Maryland Pest Problems

The worst pests in Maryland, spiders and mice, can be terrifying to discover in your home. There’s a good reason they inspire fear because these invaders can be dangerous. 

Maryland has 32 different species of spiders, including the poisonous Black Widow and Brown Recluse. Spiders are a common crawl space pest, and many species like the damp, dark environment of the ground floor before moving to the upper levels of your home. 

Rodents are a problem throughout the state, and their ability to carry diseases can make them dangerous to your health. In recent years, there has been some feuding between the cities of Baltimore and Washington D.C. as to which city has a worse rodent problem. According to the 2020 data from Orkin, D.C. is worse, ranking as the fourth “rattiest” in the country, compared to Baltimore’s ranking of eighth in the country. However, with both cities ranking in the top 10, it’s clear that rodents are a problem throughout the area. 

In Baltimore, finding rodents at home has been more of a problem during the pandemic. As potential food sources for pests shifted from restaurants to backyard barbecues, rodent populations have moved from commercial districts to people’s homes. 

Will Cicadas Become the Worst Maryland Pest in 2021?

The pest population in Maryland is about to change dramatically. When the ground eight inches below the surface reaches 64 degrees (likely in early May), billions of cicadas will emerge from the soil. 

“Maryland is at the epicenter, and this is one of the largest [cicada] broods that occurs at one time in 15 different states across the eastern United States,” explains a UMD entomology graduate student. 

After this 17-year Brood X emerges, we expect that cicadas will shoot to the top of the list of the worst home pests in Maryland. 

Cicadas generally won’t cause much damage to your home or landscape, although some young trees could be at risk. They won’t sting or bite, but they’re very noisy, using sound to communicate and attract a mate. A high density of cicadas can get as loud as 100 decibels, and the sound can last for the eight weeks that the insects are expected to be above ground. 

A high-density area of cicadas can have as many as one million insects per acre. Maryland residents should prepare for a lot of bugs and a lot of cast skins after they molt.

What About Termites in Maryland?

Maryland has a high risk for termites, and Baltimore ranked as the 15th worst city in the country for termites, according to Orkin. 

A key problem for homeowners in the state is that termites rarely infest dry wood. Water problems are usually the precursor to termite problems, and Maryland has a massive shoreline, heavy rains, and prevalence of flooding.

Termites can cause significant damage to homes. A colony can eat about a pound of wood per day and go undetected for years. When the termite problem is finally found, the wooden beams of your house could be so perforated inside that they look like corrugated cardboard. 

For example, Maryland residents near Baltimore discovered termite damage after they bought what they thought was a perfect starter home. During the sale, they learned that the basement floods during heavy rain. Later they discovered this water likely brought about the termite infestation. The damage is so bad that the new owners expect repairs to cost about half of what they spent to buy the home.

What Structural Solutions Can Help You Reduce Pests?

Pest control and extermination are important first steps to managing pest problems. However, you’ll never get a pest problem under control if you don’t deal with the structural problems of how they got in or why they want to be there. Here’s how the structure of your home plays a role in pest control, and what you can do to make it more difficult for pests to get inside your house:

1. Seal the cracks and gaps where pests are entering. One of the best things you can do is to prevent pests from getting into your home in the first place. It’s especially important to look along the base of your home where burrowing pests can use foundation cracks as an easy entryway. 

2. Make your home less inviting to pests. Many pests are attracted to damp conditions around your home or a damp basement or crawl space. Basement waterproofing can make your home less attractive to pest invaders and more enjoyable for you. You can add interior drainage, sump pumps, and dehumidifiers. If your home has a crawl space, a thick, durable vapor barrier can make it hard for pests to get inside your home. 

3. Integrate termite protection into your structure. Many new homes use materials that have integrated termite protection, and homeowners who are making repairs can get the same benefit. For example, adding insulation panels to the lower level of your home creates a clean, dry area, and because it’s treated with termiticide, your home won’t have the same risks as it would with soft, wet insulation in the lower level of your home.
