Final answer:

Step-by-step explanation:
The most widely used formulations for cockroach control include insecticides, traps, baits, and repellents.
Insecticides are substances used to kill or repel insects. These can be applied as sprays, dusts, or granules to target cockroaches. Traps can be used to capture and eliminate cockroaches, either by physically trapping them or by containing a poisonous substance. Baits are also effective in controlling cockroaches as they contain insecticides that are attractive to the pests. Repellents, on the other hand, are substances that deter cockroaches from entering a certain area.
