Pest Guides: Which Pests Spread Disease in Buffalo? A Plain Guide

Different pests put your health at risk in different ways. This guide lists the main ones in Buffalo, what each can spread and where to read more.

Rats and mice

Rodents can contaminate food and surfaces with droppings and urine and are linked to illnesses including salmonellosis, leptospirosis and rat bite fever. They also leave allergens. See our guide to diseases rats and mice spread.

Mosquitoes

Mosquitoes in New York can carry viruses such as West Nile virus. Most infections are mild, but some become serious. Removing standing water and treating resting areas lowers the risk.

Cockroaches

Roach allergens can trigger asthma, and roaches can carry bacteria onto food and surfaces. Apartments and restaurants need a program that reaches hidden harborage.

Fleas

Fleas bite people and pets, and cat fleas can carry the bacteria behind cat scratch disease and tapeworm larvae. They need treatment of both the pet and the home.

House flies and cluster flies

Flies carry bacteria on their bodies and legs and spread it to food, which is why they matter in kitchens and food businesses.

Bed bugs

Bed bugs are not known to spread disease, but their bites cause itching, loss of sleep and stress, and scratching can lead to skin infection. They are one of the hardest household pests to remove.

Yellow jackets, wasps and hornets

Their danger is the sting. People with venom allergies can have life threatening reactions, so nests near doors and play areas should be removed by a professional.

They are not known to spread disease, but their bites and the stress they cause are real health issues.
