are catching fleas everywhere you may need to thoroughly clean your room. The traps you are using are working from the fleas randomly jumping inside VS using a beacon to get all of them out of your room.
Great work. I love seeing the photo. I would do this for a few nights and put fresh water until you stop catching fleas.
Neat trick. Any light source should work including a candle. Please be careful with an open flame and I wouldn't leave unattended. Also, the research shows that fleas are not attracted to heat, but rather are attracted to the light.
You are correct. There are other studies that show flickering vs steady light. But most people have night lights somewhere in their house and they are easy to buy at the store. The biggest impact is that you don't have to have a heat source, which is the most common myth.
Let us know the results. If you don't actually have pets this should work quite fast.
I would do one room at a time. Rotate each night until you have the done all the rooms and you can also see the results, without having to buy anything extra for each room. Any night light should work great. I prefer LED night lights because they only use pennies of electricity per year.
I do not recommend any chemicals in the home. It is simply not needed and if you do a quick read on the warning label I'm sure it will be enough for you to think twice.
Great question. My guess would be that the radius is the amount of the light that is easily visible in the room. So any standard room would be fine. Think of a light house casting its light into ocean for the faraway ships.
