The spring is right around the corner, In order to facilitate your work, I share you my experience.
Years back, when we deployed the "mosquito repelling lights" it was in our wish list that there was USB LED strip on the market. such as:

Things have changed for you benefit, though they are about 2m long. you only need a very small portion of it.
Please put yourselves at the eye of the insects, they try to avoid seeing it (them), put them in the situation, fleeing from one will lead them into the direction to come to the other.. It is better when the strip is cut up 2,3,4 LED per sections to be put at different corner of the place rather then a single one.
BTW: They don't need to be synchronized. - If you need me to re-post the code then drop us a line.
Happy Mosquito Free!Phi
