How Landlords Can Prevent Phrogging in Rental Properties?

Phrogging isn’t something most landlords expect — but it’s something more of them are dealing with. It causes real problems: damaged property, nervous tenants, and unexpected costs. And the worst part? It often goes unnoticed for too long.

If you rent out homes or manage units, you can’t afford to ignore this. Prevention isn’t complicated, but it does take some awareness and a few smart steps. 

This blog covers how to spot the warning signs early and protect your property before it turns into a headache.

Warning Signs of Phrogging in Rental Properties

Here are some warning signs of phrogging. 

1. Strange Noises When the Property Should Be Empty

If tenants report hearing footsteps, soft banging, or doors opening and closing when no one’s supposed to be home, don’t brush it off. Phroggers often move quietly and mostly at night, but small mistakes give them away. 

Consistent unexplained noises — especially in attics, basements, or closets—could mean someone is secretly living there. Take tenant complaints seriously and check the space thoroughly.

2. Lights or Electronics Turning On by Themselves

It’s easy to ignore a light turning on or a TV flickering. But if it keeps happening in an empty or unused unit, it could be a sign someone is hiding inside. Phroggers may use electronics when they think no one’s watching. If tenants report strange power use or you see signs during inspections, don’t assume it’s just a glitch — look deeper.

3. Unexplained Increase in Utility Bills

A sudden spike in electricity, gas, or water bills—especially in a vacant unit—is a big red flag. Even a small increase can mean someone is secretly using appliances or plumbing. Phroggers rely on the assumption that no one checks these details. As a landlord, monitor utility usage patterns, and if something looks off, investigate quickly.

4. Items That Go Missing or Get Moved Around

Tenants might think they misplaced something at first, but when things keep moving or disappearing, it’s time to be alert. Phroggers often touch or use items when the space is empty. Small thefts or strange rearrangements of furniture can be clues. Encourage tenants to speak up if something feels off, even if it seems minor.

5. Damaged or Tampered Entry Points

Loose locks, scratched door frames, cracked windows, or disturbed crawl spaces are more than just wear and tear — they might be signs of unauthorized entry. Phroggers often get in through less obvious points like back doors or attic windows. Inspect your property closely during tenant turnovers and keep all access points secured and regularly maintained.

Practical Ways to Prevent Phrogging as a Landlord

You can follow these tips to prevent phrogging.

Secure Every Entry Point—Not Just the Front Door

Phroggers often enter through places most people ignore—like basement windows, attic vents, or backdoors. As a landlord, it’s your job to make sure all potential entry points are locked and reinforced. Install deadbolts on all doors, use window locks, and seal off crawl spaces or unused areas. 

Even small openings, like pet doors or loose screens, can be used to sneak in. Walk through your property regularly and look at it the way a trespasser would. If something looks easy to get into, fix it before someone else notices.

Install Security Cameras with Remote Access

Security cameras are one of the best deterrents for phroggers. Place them around key areas—entryways, hallways, stairwells, and especially vacant units. Use cameras that offer real-time alerts and remote viewing so you can check in anytime. Most modern systems are affordable and easy to install. Even a visible camera can scare off someone thinking of sneaking in — in fact, 60% of burglars say they avoid homes that have visible cameras. 

If the unit is empty, a few indoor cameras with motion detection can catch movement immediately, helping you act before the situation gets worse. Always make sure your tenants are aware of any shared surveillance for transparency.

Do Regular Property Inspections

Make property inspections part of your routine, not just something you do when tenants move out. Phroggers rely on being unnoticed—so if you check the property often, you reduce their chances. 

For long-term tenants, schedule a quarterly walkthrough and look for any damage, tampered locks, or signs of forced entry. For vacant units, do quick weekly check-ins to make sure no one has entered without permission. Keep notes or photos of each visit so you can track changes over time. Just your presence alone can help keep unauthorized people away.

Use Smart Tech Like Motion Sensors and Smart Locks

Smart home devices can give you an extra layer of security without needing to be on-site. Motion sensors can alert you to unexpected movement, especially in basements, garages, or unused rooms. 

Smart locks let you control access remotely, track who enters and leaves, and change codes instantly between tenants. These tools not only make things easier for you but also stop potential phroggers from sneaking in unnoticed. If anything seems unusual — like a door unlocking at odd hours — you’ll know right away and can take action.

Educate Your Tenants to Report Suspicious Activity

Your tenants are your eyes and ears. If they know what to look for, they can help catch a problem early. Let them know about the risk of phrogging in a simple, non-scary way. Ask them to report anything strange — like hearing footsteps, seeing people who don’t belong, or noticing things moved around. 

You can also include a quick security reminder in your monthly emails or rent receipts. When tenants feel involved and informed, they’re more likely to speak up—and that can make all the difference in stopping phrogging before it gets serious.

Keep Vacant Units Unfurnished and Locked Down

Phroggers target empty homes because they’re easy to hide in, especially if they look lived-in. If a unit is vacant, don’t leave behind furniture, appliances, or boxes that could make it comfortable to squat in. Clear the space, lock all windows and doors, and check in often. 

You can also leave a visible “under surveillance” sign or even set up a basic alarm system to keep intruders out. The more unwelcoming the space looks to a phrogger, the less likely they are to try sneaking in.

Work With Neighbors and On-Site Staff

If your rental is part of a building or complex, having extra eyes around helps. Let nearby neighbors or on-site staff know when a unit is empty or under renovation so they can alert you if something seems off. 

A phrogger’s goal is to go unnoticed, so community awareness is a powerful defense. Even just one neighbor asking, “Who are you?” can stop them. Build relationships with people nearby and make sure they know how to reach you quickly if they suspect something. It’s a small step that adds a lot of security.

Conclusion

Phrogging is a real risk that can cause damage, stress, and safety issues in rental homes. As a landlord, staying alert and taking a few basic steps can make a big difference. Lock all entry points, inspect regularly, use smart tools, and stay in touch with your tenants and neighbors. 

Small efforts now can save you from bigger problems later. Keep your property secure, and don’t leave anything to chance.

FAQs

What’s the best way to secure a vacant rental property?

Use deadbolts on all doors, lock all windows, and seal off less obvious entry points like crawl spaces or basements. Add motion sensors or security cameras if possible. Avoid leaving furniture or appliances inside, and check the property regularly until it’s rented again.

Can security cameras really help prevent phrogging?

Yes. Visible cameras can scare off intruders, and motion alerts let you respond quickly if someone enters. Cameras placed at entry points and inside vacant units can catch unusual activity early and provide evidence if needed.

Should I talk to tenants about phrogging?

Yes. Let them know to report strange noises, people they don’t recognize, or items moving without explanation. A quick conversation or written reminder can make tenants feel safer and keep you informed about any red flags.

How often should I inspect my rental property?

Inspect vacant units weekly and do quarterly walk-throughs for occupied ones. These visits help spot tampered locks, unusual changes, or damage early on. Regular check-ins also show that the property is being monitored, which discourages intruders.

What should I do if I suspect someone is living in the unit secretly?

Don’t confront anyone yourself. Call local law enforcement and wait for them to handle it. Document anything unusual and secure the area once cleared. If you find damage or signs of forced entry, report it and take steps to prevent it from happening again.
