Shreveport Rodent Control: LSU-Backed Trapping, Sealing and Licensing Basics

What to look for

LSU AgCenter's rodent guide treats three species together because Louisiana homes see all three. Norway rats are heavy burrowers that live along foundations, under slabs, near water and around garbage. Roof rats are climbers that use trees, fences and utility lines to get into attics. House mice live inside, in walls, cabinets and appliances, and they carry the same diseases as rats. Shreveport's climate gives them every advantage. Summers average around 94F, humidity sits near 73 percent and about 51 inches of rain falls each year, so food, water and cover are everywhere. Winter lows around 37F are mild enough that outdoor populations survive, and as fall nights cool, rodents push into homes for warmth and shelter. The Red River and the creeks and drainage that feed it give Norway rats water and soft banks for burrows. Roof rats, the usual attic rat along the Gulf Coast, also settle into Shreveport rooflines. Mice do not travel far from their nests, LSU notes, which is why trap placement has to be dense to work.

Mice in appliances: what LSU AgCenter warns Shreveport households about.

Chewed insulation on cords is a real fire risk. One of the more surprising points in LSU AgCenter's rodent guide is that mice nest inside appliances. Stoves, refrigerators, dishwashers and washing machines have warm, sheltered spaces in their bases and behind panels, often lined with insulation that mice shred for nests. They also chew wiring, and LSU notes that mice can carry the same diseases as rats. In a Shreveport kitchen, signs include droppings under or behind appliances, a musky smell when the oven warms up, chewed cords and shredded insulation near the base. Some people first notice a burnt smell or an appliance that stops working. The fix has a few steps. Pull appliances out carefully and clean behind them using wet methods: ventilate, spray droppings with bleach solution, soak 5 minutes, wipe up with paper towels. Seal gaps where pipes and wiring pass through walls behind appliances. Set traps along the walls nearby. If you find chewed wiring, have the appliance checked before using it again.

Trap spacing that works: LSU's 5 to 10 foot rule.

LSU AgCenter's guidance explains why. Mice hide anywhere and do not move far from their nests, so in a heavily infested area, traps or bait placements should go every 5 to 10 feet. In practice, that means lining the walls of an affected room. Put traps along baseboards, behind appliances, inside lower cabinets and in closets where you see droppings. Set snap traps with the trigger end facing the wall, since mice run along edges. Glue boards and traps are good choices where baits are not acceptable, such as kitchens and homes with children or pets. Check traps daily, wear gloves, and reset or move any trap that has not caught anything after several days. Remove catches promptly in Shreveport's heat. Trapping only works for good if the entry points are closed too. Seal gaps of 1/4 inch where mice are getting in. If traps keep filling after two weeks of dense placement, there are openings you have not found, and a provider can help track them down. Many people set one or two traps for mice and wonder why the problem continues.

Checking a Louisiana pest control license before you hire.

A license does not settle every question, but it does mean the people applying rodenticides have been trained and are accountable to the state. Louisiana regulates pest control through the Louisiana Department of Agriculture and Forestry and its Structural Pest Control Commission. Rodent work falls under two license categories: LP1, General pest control, and LP2, Commercial vertebrate control. Each business needs an annual place-of-business permit. LDAF lists the fee as $150 for businesses with two or fewer employees and $200 for three or more, and permits expire June 30 each year. Licensees recertify every three years. Technicians must be registered within 30 days of employment and complete at least 4 hours of recertification training each year. For a Shreveport homeowner, landlord or business, the check is simple. Ask the company for its place-of-business permit and the license number of the person responsible for your job. Confirm it covers LP1 or LP2. If a provider cannot or will not share those details, choose another one.

Rats along the Red River and in Shreveport attics.

Norway rats stay low. The Red River, its banks, nearby drainage ditches and creeks give them water and soft soil. They burrow along foundations, under slabs and beside sheds and enter homes through ground-level gaps. They forage widely, so a burrow near a drainage ditch can feed from trash cans and pet food several yards away. Roof rats climb. They are the usual attic rat along the Gulf Coast, and in Shreveport they reach rooflines by running along trees, fences and utility lines. Once inside, they nest in insulation and chew wiring. Control looks different for each. For Norway rats, focus on ground-level sealing to the LSU standard of 0.5 inch, burrow monitoring and tamperproof stations along foundations. For roof rats, trim branches back from the roof, seal eaves, vents and AC line gaps, and trap in the attic. With summer highs near 94F and mild winters, both species stay active year-round, so sealing pays off in any season. Shreveport deals with both rat species, and they live in different parts of a property.

Getting good rodent results on a budget in Shreveport.

The good news is that the most effective steps are also some of the cheapest. Start with sealing. LSU AgCenter says sealing all openings larger than 0.5 inch rat-proofs a building, and steel wool, hardware cloth and sealant are inexpensive. Focus on gaps around pipes, under doors, at the garage and behind appliances. Next, trap densely. Snap traps are cheap, and LSU's 5 to 10 foot spacing for heavy mouse activity works better than a couple of expensive devices. Check them daily. Cut off food and water. Store food in sealed containers, keep pet food off the floor at night, fix leaks and keep trash lidded. Spend on a provider where it counts: roof rat work high on the roofline, Norway rat burrows near the foundation, or a problem that does not respond to your own sealing and trapping. Ask for a quote that separates sealing, trapping and cleanup, so you can handle some parts yourself and hire out the rest. With a median home value around $145,000, many Shreveport households want effective rodent control without a large bill.

Simple ways to keep rodents away

• Seal all openings larger than 0.5 inch, and gaps of 1/4 inch where mice are a problem.
• Pull out the stove and refrigerator twice a year to clean and check for droppings.
• Seal gaps where pipes and wiring enter behind appliances.
• Store food in sealed containers and keep pet food off the floor overnight.
• Trim branches and vines back from the roof.
• Keep garbage in lidded cans and away from the house.
• Clear debris and dense brush along foundations and drainage areas.
• Fix leaking faucets and AC drain lines, since rodents need water.
