Beating the Bugs
In regard to your article, “Where Have All the Solids Gone?” (Lab Detective, TPO, June 2012), we have had pretty good control of midges using just good old blue-light bug zappers. We hang them in the buildings, over the clarifiers, and even inside our EQ reservoir from the ceiling. The humidity eventually gets to the electronics, but at around $70 apiece they work really well for three to four years. Just replace the lamps and clean out the basket. We had to rig up a 5-gallon bucket under some of the indoor units to hold the remains of the insects.
