Cold-Weather Cockroach Control Strategies for Property Managers

Cockroaches are an issue for millions of homes across the United States, with apartments and multi-family dwellings at particularly high risk. Cockroach control in these settings is a real challenge for pest control professionals and property managers alike. Shared spaces and boundaries, varying commitment levels to sanitation and prevention standards, and multiple entry points increase the likelihood of cockroach activity, in general. 

Additionally, many tenants and property managers may not be aware of the increased risk of cockroach activity during cold weather months. These cold-intolerant pests scurry indoors to seek out warmth, food, and moisture, resulting in large numbers of pests moving in and taking up residence. 

Let’s explore the challenges property managers face during cold weather months and how they can minimize or prevent a full-scale infestation.

Why Cockroaches Move Indoors in Winter 

Unlike many birds that fly south and head to warmer climates for winter, cockroaches migrate indoors. Although the German cockroach, one of the most common in Upstate New York, lives its entire life indoors, American and Oriental cockroaches are known as peridomestic. These cockroaches can live both indoors and outside, although they will migrate inside once the weather necessitates it. 

Let’s explore this phenomenon in more detail and examine its significance for apartment buildings and multi-unit complexes. 

Biology and Environmental Triggers

Cockroaches are cold-blooded and don’t produce their own body heat. While this allows the insects to go for extended periods (up to a month) without food, it also leaves them vulnerable to their environment. German cockroaches, for example, are very cold-intolerant and will halt development in temperatures of 59 degrees Fahrenheit or below. Still, these cockroaches live near and around humans, making them a year-round problem.

American and Oriental cockroaches can also be a year-round problem, as these species can survive outdoors. Oriental cockroaches are somewhat more tolerant of cooler weather, surviving in temperatures as low as 40 to 45 degrees Fahrenheit. Along with American cockroaches, they typically move indoors once temperatures dip to 50 Fahrenheit. 

Cockroach Behaviors 

As far as behaviors go, each species is relatively similar in preferring warm, moist environments. Some of the differences include their preferred temperatures and where they like to hide. 

• German Cockroaches: Prefer temperatures ranging from 85 to 95 Fahrenheit and are commonly found in kitchens in hidden spots under appliances and inside cabinet voids
• American Cockroaches: Prefer temperatures of 70 to 80 Fahrenheit and are commonly found in sewers, steam tunnels, basements, and boiler rooms
• Oriental Cockroaches: Prefer milder temperatures around 75 Fahrenheit and are commonly found in moisture-rich spots such as crawlspaces, basements, garages, mulch piles, and around foundations

Operational Relevance for Apartment Buildings

When property managers understand the behaviors of these pests and the environmental triggers that send them scurrying indoors, it equips them with improved preventative strategies. For example, knowing that German cockroaches prefer to remain indoors helps professionals establish a year-round treatment program. At the same time, understanding that other species move indoors once temperatures dip below 50 Fahrenheit should help determine the timing for apartment pest control inspections and exclusion efforts. 

It’s also helpful to gain a deeper understanding of how cockroaches enter and spread through apartment buildings. Typical entry points include beneath doors, through gaps around utility penetrations, and inside shared infrastructure like pipes and wall voids.

Key Steps for Managing Cockroach Activity in Cold Weather 

Cockroaches are resourceful critters that are adept at hiding, which makes prevention and a solid management strategy essential. Floor drains, cracks narrower than a credit card’s width, and loose door thresholds are key entry points that offer easy access for pests. Implementing a robust preventative strategy that sets and outlines sanitation standards is an excellent starting point. 

Follow Effective Prevention Measures 

Prevention is the gold standard in helping to control cockroaches, and removing food and water sources can be incredibly effective in mitigating these pests. Routinely cleaning waste disposal areas, such as recycling bins and dumpsters, is a helpful starting point. Installing exclusion systems that seal off entry points is also important. Ensuring trash is regularly removed and establishing sanitation standards for all areas of the property is mission critical. 

