Close the burrow and monitor weekly. As long as burrow continues to reopen, close the burrow and re-bait station. Close all burrows in cool cells with shovel. Bait stations should be placed next to any burrows which reopen. If there are any holes in ceiling plastic or gnawed holes in boards, place Hombre Mini-Blocks next to holes using wire or nails to secure bait.
Check drop ceiling over egg room for rodent activity.
If rodents, rodent damage or rodent droppings are visible, place Hombre mini-blocks in areas where activity is seen. Remove all interior uneaten bait which birds might reach immediately prior to restocking the house. Once the house has been restocked, place bait only in locations inaccessible to the birds. Next clean out, rotate to Boot Hill Place Packs and follow the same instructions, except use Boot Hill Mini-Blocks to nail up or wire up at roof rat points of entry. The number one mistake is not using enough bait .
