Sorry for the long delay guys, I've homework and etc to attend to, but here's the results! ^^

Hypothesis: If a selected, common cockroach barrier can stop a cockroach from passing onto a non-coated glass or acrylic section of the same object, then less cockroaches will escape captivity.

Temperature: 23.9 degrees Celius

Humidity: 40%

Each 6.09600 by 3.04800 dm pane of acrylic/glass was coated 10.2 cm from the top with a 2.5 cm band of the selected substance. Light was relatively dim in the room. Each roach was tapped on the abdomen with a long toothpick and was guided into the direction of the band. No cockroach was used more than once, and each had all 6 of its legs.

Unfortunately I didn't have the resources to test each species, but I used 3 and 4th instar hissers to replicate the weight.

LOL, sorry, can't help myself. So the long and short of it is that nothing is going to contain our little 6-spiny legged buggers. Zephyr, you know I mean this in a big sisterly way ;)
