Screens on windows, crawl spaces, and vents are often damaged in farm and industrial buildings. Check these carefully for needed repair or replacement. One of the greatest challenges in farm buildings is preventing feed and seed from being a food source for rodents. Good sanitation practices are very important. Clean up spilled feed, and store feed and seed in rodent-proof buildings and containers. Keep sacked materials off the floor when possible. Excluding rodents from livestock and poultry operations is another challenge due to livestock and manure management and various animal husbandry practices. Nevertheless, rodent-proofing is important and can be accomplished. Many of the entry points already identified for other types of structures apply to farm buildings. Additional problem areas include insulated walls used for harborage, feed bins, and portable feed bunks.
