Hey everyone!
I’m struggling with rats wreaking havoc in my vegetable greenhouse. They’re nibbling on seedlings, digging up root systems, and even chewing through irrigation lines! I’ve tried snap traps and peppermint oil, but they keep coming back. With my tomato crop at risk, I need safe, effective solutions that won’t harm my plants or beneficial insects.
Rats hate hardware cloth! Line the greenhouse floor and walls with 1/4-inch mesh. Bury it 12 inches deep outside to block burrowing. Also, elevate compost bins on cinder blocks, no more rat buffets!
@EcoGrower Brilliant! Did you seal the greenhouse door edges too? Mine has a small gap at the bottom.
Bucket traps with sunflower seeds + water work wonders. Rats jump in for the seeds and drown. Place them near entry points, away from planters.
Plant mint around the greenhouse perimeter, rats despise the smell. Indoors, use clove oil sprays on non-edible surfaces. Reapply after watering!
Rats invade greenhouses in fall/winter for warmth. Preemptively install heated rodent deterrent mats under doors. They deliver mild shocks but safe for humans.
Skip poison, it risks contaminating soil. Use live traps with peanut butter, then relocate rats 2+ miles away. Check local laws first!
Rats chew drip lines for water. Switch to copper tubing, they hate the taste! For gaps, seal with silicone caulk + steel wool.
Sprinkle cayenne pepper powder around seedlings. Rats avoid the heat, but plants don’t mind! Mix with garlic powder for extra punch.
Install solar-powered motion lights inside. Rats flee the sudden brightness. Pair with wind chimes for noise deterrence!
Update: Lined floors with hardware cloth + set bucket traps. Caught 5 rats in a week! Anyone try biological controls like barn owls?
Owl boxes nearby cut my rat population by 80%! Also, remove weeds around the greenhouse, they’re rat highways.
Rats basically treat greenhouses like luxury resorts—warm temperature, food everywhere, little disturbance. As the article says: remove attractants, close entry points, and then set traps.
I found it helped to store seeds, soil bags and amendments in sealed metal containers raised off the floor.
Clutter and piles of unused trays or cardboard are rodent-nesting gold in greenhouses. Clearing that out reduces shelter and helps your trap plan.
Puddles or dripping hoses draw rats in. Fixing water issues helps break their comfort zone.
@SeedlingSaverSara I did something similar, raised shelving, metal tubs for soil, and I moved the compost out of the greenhouse entirely. Saw fewer rat signs afterwards.
Fine-mesh scrims around vents and burying hardware cloth around the perimeter are long-term barriers. Rats will dig under if you don’t.
You don’t have to invest in high-tech gear. A tight seal on the door, a few good traps, and good housekeeping go a long way in a greenhouse setup.
Even when things seem clear, keep monitoring: fresh droppings, chewed soil bags, disturbed trays, they tell you rats might be coming back. It’s not a one-time job.
