Cold Winter Conditions May Lead to Increased Rodent and Insect Activity

While Southern Marylanders enjoyed the promise of warmer weather after a colder-than-usual winter, pest experts are warning that those chilly months may have inadvertently created the perfect breeding ground for a summer surge in unwanted guests. Our long, cold winter may lead to a more intense pest season than usual.

People often assume that freezing winters kill off pests, but it’s not that simple. In many cases, the cold actually drives pests deeper into our homes, barns, and crawlspaces, where they stay safe, warm, and well-fed. Once they’re in, they don’t just survive – they thrive.

Maryland’s recent winter brought temperatures well below seasonal averages and significant snow cover. This seemingly harsh weather, paradoxically, created ideal conditions for many pests. Snow acts like a thermal blanket. It might feel brutal outside, but under a foot of snow, rodents and insects are actually protected. The cold above insulates the warmth below, especially near homes where heat leaks into the foundation. This gives pests the perfect cover to nest and breed.

This protective environment means that many pests that overwintered successfully are now poised for a significant population boom as temperatures rise.

Pests to Watch For This Summer in Southern MD

Homeowners in Southern Maryland should be particularly vigilant for the following pests this summer:

• Rodents: Especially mice and roof rats, which found easy shelter indoors during the long winter and are now ready to expand their populations.
• Ants: These common invaders will begin foraging aggressively as outdoor food sources dry up in late summer, often seeking new supplies indoors.
• Earwigs and Spiders: Often driven indoors by hot, dry ground conditions, seeking moisture and shelter.
• Wasps and Yellowjackets: These stinging insects build up their numbers steadily throughout the spring and become more aggressive and noticeable by August.
• Even insects like mosquitoes may rebound quickly, thanks to rapid breeding cycles in favorable conditions.
  
  

What Southern Maryland Homeowners Can Do Now

Given the expert warning, preparation is key, and it starts early. Don't wait until you're overwhelmed!

• Seal Up Entry Points: Mice can squeeze through gaps the size of a dime. Walk the perimeter of your home and seal cracks, gaps in siding, and holes around utility lines. Use steel wool or copper mesh for rodent-prone areas. This is critical for keeping out not just rodents, but also many insects.
• Clean Up Outdoor Attractants: Don’t give pests a reason to stop by. Trim shrubs back from your siding, keep firewood off the ground, and clean up pet food or birdseed. Rodents and insects follow food trails. Ensure trash cans have tight-fitting lids.
• Watch for Early Signs: Droppings, gnawed wires, or faint scratching in the walls can all be signs that pests are already inside. By the time you see a rodent, there are likely more you don’t see. For insects, look for increased sightings, trails, or webbing.
• Act Sooner, Not Later: The biggest mistake people make is waiting until July when they're overwhelmed. If you suspect activity now – even if it’s just a few ants – it’s better to investigate or call in a professional early. Early intervention can save you significant headaches and expense down the line.
  
  

Rural and Urban Areas Alike Are at Risk

It's easy to assume that rural properties might be more vulnerable, but urban and suburban homes in Southern Maryland are just as likely to be affected. Rodents don’t care if you're in downtown or out in the country. Anywhere with warmth, water, and a little food can become a nest site. Pests can burrow into insulation, crawl into garages, or even settle behind kitchen appliances. Apartment buildings and multi-unit housing present their own challenges, with pests often moving between units through wall cavities or shared plumbing lines.