Essential preventative steps to follow include the following:

• Seal cracks and gaps around utility penetrations, foundations and walls, doors and windows
• Install securely fitting screens on all windows and doors
• Add doors sweeps to close any gaps under doorways, both interior and exterior
• Make all necessary repairs promptly, including plumbing leaks
• Clean all common and shared areas regularly
• Establish minimum sanitation standards for residents
• Maintain landscaping by trimming any shrubbery or trees away from the exterior of the buildings
• Ensure any standing water or debris is removed promptly

Set Inspection Protocols

Regular inspections can help property managers and maintenance professionals stay ahead of cockroaches for more effective prevention. During inspections, look for signs of cockroach activity, such as dark specks of fecal matter, shed skin, and egg casings. Also keep a close eye out for any openings that cockroaches could use to enter the building or spread between spaces. Inspect common harborage sites, including the following:

• Building exteriors, including outside walls, underneath siding, bricks, and utility intrusions
• Garbage, recycling, and compost areas
• Landscaping, including under shrubs, in mulch and leaf piles, and in wood piles or tree holes
• Sewer vaults and lines, unused floor drains 
• Areas beneath buildings, including storage spaces, sub-basements, and crawlspaces
• Along roof lines, including overhangs, gutters, and soffits

Engage in Regular Tenant Communication

Prevention is a multi-pronged approach that requires tenants to cooperate, as well. Because of how easily cockroaches can spread across a building, each tenant must take responsibility for doing their part. It’s important to ensure everyone understands the signs of a potential infestation, how to report cockroach (and other pest) activity, and how they can help. Educate tenants on protocols such as:

• Proper food storage
• Importance of routine cleaning
• Checking all packages to ensure they don’t contain hitchhikers
• The need to reduce/eliminate clutter
• Following regular schedules for removing garbage
• How to report pest sightings or signs of an infestation 
• Providing access for scheduled pest control treatments and inspections
  

Winter Cockroach Trends Property Managers Should Monitor

Cockroaches present a year-round challenge in apartment buildings and multi-unit complexes. However, activity among species that move indoors during cold weather typically spikes once temperatures drop below 50 degrees Fahrenheit. Monitoring temperature anomalies, both early and late in the season, can equip property managers with the ability to stay ahead of cockroach activity. 

During winter, multi-family dwellings make an ideal shelter with numerous protected, warm areas for cockroaches to nest and scavenge for food. Warm spells can increase activity, and species that moved indoors for winter often begin to prepare to move back out during late winter and early spring. Increased sightings indicate the need for commercial winter pest control to ensure effective eradication before infestations grow out of control. 

Interpreting Inspection Findings

Inspections provide key data points that property managers can use to inform their prevention and abatement strategies. For instance, if an inspection shows signs of cockroach activity, managers can notify tenants and schedule professional treatment services. Signs may include droppings, which look similar to flecks of black pepper; musty odors; brown-colored, oblong-shaped egg casings; and live cockroaches. Likewise, inspections that show gaps, cracks, and areas of disrepair provide invaluable information managers can use to halt cockroaches from coming indoors. 

Remaining Aware of Trends Tied to Building Age, Insulation Gaps, and Occupancy Density

High population density in apartment buildings and complexes increase the risk of numerous pests, including cockroaches. More people mean more chances for tenants to inadvertently provide food and water to attract these pests. Buildings and complexes with high occupancy density must take stringent precautions and remain vigilant. 

Likewise, the age of the building(s) also has a direct bearing on the risk of cockroach infestations. As buildings age, plumbing systems can become leaky or begin to exhibit signs of condensation, providing hidden sources of water for moisture-loving pests. Additionally, older buildings also are more likely to have cracks, gaps, and openings as well as older appliances that collect grease and crumbs, two potential food sources. 

Finally, insulation gaps present a two-fold problem. They offer cockroaches a warm nesting spot and may make it easier for them to enter the property.

