With their vibrant flowers and lush foliage, Barbara Karst bougainvillea plants make a gorgeous addition to warm climate gardens However, these ornamentals can sometimes attract unwanted attention from rodents like rats, mice, voles, and squirrels Rodents are drawn to the plants as potential food sources and shelters. They may gnaw on roots, stems, leaves, and flowers, causing unsightly damage. Use these tips to deter rodents and protect your beloved Barbara Karst bougainvilleas.

Understand Rodent Behavior

• Rodents are opportunistic feeders attracted to easily accessible plant parts and dropped fruits or flowers They also seek out hiding spots amid dense growth

• Gnaw marks on branches and chewed up plant debris reveal their presence. Look for burrows at plant bases. Seek out entry points like gaps under fences.

• Activity increases in fall as rodents seek shelter from cold weather. Hungry juveniles also forage more aggressively.

• Certain rodents are more problematic than others. Voles and squirrels cause more damage than mice. Rats are bolder and travel further distances.

Reduce Appeal and Access

• Choose open, sunny planting sites away from wood or rock piles and overgrown areas where rodents nest.

• Space plants widely to eliminate hiding spots. Use trellises to lift vines off the ground.

• Keep the garden free of leaf litter, weeds, and debris that attracts rodents looking for food and shelter.

• Eliminate food sources like fallen fruits/flowers. Use rodent-proof compost bins. Keep pet food indoors.

• Set up physical barriers using hardware cloth planted 1 ft down. Install wire mesh guards around plant bases.

• Fill gaps in fences with concrete or wire mesh. Seal entry points into garden structures. Metal flashing deters climbing.

Use Tactile and Smell Repellents

• Sprinkle rough pea gravel, pinecones, or sharp mulch around plants to deter rodents from digging and burrowing.

• Interplant aromatic herbs like mint, thyme, lavender and sage. Strong scents deter rodents.

• Sprinkle used cat litter around plants. The smell of potential predators triggers fear.

• Use garlic, chili pepper, or ammonia soaked rags. Strong odors repel rodents. Reapply after rain.

• Scatter human hair, human urine, and predator urine like coyote or fox. Rodents sense the smell of possible threats.

Employ Electronic Repellers

• Ultrasonic devices emit high-frequency sounds only heard by rodents. Effective range is 15-20 feet.

• Electromagnetic and battery-operated vibration repellers work by mimicking predator vibrations.

• Solar-powered spike lights flash randomly at night, frightening nocturnal rodents.

• Always use multiple units and move periodically so rodents don’t acclimate. Position near plants and high rodent activity.

Apply Deterrent Sprays

• Make all-natural sprays from hot pepper, garlic, and soap. Coat plant parts to deter chewing. Reapply after rain.

• Use commercial animal repellent sprays made with pungent oils, sulfur, pepper, and mint oils. Follow label instructions.

• Avoid synthetic pesticides which may harm pollinators and beneficial insects. Seek wildlife-safe products.

Set Live Traps as a Last Resort

• Bait with peanut butter, sunflower seeds, or grains. Place traps along high traffic areas near damage.

• Cover traps with burlap or cardboard to appear like a sheltered tunnel. Check traps twice daily.

• Release non-target animals immediately. Relocate captured rodents >10 miles away in suitable habitat.

• Be aware that rodents are very intelligent. Trapping rarely solves problems long-term if their needs aren’t addressed.

Prioritize Prevention

When dealing with rodent pests, an ounce of prevention is truly worth a pound of cure. Focus first on exclusion methods to deny access. Reduce appeals like food and shelter. Use repellents as added protection. Trapping should only be a last resort once you’ve addressed the source factors drawing rodents to your beloved Barbara Karst bougainvillea in the first place.
