________ are the most widely used formulation for cockroach control.

Baits are the most widely used formulation for cockroach control due to their effectiveness in attracting and eliminating cockroaches. This method involves using a substance that contains an insecticide mixed with a food attractant, which lures the cockroaches to consume it. Since cockroaches are social insects, they often share food sources; this behavior allows baits to eliminate not only the individuals that consume the bait but also others in the colony when they return to the nest and share the bait's remnants.

The convenience of baits is also a factor in their widespread use. They can be placed in various locations throughout a home or facility where cockroaches are often seen, allowing for targeted treatment without the need for extensive preparation or cleanup associated with other methods. This targeted approach makes baits not only effective but also a user-friendly option for homeowners and pest control professionals alike.

In contrast, sprays, granules, and foggers have limitations. Sprays require direct application to the cockroaches and usually need more frequent reapplication. Granules need to be disturbed (by the insect) to be effective and may not be as enticing as baits. Foggers can provide broad coverage but do not specifically target cockroaches as effectively as baits