Benefits of Strengthened Winter Cockroach Protocols

Consider this: If the building was on fire, would it be better to douse the flames before they spread, or wait until they affected more than one unit? Cockroaches spread quickly, breed at a rapid rate, and can become a rampant issue with relative speed. The stronger the cockroach prevention protocols of an apartment complex in the winter, the more capable property managers are at minimizing issues.

In turn, preventative measures have the potential to offer multiple benefits, including a more positive tenant experience and reduced long-term costs. 

Happier, Safer Tenants

Cockroaches pose a serious safety risk. They can carry and transmit many germs and vectors of disease that can make tenants and employees ill upon exposure, including E. coli, dysentery, and salmonella. New York State and Western Massachusetts have habitability laws and regulations requiring landlords and property managers to provide safe, clean, pest-free environments. 

Strengthening winter cockroach protocols aids property managers in remaining compliant with local laws. Additionally, more satisfied tenants create a more harmonious environment overall, with fewer complaints to field.

Higher Occupancy Rates

Satisfied tenants tend to stay longer. When tenants trust in management teams to ensure safe, pest-free environments, it often leads to greater marketability, a better reputation, and higher overall occupancy rates. 

Financial Savings

Catching an infestation early typically results in lower costs. Many factors surrounding the cost of professional control are out of the hands of property managers, including the size and location of the building. However, the severity of the infestation is a major factor in determining costs. Additionally, with a robust preventative strategy and effective exclusion measures in place, long-term costs are likely to be significantly lower.

Comparing Winter Cockroach Prevention Methods

To be really effective, winter cockroach prevention needs a holistic approach that relies on a mix of proactive and reactive treatments. It also requires both professional pest control services and in-house control measures. 

Proactive vs. Reactive Cockroach Treatments

A proactive approach forms the bedrock of every effective control plan. It’s the foundation of integrated pest management (IPM), a highly effective strategy that aims to prevent and exclude pests to minimize the need for using chemicals. Regular monitoring, inspections, and preventative measures help reduce the odds of cockroaches infesting multi-unit dwellings during winter. Proactive cockroach control offers an eco-friendly, cost-efficient way to deal with these skittering pests. 

However, even the best measures do not offer an absolute guarantee. When cockroaches are able to slip inside, whether they stowed away inside a package or crawled in through a tiny opening, reactive treatments are necessary. Eliminating cockroaches as soon as possible is essential to prevent them from breeding and creating a widespread infestation. 

That said, reactive measures alone are not effective to control cockroaches. They should be reserved for instances of pest sightings and activity, with proactive strategies used on the front line of prevention and abatement.

Professional Pest Control vs. In-House Maintenance Responses

Professional pest control is a must for commercial properties. Experts understand the risks that multi-family dwellings face, and professionals must have the training needed to identify species and tailor treatments appropriately. Best of all, pros will partner with property managers to help ensure that prevention measures are as effective as possible. 

However, it’s equally critical that in-house maintenance teams understand how to respond to reports of cockroach activity. In-house staff are also best equipped to perform regular inspections, keep a watchful eye out for signs of infestations, and enforce preventative measures throughout the building. 

How Property Managers Can Implement a Winter Pest-Control Plan

With all of that in mind, property managers should assess their building’s risk profile and create an inspection schedule accordingly. Although inspections are necessary before a tenant moves in and after they move out, performing routine inspections of the building and common areas is also critical. A single cockroach can produce up to 400 offspring in as little as three months. Scheduling monthly inspections, or at least inspections every three months by in-house staff, can help owners stay ahead of cockroach infestations as well as other maintenance issues.

Ready to get started in building a winter pest control plan? Try these steps to begin:

1. Create inspection checklists covering interior and exterior areas, including unit interiors, shared spaces, utility rooms, and the outside perimeter.
2. Inspect the property regularly, noting potential entry points and installing door sweep upgrades and sealing materials to keep cockroaches out. 
3. Install monitoring devices in sensitive areas, such as crawlspaces and mechanical rooms.
4. Implement sanitation protocols and educate tenants on their responsibilities.

Finally, partner with a trusted, reputable pest control company that can help with building-wide assessments, expert guidance, and preventative and reactive treatments.
