Hiring a pest control prowhat to ask and when to book
General pest control covers ants, spiders, roaches and rodents, usually on a quarterly plan. Termite treatment and wildlife removal are separate licenses in most states, and a company may do one without the other.
Ask what the plan covers, how re-treatments between visits are handled, and whether exclusion work like sealing entry points is part of the service.
Ant and wasp calls peak in late spring and summer; mice and rats move indoors in fall.
Questions worth asking
Every pest control listing on this directory shows the owner's answer to one trade question when they have given it: Termites and wildlife, or general pests only? Along with free estimates and after-hours availability, that answer is labeled "owner reported" with the date we asked.
