Jef, in many zoos or botanic gardens are roaches an everlasting problem and (frass)baits (e.g. Maxforce) are the method with the lowest quantity of insecticides, if used with small points at safe places (e.g. bait stations). Additional using sticky traps, to catch roaches outside the areas of the display zones could be an integrated method.
Insecticide dust like boric Acid and all other liquid insecticides could leed to contamination and kill effects on the live insects after contact with the roaches.

The keepers are understandably concerned that not-yet-dead roaches will get into the insect exhibits and bring the insecticide/diotomaceous earth/ boric acid/ et cetera (depending on what I end up using) with them. It is an area with other live animal exhibits, so sources of food and water are abundant, as well as nice warm harborages. I don't think there is an easy answer, but I'd love to hear if anyone else has faced this issue, and what they did. Thanks!
