The Ultimate Guide To Pest Proofing Your Home


Ultimate Guide to Pest-Proofing Your HomeMost people look forward to warm weather. Whether it’s soaking up the sun or having a backyard barbecue, when it’s warm outside, life is good. Unfortunately, pests feel the same about sunny days. Pests are constantly looking for a warm place where they can thrive…even your home!

Are you concerned about keeping your house pest-free?  Would you scream if you saw a rodent or a cockroach crawl across your kitchen floor?

The best way to prevent a pest problem in your home is to deny pests entry in the first place. We compiled this Ultimate Guide To Pest-Proofing Your Home to provide you with common-sense tips you can use to keep pests where they belong – outdoors! 

When the weather gets extremely hot or cold, pests will search for ways to enter your home in large numbers. You need to understand what attracts insects and rodents indoors in order to truly pest proof your home. Pests are just like humans, they need food, water, and shelter in order to survive. By eliminating the food source and their hiding spots, you eliminate the likelihood that these pests will make your home, their home.

Use these pointers to limit pest activity in your home!

Make Sure Your Doors Are Sealed

Ajar Door

Sealing your doors to keep pests out is similar to locking a door to keep an intruder out. But, if you examine your doors, you will probably be surprised by the amount of gaps that are available for pests to squeeze through. In order to combat these gaps, a door sweep can be installed under the door to cover the gap between the threshold and the actual door. In order to completely seal the door, you can add weather stripping around the door with chalk where it meets the door.

In addition to doors, it is also very important that garage doors are sealed as well. Many pests are able to fit through small openings in garage doors, so placing a door seal under the garage door will eliminate this entry point.

While these tips are very important to seal the entrances to your house, they will not be of much use if the door is kept open. If you or your children are particularly forgetful, you should consider installing an automatic door closer, which you can purchase at very inexpensive prices at most hardware stores.

Ensure That Your Windows Have Screens 

Broken Window Screen

During the warmer months, you likely open your windows to welcome in the fresh air. Unluckily, during these months, flying insects and crawling insects, such as mosquitoes and ants are abundant and ready to invade your home. To enjoy the fresh air without flying insects, it is crucial that you install screens in your windows and doors.

It is recommended that the screen size is 20 mesh or smaller to keep most pests out of your home. In addition to adding window screens, making sure window screens do not fall into disrepair is extremely important. Rodents can break through screens and allow additional pests to enter your home. If the wires become broken, an easy fix is to add clear nail polish to seal the hole in the screen.       

Maintain Your Yard


Most of the pests that can potentially enter your home come from your yard, especially pests that multiply exponentially such as mosquitoes. Since mosquitoes mostly breed in water, it is important that you eliminate any pooled or standing water. In addition, it is crucial that your drainage routes are clear and working and free of any leaves and sticks so that the water is able to drain properly. By eliminating leaves and sticks on your property, you will also be able to help eliminate harborage for pests.

Mowing your lawn and cutting down excess vegetation is also an important step in eliminating an ideal environment for their reproduction and habitation. Ticks and rodents thrive in conditions that are undisturbed like a yard that is not maintained or mowed.

Repair Cracks on the Exterior of Your Home


Any size crack or hole on the outside of your home can provide an entrance for ants, mice and host of other creepy crawlies. Begin by looking around your home very carefully and inspecting the exterior for any cracks in your foundation or siding that would allow pests entrance. To seal these spots it is best to remove the broken bricks and replace them with new ones while filling the gaps with mortar. It is also important to replace any rotting siding or trim as they are extremely susceptible to termite and carpenter ant damage.

Cover Openings on Home

Chimney Vent

Having a fire in your fireplace is extremely nice, especially on a cold winter day, but what people do not realize is that chimneys are also a great gateway for pests of all kinds to enter into your home. In order to cover the chimney vent, you can use a wire mesh that is fine and strong to keep everything out of the chimney, which can include squirrels and raccoons!

In addition to the chimney vents, most houses have crawl spaces that are seen as havens for pests of all sorts. To block these crawl spaces, you should also install wire mesh over the opening to prevent pests from coming in. Also, air conditioning units provide an excellent entry point into your home, so it is important that you remove them from your window when they are not in use.

Make Sure Food is for People Only


While it is great to imagine that you could perfectly pest proof your home, it is unlikely to make absolutely impossible for pests to get in. In order to make sure that these pests do not feel at home in your home, it is important that you eliminate their favorite things; food and water. If you are able to make sure that they do not have food and water or a place for them to hide, they will leave your house and go somewhere else where they can thrive.

Put food items in sealed containers after eating. This will help prevent spills which invite pests. If you do spill any foods or liquids, it is crucial that they are cleaned up right away with something as simple as a mixture of water and vinegar and a paper towel.

A very important tip for pest proofing, keep pet food stored properly so pests do not have access. Once your pet finishes eating, put their food and bowl away immediately afterwards. Insects like ants and cockroaches are especially fond of pet food.

Keeping Natural Predators to Pests Around


One of the best ways to make sure that pests are controlled outside is to ensure that there are natural predators to insects near your house. Birds, in particular, love to eat insects that could otherwise be infesting your home. Birds are great to welcome around your home by installing birdhouses in your backyard.

The Importance of Pest Proofing


Pests certainly are not something that you want in your home, so it is important to take the necessary precautions to prevent their entry. Aside from the general annoyance that pests provide, there are also more adverse effects.

Termites and carpenter ants have the ability to cause thousands of dollars of damage to your home due to their desire for wood. In the United States, termites cause an estimated 5 billion dollars in property damage. Diseases such as Lyme disease, dengue fever, salmonella and West Nile Virus  are also spread through pests, most notably through mosquitoes, ticks and rodents

Once pests infest an indoor space, it becomes a much harder task to eliminate them on your own. In these instances, we recommend contacting a professional pest control company like Ehrlich for assistance. Contact Ehrlich online today to have a technician conduct a free pest inspection of your property.

I joined Rentokil in June 2014 as a part of the marketing team as an intern in Reading, Pennsylvania. I am going to be a senior at Miami University in Oxford, Ohio as a marketing major. Ironically, I have a fear for pests, so I very much enjoy working for Rentokil. In my college home, I have had run-ins with raccoon's in my basement, bats in my bedroom and numerous rats scurrying about, so I have had some interesting experiences with home pest control!
