Pest control terms explained
- Integrated pest management (IPM): inspect, identify, fix the cause, then use the least risky effective product
- Tamper-resistant bait station: a locked box that holds bait out of reach of children and pets
- Bait: a slow-acting food-based product that insects carry back to the nest
- Residual perimeter treatment: a product applied around the foundation and entries that keeps working for weeks
- Insect growth regulator (IGR): a product that stops young insects from becoming breeding adults
- EPA-registered label: the legal instructions for where and how a product may be used
- Monitoring: glue boards, traps and inspection logs that show whether the plan is working
- Exclusion: sealing gaps, installing sweeps and screening vents so pests cannot enter
Myths and facts
- Myth: natural means harmless. Fact: any pesticide, natural or not, should be used as the label directs.
- Myth: a clean house cannot get pests. Fact: pests follow food, water and shelter, and even tidy homes can have them.
- Myth: one treatment solves everything. Fact: many pests need a follow-up visit and fixes to entry points.
- Myth: spraying the ants you see ends the problem. Fact: baits that reach the nest work better and sprays can scatter a colony.
- Myth: pests only appear in summer. Fact: rodents, roaches and spiders stay active indoors in winter.
How a pest control visit works, step by step
Whatever is bothering you, a sound pest visit moves through the same stages in the same sequence. Once you know that sequence, it is easy to line companies up against each other and to notice when one jumps past the inspection and identification stages.
- Inspection: the technician walks the outside first (foundation, vents, utility lines, eaves, fence lines, mulch) and then the inside (kitchen, bathrooms, garage, attic or crawl space).
- Identification: the species is named from the insect, droppings, damage or trail, because the right product and method depend on it.
- Plan: we explain what will be done, which products or devices will be used, and what you need to do before and after.
- Treatment or exclusion: the work is done in the places the inspection found, not by spraying every room.
- Follow-up: you get a date for the next check and a clear answer on what to report if activity returns.
What makes pest control different in San Diego
Mild year-round weather keeps pests active in all seasons. Argentine ants are a constant in San Diego yards and kitchens; drywood termites are a structural concern.
Roof rats use palms and canyon edges; Norway rats appear near restaurants and the waterfront. Urban canyons and hillsides give pests wildlife corridors close to homes. What works in one climate or housing style can fall flat in the next, so ask us to explain how these local details shape the plan for your property.
