Multifamily Housing

Pest control in multifamily housing comes with a unique challenge: what happens under one roof rarely stays under one roof. Shared walls, utility lines, hallways, trash areas and resident traffic can provide pests with multiple routes to move between units and common areas. Without early intervention, even a small, isolated issue can develop into a property-wide infestation.

Effective pest management requires more than treating pests when they appear. Property owners and managers can use an effective Integrated Pest Management (IPM) program to ensure timely inspections, preventive maintenance, resident communication, documentation and targeted treatments if or when an issue arises.

Why Is Pest Control Important in Multifamily Housing?

Multifamily properties can be especially vulnerable because they contain numerous sources of food, water and shelter. Conditions inside one unit can contribute to pest activity in neighboring apartments.

Pest activity can damage property, disrupt operations, reduce resident satisfaction and affect health. However, the potential health risks of pests may not be widely understood. According to a National Pest Management Association (NPMA) survey conducted by the Harris Poll, only 39% of Americans are aware that cockroaches can spread diseases or allergens.

Recurring infestations can impact your business in the following ways:

• Resident complaints and negative online reviews.
• Increased service calls and maintenance costs.
• Delays in apartment turnover.
• Damage to wiring, insulation, walls and other materials.
• Exposure to bites, stings, allergens and pest-associated pathogens.
• Regulatory scrutiny or housing-code violations.
• Damage to the property’s reputation and resident retention.

Pests That Threaten Multifamily Properties

Cockroaches can spread between units through cracks, wall voids, plumbing and utility lines. They can also trigger allergies and asthma symptoms, especially in children. 

Rodents, such as mice or rats, enter through small openings and can contaminate food and surfaces while damaging wiring, insulation and other materials.

Bed bugs can spread through residents’ belongings, shared spaces and openings between neighboring units.

Ants often enter in search of food and water and may nest inside walls or around foundations.

Flies are commonly found near dumpsters, trash areas, drains and other sources of food and waste.

Termites can damage wood framing and other structural materials, often without obvious signs of activity.

What Should a Multifamily IPM Program Focus On?

• Check apartments, common areas and exterior spaces for early signs of pest activity.
• Accurate identification to help determine the right treatment.
• Address leaks, spills, waste and improper food storage.
• Close cracks, gaps and openings where pests can enter.
• Address moisture, clutter, drainage and landscaping issues.
• Work with a professional to choose treatments based on the pest and its activity.
• Encourage prompt reporting and steps to prevent reinfestation.
• Reinspect treated areas and adjust the approach as needed.

Why Work with a Pest Management Professional?

A qualified pest management professional can assess pest activity across an entire property rather than treating one apartment at a time. This is especially important for pests like cockroaches, rodents and bed bugs, which can spread rapidly.

Professionals can identify pests, find contributing issues, recommend targeted treatments, monitor results and help property teams prevent future infestations. They can also train staff to spot early warning signs and maintain effective treatment.
