Rocky ground changes the strategy, not the animals

Standard rodent work is three things: remove what feeds them, remove what shelters them, and close the building. On broken ground the middle one is mostly unavailable.

What rock provides that you can't take away:

Crevices, ledges, and gaps under slabs of stone — dry, temperature-buffered shelter that needs no digging
Rock piles, retaining walls, and rip-rap on a slope, which are the same thing with a landscaper's name on it
Brush and cactus growing out of rock, which is cover on top of cover
Voids under and behind rock that you can't inspect, so you never really know the population size

What that means practically:

Stop trying to win on the ground and win on the building. Every opening closed in metal is worth more here than on a flat lot, because the reservoir outside is permanent
Assume ongoing pressure rather than a one-time event. A rocky lot doesn't get "cleared" — it gets held
Judge results by what's inside, not by whether you still see rodents outside. On this kind of property you will
The things you CAN control still matter — stored material off the ground, firewood away from the house, trash lidded, feed and pet food in sealed metal, drips fixed, and any vegetation you actually can cut back off the walls
Retaining walls and rock landscaping deserve a look where they meet the foundation. That junction is a covered path from permanent shelter straight to your envelope

Pack rats are the animal most at home in this — they nest in rock crevices as readily as in a shed, and a midden of sticks, cactus, wire, and foil is the tell. Exclusion & proofing » · Every entry point »

Before we can get there: the first day or two

We're being straight with you — Big Spring is roughly sixty miles from us, and a drive that long means a scheduling window, not a same-hour arrival. Call for details on scheduling and service area coverage.

So here's what's worth doing yourself while you wait. None of it is a substitute for the work, but it prevents the problem from getting bigger.

Cut off the food tonight. Everything edible into sealed metal or rigid containers — pantry staples, pet food, feed, bird seed. Trash lidded, nothing bagged outside overnight, dishes not left out. A population without food stops growing.
Cut off the water. Fix dripping faucets and hose bibs, empty pet bowls at night, wipe down sinks and tubs. In this climate that's a real lever.
Find the traffic, don't guess at it. Droppings, gnaw marks, rub marks on baseboards, and greasy smudges tell you where they travel. Clean one area completely and note the date — if fresh droppings appear in two or three days, it's active there. Droppings ID »
Set traps, and set more than feels right. Snap traps along walls with the trigger side toward the wall, in the places the evidence pointed you at, kept away from pets and children. Under-trapping is the single most common DIY mistake. How to do it properly »
Close the obvious gaps temporarily — a rolled towel at a door gap will do overnight. It is not a repair, and it should be replaced with metal, but it slows traffic tonight.
Look at your garage door with it closed, from outside, with a light. Bottom corners first. That's the number one entry point in this whole region and it's often visible in ten seconds.
Don't put out poison. It's the one action that makes the next two weeks worse rather than better — see below.
Don't dry-sweep or vacuum droppings. Wet them down with a disinfectant solution, gloves and a proper mask, bag them wet. Cleanup method » (general safety information, not medical advice)

Photograph anything that looks like damage, dated, before you clean or move it. If a landlord, an insurer, or a contractor conversation is coming, you'll want it.

What else makes Big Spring different

Older housing stock in the established parts of town — deteriorated mortar, tired thresholds and door sweeps, and openings that have usually been patched at least once with something that didn't hold. The full inventory of that problem is here: older homes and failed patches »

Slope and drainage. Broken ground means houses sit on grade changes, and a downhill side with a crawl space, a stepped foundation, or a retaining wall gives you junctions a flat slab doesn't have. Most Odessa-area homes are slab-on-grade, but out here it's worth actually looking rather than assuming.

The I-20 corridor, with lodging, restaurants, truck stops, and fuel and freight operations concentrating dumpsters and food waste — the reliable Norway rat driver in any town along the interstate. Commercial rodent control » · Restaurant rodent control »

A genuine wildlife edge. Where a neighborhood backs onto broken country, the transition is abrupt rather than gradual — which puts desert species against houses directly. Pack rats · Deer mice · Cotton rats where there's grass.

