My experience. One of the Flemmish babies, Cheyenne, stepped in a glue trap in another room and came hopping up to use for help....making a clap, clap, clap sound as she hopped with the glue trap caught on her foot. I picked her up and carried her to the kitchen sink. My wife poured a small amount of vegetable oil on the bunny foot/glue trap interface and the glue trap immediately released. Next we washed Cheyennes foot with dish detergent and water to get ride of the vegetable oil, and then used a hair dryer to dry her foot/bottom leg fur. I kept my hand on her bottom leg to make sure the hair dryer was not too hot.
Also, you buy little traps for the cockroaches to crawl into for poison food, The rabbits won't be able to eat the poison. Also, I don't think insecticide will bother rabbits, but it's best to not expose them to insecticide I'd guess.

Why did we name her Cheyenne? She's a shy rabbit, very reticent to establish social contact. So...Shy Ann, spelled Cheyenne. Her sister rabbit has the opposite personality. The sister is very outgoing, gregarious, socially interactive. Two sister rabbits...very different personalities.
