True
Important structural pests that are most likely to develop resistance
Cockroaches, house flies, bed bugs, and fleas
Insecticide rotation is most effective when rotation is made among insecticides with
different modes of action
When resistance occurs, it usually reduces the effectiveness of
all insecticides that have the same MOA (cross resistance)
Borates must be ________ in order to be effective
ingested
Precise mode of action is still unknown
Borates
Carbaryl and propoxur
Carbamates (only remaining carbamates registered for urban pest control)
