Had a death in the control (no adhesive) group. Perhaps it was due to the wound that was inflicted upon it during hour 0. Many of the roaches were upside down in the minicups when looked at and even when flipped to their proper orientation they quickly flip themselves back over. The roaches seem to be unable to, or at least have a hard time, to flip themselves over once they are on their backs. Perhaps they are exhausting themselves after trying desperately to flip themselves over that they eventually die?

It was difficult to find ingredients for Treatment H; only that it was heavily touted as being so safe and non-toxic to humans and the environment. The specific concentrations of ingredients or the ingredients in general were difficult to track down in a number of treatment groups due to them being "trade secrets".
