Pests like roaches, ants, and millipedes are masters at finding the smallest gaps in your home’s defenses. One of their favorite secret passages? Dry drains. When water in your P-traps evaporates, it creates an open highway straight into your kitchen, bathroom, or laundry room.
How Pests Enter Your Home
Dry Drains and Sewers
P-traps under sinks and tubs rely on a water seal to block sewer gases—and pests.
When drains aren’t used for weeks, that water evaporates. Roaches, drain flies, and other insects slip right up through the pipes.
Cracks and Gaps in the Foundation
Hairline fissures in concrete allow ants, centipedes, and even small rodents to enter.
Seasonal ground shifts in Florida can open and close these gaps over time.
Gaps Around Doors and Windows
Missing weatherstripping or damaged door sweeps create a 1/16-inch gap—large enough for roaches, spiders, and millipedes to fit.
Older windows without tight seals let pests in, especially during warm, humid nights.
Utility Lines and Vents
Cable or plumbing penetrations that lack proper sealant are unfiltered highways.
Dryer vents and attic fans without screens can welcome wasps, rats, and tree frogs.
Prevention Strategies Every Homeowner Can Implement
Maintain Your Drains
Run water into little-used sinks and tubs weekly.
Install clip-on drain covers to catch debris and block insects.
Seal Cracks and Gaps
Use silicone caulk on foundation fissures and around pipe entries.
Replace worn weatherstripping on doors and install door sweeps.
Keep Perimeter Clear
Trim back landscape at least 12 inches from your foundation.
Move firewood, mulch, and debris piles away from exterior walls.
Maintain Indoor Cleanliness
Wipe up spills immediately and store food in sealed containers.
Vacuum crumbs and pet food every day to remove attractants.
Don’t forget about cleaning out interior trash can and cabinet
