RODENT GUIDE FOR RAINY SEASONS AND FLOODING

SUMMARY

Rainy seasons and flooding often drive rodents to seek shelter and food indoors, leading to property damage and health risks. Learn effective strategies to safeguard your home or business from rodent infestations during wet conditions using exclusion methods, proper storage, and pest monitoring systems.

FEATURES

• Seal Entry Points: Close cracks, vents, and drain openings to block rodents.
• Elevate Storage: Keep food, feed, and waste off the ground to limit access.
• Use Flood-Resistant Materials: Opt for metal or plastic containers over cardboard.
• Install Drain Guards: Prevent rodents from entering through plumbing and drains.
• Set Monitoring Traps: Track early activity before infestations spread.
• Maintain Clean Perimeters: Remove debris and vegetation near structures.

GUIDE DESCRIPTION

Rodent infestations are more common during rainy seasons and floods as rising water levels drive rats and mice to higher, drier ground—often inside homes, warehouses, and food storage areas. Flooding also displaces natural food sources, forcing rodents to scavenge human spaces for shelter and nutrition. Understanding these behavior shifts is essential for implementing timely prevention measures.

The first line of defense is exclusion. Rodents can squeeze through gaps as small as a quarter inch, so sealing every opening is crucial. Focus on wall cracks, gaps around pipes, and unprotected vents. Using weatherproof sealant, metal mesh, or concrete fillers helps keep them out even in high-moisture environments. Drain guards and covers are particularly important in flood-prone areas since rodents frequently use sewer lines and plumbing as entryways.

Storage practices play a major role in reducing attraction. Food, feed, and waste should be kept at least one foot off the ground in sealed plastic or metal containers. Cardboard boxes can quickly deteriorate in damp conditions, becoming nesting material for rodents. Likewise, ensure that garbage bins have tight-fitting lids and are emptied regularly to minimize scent trails that attract pests.

Maintaining a clean environment around your property also discourages rodents from settling nearby. Remove debris piles, dense vegetation, and standing water, as these create hiding spots and breeding areas. Regular inspections after storms can reveal burrows, droppings, or gnaw marks that signal rodent activity early on. Setting up monitoring traps helps detect problems before they escalate.

During flood recovery, always check crawl spaces, basements, and storage sheds for signs of infestation. If necessary, consult pest management professionals who can assess structural vulnerabilities and apply targeted solutions. By combining prevention, sanitation, and monitoring, you can protect your property from the surge of rodents that often accompanies heavy rain and flooding.
