6 summer scams and how to avoid them Some scams never seem to get old.

 -- As the weather gets warmer, mosquitoes and ticks re-enter our lives, and along with them comes their larger cousin, the scam artist. There are ways to prepare for those seasonal meal stealers. The same goes for scams, as foreknowledge is the best repellent.

Ticks and mosquitoes aren’t harmless — they are well-known vectors for serious illnesses. Scam artists are also vectors for a plague that affects millions of people each year: identity theft. But sometimes a scam is of the simpler smash-and-grab variety.

Either way, some scams never seem to get old, as evidenced by the huge number of people that continue to fall for them no matter how many warnings we issue. There are always new variations that snare even the wariest consumers. With that, I give you this summer’s smorgasbord of scams.

1. The Summer Rental Scam It’s not the easiest thing on earth to find a summer rental that has all the right elements: a reasonable distance from the beach, the right number of bedrooms and bathrooms, a pets welcome policy. So, when you do find the right one, the tendency for most people is to pounce. Don’t be most people. If you get scammed on a rental, you’re not going to know till you show up at the front door and a puzzled person peering back at you. Oh yeah, and good luck finding the rental office, because it’s an abandoned drive-in.

The best thing you can do is visit the property in question beforehand. If you are working with a real estate agent, ask for his or her license number and check it, request references if there are no reviews online and confirm that the address is real and the premises are truly available for rent. Some home-rental websites have their own vetting processes and offer guarantees that will protect you in case of fraud.

2. Summer Job as Credit Application It is not completely bizarre to need a background check before getting hired, but chances are that the young person in your life looking for a summer job is not applying to be a bank clerk or armored car driver. When it comes to providing personally identifiable information to an employer, use your head.

It is sadly a common occurrence that when kids are offered a “job,” they provide their information for tax purposes, including their Social Security number, and then never hear back. The reason: The only “job” was a robbery. Their identity is stolen, and because kids will be kids, it often takes a long time for them to realize the jerk who flaked on a summer job offer gutted their creditworthiness.

Never provide sensitive personal information to a job site or anyone claiming to offer a job at the start of the process. Before you show up for an interview, make sure the job is legit: You can figure this out by doing an online search or making a few phone calls.

3. Door-Knocker Scams Summer is the time for door-knocking scams. It can be anything really. Sometimes the knocker wants you to help save an endangered species or an embattled population far away, sometimes they are selling a lawn service, home maintenance or sustainably-produced electricity — all these causes, services and products may be legitimate, but the person offering them … not so much.

If a stranger comes to your door, your level of suspicion should be high from a personal and digital security perspective. If you like what a knocker has to say, tell them that you will go online to help their cause or buy a product, and send them on their way.

4. Wi-Fi Scams This is a year-round thing, but people still get got all the time by phony Wi-Fi scams, and the problem is only getting worse now that more municipalities are offering free access to the internet. The problem is that free Wi-Fi doesn’t guarantee secure Wi-Fi.

Always check with the network provider or someone of authority before logging on to any new wireless connection. Use a VPN, or virtual private network, to conduct any transactions that involve sensitive information.

5. Front Desk & Fake Menu Scams Hotel scams are many and various, and it’s best just to remember that you are a target whenever you are traveling, but there are two scams that are sufficiently common. The first is the front desk scam, which is pretty simple.

You check in late, you’re tired and your phone rings. The scammer doesn’t know when you checked in. He or she is calling random rooms. You are told there is a problem with your credit card. Can you please confirm the number? The second scam to look out for is the menu scam. Scammers produce fake ones, and then steal your credit card information when you call to place an order.

If you get a call from the front desk, hang up and call back or go in person to confirm your payment method. Use your smartphone to order food or call the front desk for suggestions.

6. Moving Scams Summertime is moving time. Just make sure your relocation isn’t a moving experience of the hair-pulling kind. While there are many great services out there, there are also some fraudulent ones that could wind up costing you big time.

With new online services like Task Rabbit and Angie’s List to name but two, there are ways to choose a moving service, large or small, that suits your needs and provides reviews. Just make sure you check out their reputation online before they show up at your door.

You May Have Identity Theft Repellent Just as mosquitoes can ruin a summer picnic, a good scammer can turn a winning day into a master class on losing your mind as bank accounts are drained, credit cards are maxed out and large purchases are made in your name. There’s a way out, and you may already be covered.

If you think you might have been a victim of identity theft, it’s important to monitor your credit for anything out of the ordinary — primarily accounts and delinquencies you don’t recognize. You can get a copy of each of your three major credit reports for free once a year at AnnualCreditReport.com and you can use a free tool like Credit.com’s credit report card to check for signs of identity theft every month.

It’s also a good idea to check with your insurance agent, bank, credit union or the HR department where you work. It is increasingly more common to be offered free access to a program that provides education, proactive assistance and damage control if you become a victim of identity theft.

If it’s not free, you may be able to get it at a minimal cost. (Full disclosure: CyberScout, a company I founded in 2003, provides these services to institutional clients, and they in turn offer the service to their clients, customers, members or employees.)
