Seal the Cracks to Keep Pests Out

Puerto Rico sure has its share of pests.

From mosquitoes to centipedes to spiders to scorpions, there are plenty of pests just waiting to climb and crawl into your home.

That’s why it’s a good idea to seal the cracks.

Cracks in your home’s foundation, in screens, around windows, and in the walls are like welcome mats for insects, bats, and other unwelcome guests. They make it easy for them to enter, make themselves at home, and reproduce.

You can prevent an infestation by following these three steps from Puerto Rico pest control experts for sealing cracks and keeping pests out:

1) Start with an Inspection

The first step to sealing cracks is to find them. Start by methodically making your way around your home—inside and out.

On the outside, look for cracks in the foundation, exterior walls, and any utility entry like where electrical or water lines enter your home. Inside, take a close look at all of your window and door screens, window frames, and kick plates attached to doors.

If you see any cracks, holes, or openings that are larger than a quarter inch, they need to be sealed. In fact, some insects can get into your home through a crack as narrow as the side of a credit card. So make sure you’re looking closely for cracks during the inspection.

You’ll also want to make sure you have some brightly colored tape with you to mark any trouble spots you find. This will make it easier to find them when it’s time to seal them up.

2) Look Up

After you’ve inspected the walls, windows, screens, doors, and frames, it’s time to look at your roof.

Many people overlook their roofs when they’re trying to pest-proof their home, but Puerto Rico pest control experts know that cracks in roofing materials, ventilation fixtures, and areas around pipes provide ample opportunities for pests to make their way into your home.

Don’t forget to check the caulking around exhaust vents, around roof-mounted air conditioning units, and under roof overhangs. All of these areas are susceptible to rotting and cracking.

So if you are serious about sealing cracks, don’t forget to look up.

3) Seal It Up

Now that you know how the pests are getting into your home, it’s time to seal it up.

There are many products available to seal the cracks, crevices, and voids through which pests are entering your home. Mesh screen covers work well for sealing exhaust holes under roof overhangs. Torn or ripped window screens will likely need to be replaced. So will cracked, missing, or rotting roof materials.

For cracks in plaster, bricks, stonework, or mortar joints, caulk is probably your best bet.

6 Pests You Should Expect to See This Year and How to Combat Them

No one likes the thought of having pests in their homes, no matter how tiny they may be. Having a home pest control service visit your home regularly is one of the best ways to keep pests in check and avoid an infestation that can be hazardous to both your family and the house itself. Here are a few of the most common pests we come across in Puerto Rico throughout the year and what you can do to protect yourself from them:


Termites are incredibly invasive and can cause serious damage to your home and furniture as they eat through the wood. They are notoriously difficult to get rid of and are found most often during the spring and summer months. The best way to combat these destructive creatures is to catch the infestation as early as possible. Watch for any damage to your walls, ceilings, floors, and furniture, including warping, sagging, or buckling, as these can be signs of termites burrowing underneath.


Like termites, moths feed on the wood found in and around your home and are most commonly found during the spring when the weather is humid. Just a few breeding moths can multiply into a colony of thousands, so aim to catch the problem as quickly as possible. The best way to get rid of a moth infestation is through tenting and fumigating your home to ensure that they are eradicated.


In addition to leaving itchy bites on your skin, mosquitoes can carry infectious diseases, like the Zika virus. Luckily, there are a number of ways you can protect yourself. Be sure to install screens on all of your windows, and keep doors closed except when entering or exiting your home. Eliminate any areas that have standing water, like underneath leaky faucets, in old trashcans, or in hanging tarps, as these areas tend to attract mosquitoes.


Unfortunately for Puerto Rican homeowners, rodents can be a problem throughout the year. These creatures, including rats and mice, can get into the insulation of your home and gnaw on electrical wires, causing significant damage. Try not to leave out any food that might attract them, and listen at night for any sounds of rodents living in your walls or ceilings. Traps can often be your best option to capture and get rid of rodents humanely.

Fleas and Ticks

Fleas and ticks can be hazardous to your family and your pets. These pests can carry infectious diseases, which they can pass on to those they bite. Be sure to check your children and pets for ticks regularly so that you can remove them as quickly as possible. With fleas, watch for bites, particularly on the lower legs.


Although bedbugs do not carry diseases like other biting insects, their bites can cause a severe reaction in many people, so it is best to get rid of them quickly. To protect yourself from these critters, be sure to thoroughly check your hotel rooms for them whenever you travel. If you have any doubts, request a different room or move to another hotel.