What we find most in Big Spring

House mice — the most common animal inside anywhere, and the first through a gap when a cold front hits. Droppings ⅛–¼ inch, rice-sized with pointed ends. House mice »
Pack rats — the signature animal of rock and brush country. In crevices, sheds, stored equipment, and under vehicle hoods. Pack rats »
Norway rats — ground level, around food waste, the interstate corridor, and water. Burrows 2–4 inches with a fan of excavated dirt; droppings ½–¾ inch, thick with blunt ends. Norway rats »
Roof rats — where there's mature landscaping and a reachable roofline. Droppings about ½ inch, slimmer and curved, found in the attic and on rafters. Roof rats »
Deer mice — likely on the edges of town and in outbuildings. Never dry-sweep droppings or nesting material. Deer mice » · Health risks »
Cotton rats — in grassy ground, entering structures after mowing or clearing. Cotton rats »

What we do on a Big Spring job

Inspection of the full envelope plus the surrounding ground — including rock, walls, and slope junctions, and an honest read on what can and can't be removed. Rodent inspection »
Species ID — pack rats, house mice, Norway rats, and roof rats are four different jobs at different elevations.
Trapping on real runways and travel routes, out of reach of pets and children. Pet-safe »
Exclusion in metal, and thoroughly, because it's carrying most of the weight here — thresholds and sweeps, garage door bottom corners, slab edge, penetrations, weep hole covers, vents, fascia and soffit corners. Galvanized hardware cloth, sheet metal, and mortar hold. Expanding foam and steel wool don't — foam gets chewed and steel wool rusts and pulls out.
A realistic plan for the outside, covering what's worth changing and what isn't. We'd rather tell you the rock stays than sell you a fantasy about clearing it.
Cleanup and decontamination — wetted, never dry-swept or shop-vacuumed. Droppings cleanup »
Follow-up verification. We come back and confirm zero activity rather than reduced activity, and the points we sealed are re-checked at the same time.

We do not do electrical, HVAC, or roofing repair. Chewed wiring and damaged ductwork get photographed and referred to a licensed trade.

Frequently asked questions

Why can't I get rid of the rodents outside my house on a rocky lot?

Because rock is permanent harborage. Crevices, ledges, rock piles, retaining walls, and the voids underneath them provide dry, temperature-buffered shelter that needs no digging and can't be mowed, cleared, or hauled away — so the population outside doesn't go to zero the way it can on a flat lot with removable cover. The realistic goal on this kind of property is a building they can't get into, plus removing the food and water you do control. Judge the result by what's inside, not by whether you still see activity outside.

Do you drive out to Big Spring?

Call for details on scheduling and service area coverage. It's roughly sixty miles east on I-20.

What should I do tonight if I can't get anyone out for a day or two?

Cut off food and water first — everything edible into sealed metal or rigid containers, trash lidded, drips fixed, pet bowls emptied at night — because a population without resources stops growing. Then follow the evidence rather than guessing: droppings, gnaw marks, and rub marks show you the travel routes, and clean one area completely and note the date so you can tell in two or three days whether it's still active. Set more snap traps than feels necessary along walls in those spots, away from pets and children, and block obvious door gaps temporarily with a rolled towel — which is a stopgap, not a repair. Don't put out poison, and don't dry-sweep or vacuum droppings.

Are pack rats different from regular rats?

Different animal, different job. Pack rats are native woodrats that collect material and build a bulky nest — a midden of sticks, cactus, wire, foil, and shiny objects — usually in rock crevices, brush, sheds, stored equipment, or under a vehicle hood, with heavy urine staining. They're not a food-waste animal like a Norway rat and they're not an attic animal like a roof rat, so trap placement and the exclusion priorities are different, and vehicle wiring damage is the expensive risk with them specifically.

Will a rock retaining wall or rock landscaping cause a rodent problem?

It doesn't cause one, but it will sustain one, and where it meets your foundation it creates a covered route from permanent shelter directly to your building. You usually aren't going to remove it, so the answer is to seal that junction and the envelope above it properly in metal, keep stored material and firewood away from it, and cut back anything growing out of it that touches a wall. It's also worth inspecting that whole junction rather than assuming it's solid — it's one of the more commonly missed areas on a sloped lot.

Is Big Spring's rodent situation the same as Odessa's?

The animals overlap heavily and the buildings fail in the same places, so most of the method transfers. What's different is the ground: broken, rocky terrain provides shelter that can't be removed, houses sit on grade changes with junctions a flat slab doesn't have, and a neighborhood backing onto open country meets that country abruptly rather than gradually. Practically, that shifts more of the work onto exclusion and less onto habitat reduction than a typical in-town Odessa job.

Should I put out bait while I'm waiting for service?

No — it's the one thing that makes the following two weeks harder. Bait doesn't close the opening, so animals keep arriving from shelter you can't remove, and a poisoned rodent dies wherever it happens to be, which indoors usually means inside a wall or a ceiling. That turns a trapping job into an odor and cleanup job. Trap heavily, cut off food and water, and get the building closed in metal.
