The Circle of Death. Er... Life.

Our pest control technician applied insecticide inside our building today. We have seen more roaches and beetles than usual this year. (Last year, it was mole crickets.)

What I want to know is, why do they all come inside to die? I'd rather the insect struggle outside and get spotted by a bird, who goes, "Ooh, lunch!" Then, when the bird is convulsing because of the insecticide, it is in turn spotted by a feral cat. The cat eats the bird, and then we have one less cat randomly roaming our campus. (Note, this does not apply to pet owners who very carefully monitor their domestic cats and keep them inside.)
