How Climate Change Affects Local Pest Populations in CT
Connecticut has always had its fair share of pest problems, but in recent years, many homeowners and businesses are noticing a shift: pests are showing up earlier in the season, staying longer, and spreading into new areas. What’s behind the change? One major factor is climate change—and it’s having a bigger impact on local pest populations than you might think.
Warmer Winters Mean More Survivors
In the past, cold New England winters kept many pest populations in check. Deep freezes would naturally kill off large numbers of ticks, mosquitoes, and even some rodent species. But as winters become milder and shorter, more pests are surviving into the spring. This gives them a head start on breeding and increases their numbers dramatically.
At ProSource Pest Solutions, we’ve seen this firsthand. Tick and mosquito activity is now starting earlier than ever, and rodent infestations are no longer just a fall and winter problem. Without a hard freeze, pests have fewer obstacles to population growth.
Extended Seasons Equal More Generations
A longer warm season doesn’t just mean pests are around longer—it means they can reproduce more. Mosquitoes, for example, can produce multiple generations in a single season. When that season starts earlier and ends later, each generation adds to the problem.
Termites are also affected. With more time to forage and fewer cold snaps to disrupt their activity, colonies grow faster and spread more aggressively. That’s why ProSource Pest Solutions always recommends year-round monitoring and protection, especially in areas like Southington, Cheshire, and West Hartford where termite issues are becoming more common.
Shifting Ranges and New Threats
Climate change isn’t just affecting how long pests are active—it’s changing where they can live. Warmer temperatures allow pests like the black-legged tick (commonly known as the deer tick) to expand into areas of Connecticut where they were once uncommon. This brings with it a rise in Lyme disease risk and other tick-borne illnesses.
We’re also seeing increased calls for wildlife control. Raccoons, bats, and squirrels are becoming more active during what used to be off-season months, largely because food sources are more abundant due to climate shifts. At ProSource Pest Solutions, we’ve adjusted our wildlife service availability to meet these growing needs—especially during peak bat season.
What Homeowners Can Do
Now more than ever, consistent pest control is a necessity, not a luxury. Seasonal treatments help reduce pest populations before they spike, while year-round services keep homes and properties protected as weather patterns shift.
Connecticut residents should also stay informed. Be aware of any new pest threats emerging in your area and know that your usual seasonal timelines may no longer apply. The team at ProSource Pest Solutions is always available to help you identify risk factors and tailor a pest control plan that makes sense for your property and your family’s needs.
