Ants and roaches in a rental often point to two things: water and an easy way in. A few habits that help keep a rental pest-free:

1. Fix the drips first. Leaky faucets, slow drains and damp under-sink cabinets draw pests. Fix them as soon as a tenant reports them, not at the next turnover.

2. Seal the gaps. Check door sweeps, window screens and gaps around pipes and utility lines so pests have fewer ways inside.

3. Put it in the lease. Spell out how tenants report pests and who arranges treatment, then follow that process every time.

4. Use a licensed pro. Hire licensed pest control, give the tenant proper notice before entry, and keep a written record of each visit. California habitability standards cover pests, so confirm what applies to your property.
