Getting rid of rats in a Lubbock, TX home requires three things done in the right sequence: identifying which species you have (roof rat or Norway rat), eliminating the active population, and sealing the entry points that allowed them in. This guide covers all three steps for a Lubbock homeowner dealing with a rat infestation, including what works, what doesn't, and when a professional program produces better outcomes than DIY.
Step 1: Identify the species.
The treatment approach for a roof rat in your attic and a Norway rat in your foundation burrow are not the same. Treating the wrong way wastes time and money. Species identification from evidence: roof rat droppings are 1/2 to 3/4 inch, spindle-shaped with pointed ends, found in elevated locations. Norway rat droppings are larger, blunt-ended, found at ground level. Roof rat activity comes from overhead; Norway rat activity comes from the foundation perimeter and ground level. See our full species identification guide for the complete comparison.
Step 2: Assess the infestation extent.
Before starting any treatment, understand the scope of what you're dealing with. For roof rats: inspect the attic from the access opening. Look for droppings on top of the insulation, disturbed or matted insulation, and nesting material. If droppings are visible from the access opening without entering, the infestation has been active long enough to produce evidence in the most accessible area — the actual colony is likely deeper in. For Norway rats: walk the full foundation exterior and look for burrow openings (2–3 inch diameter holes with fresh soil disturbance at the entrance), grease marks along the foundation base, and any sewer drain or drain-cover gap near the home's perimeter.
Step 3: Treatment — baiting vs. trapping.
Both approaches work; the choice depends on your situation. Snap traps are effective for roof rats in attics when placed along confirmed runways (on attic beams, not on the insulation surface) and in the right orientation (trigger end facing the wall). They require regular checking and carcass removal. The advantage is that you can account for every captured animal and there's no secondary poisoning risk. Bait stations with rodenticide are effective for both species when placed in tamper-resistant stations on confirmed runways. They work passively and cover more territory than snap traps. The disadvantage is that animals may die in inaccessible locations, and there's a secondary poisoning risk if a poisoned animal is consumed by a pet or raptor before it dies.
For a DIY roof-rat attic program: snap traps on attic beams, oriented along confirmed runways, checked every 2–3 days. Place 6–8 traps for a standard residential attic. For a DIY Norway rat program: snap traps along the foundation perimeter near burrow openings, or exterior bait stations if you have a tamper-resistant station. Consumer-grade exterior bait stations are not rated for tamper-resistance in the same way as commercial-grade stations, which creates a pet-safety concern if dogs or cats have access to the perimeter.
Step 4: Exclusion — the step that prevents recurrence.
This is the step most DIY programs skip. Treatment eliminates the current population. Exclusion closes the access points that allowed them in. Without it, the problem repeats. For roof rats: hardware cloth on all soffit vents, blocking at fascia-sheathing gaps, foam-and-mesh at pipe chases. For Norway rats: concrete patch at foundation cracks, hardware cloth at foundation vent openings, sealed drain covers. See our exclusion service guide for materials and approach by location type.
Step 5: Follow-up verification.
Treatment programs require follow-up verification to confirm the infestation is fully resolved, not just reduced. The standard verification for a roof-rat program is a droppings inspection 10–14 days after treatment starts: no new droppings in previously active areas means the population has been eliminated. For a Norway rat program: no new burrow activity (fresh soil disturbance) at the foundation perimeter 10–14 days after treatment.
When to call a professional.
DIY programs are most appropriate for single-species, early-stage infestations in accessible locations. Call a professional when: you have activity in the attic and aren't comfortable entering it safely, you have evidence of both species simultaneously, the infestation has been active for more than a few weeks (established colonies don't respond as well to single-trap-deployment programs), or DIY treatment has been running for 2+ weeks without reducing activity. Our rat control service covers all five steps above in a structured program with follow-up verification included.
| Scenario | DIY appropriate? | Professional recommended? |
|---|---|---|
| Early attic intrusion, 1–2 rats, fresh droppings only | Yes, with caution | Optional |
| Established attic colony, nested insulation | No | Yes |
| Norway rats, foundation burrows | Possible for limited scope | Recommended |
| Multi-species (rats + mice) | No | Yes |
| Commercial or multi-unit property | No | Yes |
