How to apply tar for mice? - briefly
Spread a thin, even coat of petroleum tar onto a disposable pad and position it in suspected mouse pathways, ensuring contact with walls or entry gaps. Refresh the tar periodically to sustain its adhesive and toxic properties.
How to apply tar for mice? - in detail
Applying tar as a rodent‑control agent requires preparation, precise placement, and safety precautions. Begin by selecting a petroleum‑based tar with a high viscosity; low‑viscosity products spread too thinly and lose adhesive strength. Wear chemical‑resistant gloves, goggles, and a mask to prevent skin contact and inhalation of fumes.
- Identify entry points and travel pathways: examine walls, baseboards, and concealed gaps for signs of gnaw marks or droppings. Mark each location with a removable indicator.
- Clean surfaces: remove dust, grease, and loose debris with a solvent‑free detergent, then dry thoroughly. A clean substrate ensures maximum adhesion.
- Prepare the tar applicator: heat the tar in a metal pot on low flame until it reaches a pourable consistency (approximately 150 °C). Stir continuously to prevent scorching.
- Apply a thin, continuous bead (2–3 mm thick) along each marked line using a stainless‑steel spatula or a specialized tar dispenser. Ensure the bead bridges the gap completely, leaving no gaps for mice to bypass.
- Allow the tar to cure for 30–45 minutes. During this period, restrict access to the treated area to avoid disturbance.
- Monitor effectiveness: check for fresh gnaw marks or droppings after 24 hours. Reapply tar to any compromised sections.
Safety considerations include storing unused tar in a sealed, fire‑proof container, disposing of contaminated gloves and sponges in accordance with hazardous‑waste regulations, and keeping the area well‑ventilated during heating and curing. For environments where tar may damage surfaces, consider using a non‑sticky barrier (e.g., steel wool) in conjunction with the tar bead to protect finishes while retaining rodent‑deterrent properties.
Regular inspection every two weeks helps maintain an uninterrupted barrier, reducing the likelihood of re‑infestation.
