Rabbits, packrats, and javelina — identify the animal first, then fix the access.
Most "something is eating my plants" calls in the Valley come down to three animals with completely different solutions. Guess wrong and you spend a season on the wrong fix. Read the damage, then choose exclusion — because in desert wildlife management, physical barriers are the only thing that reliably holds.

01
Read the damage
- Rabbits: clean 45-degree angled cuts on young stems, damage concentrated below about knee height, bark stripped from young trunks.
- Packrats (white-throated woodrats): a large stick-and-debris midden, chewed irrigation lines, and shiny objects collected into the nest.
- Javelina: rooting and torn-up beds, whole plants pulled out, crushed drip line, and a strong musky odor.
- Ground squirrels: clean holes without a mound and daytime activity; gophers push up crescent mounds.
- Birds and rodents both take fruit — but a rat leaves the rind hanging on the tree.
02
Rabbits
- Hardware cloth or one-inch mesh fencing at least two feet tall, buried or pinned several inches at the bottom.
- Trunk guards on every newly planted tree — a young tree can be girdled in one night.
- Cage new plants for their first year; established shrubs usually survive browsing that kills new ones.
- Repellents rotate in effectiveness and wash off with irrigation and rain; treat them as temporary support to a barrier.
- Choose lower-preference plants near unfenced edges rather than replanting the favorite over and over.

Packrats — the expensive one
- Packrats chew vehicle wiring, and a nest in an engine bay is a genuinely costly problem.
- Remove middens with gloves, a mask, and a hose rather than dry sweeping; rodent nest material is a respiratory hazard.
- Clear the harborage: brush piles, dense prickly pear skirts, stacked material, and untrimmed low shrub interiors.
- Screen and seal shed openings, and store nothing shiny or edible on the ground.
- Snap traps in the right locations are more effective and far safer than poison bait.
- Rodent poison also kills the owls, hawks, and coyotes that would otherwise keep rodent numbers down — this is the single most common way people make their rodent problem permanent.
04
Javelina
- Javelina are strong, they travel in groups, and they are not deterred by a low decorative barrier.
- Solid block wall is what actually works. Wrought iron with a solid base panel is the next best thing.
- Never feed them, deliberately or by leaving fallen fruit, pet food, and open trash out.
- They target succulent, high-water plants — agave hearts, cactus pads, and freshly installed annuals.
- Lower-preference planting plus a real barrier is the plan; repellent alone will not hold.
- Keep dogs separated from javelina. Encounters go badly for both animals, and javelina defend themselves.
05
Design choices that reduce the whole problem
- Protect new plantings for the first year, every time — that is when damage does permanent harm.
- Drip line placement matters: exposed tubing across open ground is a chew target for everything.
- Keep fallen fruit picked up and compost enclosed.
- Leave the raptors and snakes alone; they are doing rodent control for free.
- If an animal keeps returning, look for what it is coming for. Something in the yard is worth the trip.
FAQ
Common questions.
Read the cut. Rabbits leave clean angled cuts below knee height and strip bark from young trunks. Javelina root, tear, and pull whole plants out. Packrats chew irrigation line and build a stick midden nearby. Ground squirrels and gophers leave holes and mounds. Each one needs a different fix, so identify before you buy anything.
Hardware cloth or one-inch mesh at least two feet tall, with the bottom buried or pinned several inches into the ground so they cannot push under it. Add individual trunk guards on young trees, since a rabbit can girdle a new tree in a single night.
Remove the habitat near where you park — brush piles, stacked material, dense low shrub skirts — and clear any midden you find using gloves, a mask, and water rather than dry sweeping. Snap traps in the right spots work; poison bait creates a dead rodent in an unknown location and poisons the predators that were helping you.
There is no truly javelina-proof plant, but they concentrate on succulent, high-water material — agave hearts, cactus pads, and new annuals. Tougher, aromatic, low-water shrubs are lower on their list. In practice a solid wall does more than any plant selection.
We do not recommend it. Poisoned rodents are eaten by owls, hawks, coyotes, dogs, and cats, and secondary poisoning removes the predators that were controlling rodents for free. Exclusion, habitat removal, and trapping solve the problem without creating a second one.
