Hawk rodenticide ready-to-use Place Pacs have been an industry standard for many years, combining proven palatability and rodent acceptance with a formula that can kill rats and mice after a single feeding. Hawk baits are made with the active ingredient bromadiolone, a second-generation anticoagulant. Hawk rodenticide Place Pacs are excellent for everyday use in and around agricultural buildings and man-made agricultural structures, with proven palatability in a formula preferred by pest control professionals and ag producers. Use Hawk Place Pacs in a rotational program for up to 6 months, especially for regular maintenance baiting during spring and summer. Hawk Place Pacs contain 1.5 oz of pelleted bait in pre-measured, ready-to-use Pacs. Place Pacs keep pellets fresh and free from contamination until rodents open the pacs with their gnawing and are excellent for tight spaces and hard to reach areas.
