The answer to 'cricket trails' is that cricket trails are a common pest problem that can indicate the presence of crickets in or around your home. Crickets leave behind visible trails as they move around, which can be a sign of an infestation. Symptoms include seeing the trails, as well as hearing the distinctive chirping sounds of crickets.
To address cricket trails, you can try some DIY solutions like sealing cracks and crevices where crickets may be entering, using insecticide sprays or baits, or setting out traps. However, if the infestation is severe or you're unable to get it under control, it's best to call in a professional pest control technician who can properly identify the species and implement effective treatments.
