Fleas can be found on pets year-round, but populations tend to increase dramatically in spring and summer when temperatures are warmer. Larvae develop rapidly in areas where temperatures reach 70° to 90°F. Fleas are a major concern for pet owners as they can give dogs and cats tapeworms, but they can also transmit flea-borne typhus to people and spread plague to wild animals like ground squirrels. These blood-sucking pests can be introduced to backyards from feral cats, squirrels, opossums, and other wildlife.

Backyard chickens are increasingly being raised as pets, for egg production, and for youth development and science projects. While raising chickens can be an interesting and economically beneficial activity, chickens and other fowl may also have pest problems. Chickens are natural hosts to a variety of arthropod pests (called ectoparasites), including mites, lice, and fleas which feed on chickens and use chicken coops as habitats. These pests may cause discomfort to birds and decrease their egg production. This article aims to help people who keep chickens understand and learn treatment options for the common ectoparasites that can affect their animals.

Spring has arrived and with many Californians at home due to local coronavirus directives, now could be an opportune time for some spring cleaning. This annual ritual also has the benefit of preventing and reducing indoor pests.
Cleaning and decluttering removes access to food, water, and shelter for pests such as ants, cockroaches, pantry pests, mice, and
Opossums are the only marsupial native to North America and are quite interesting animals. Female marsupials may be seen carrying their young in an abdominal pouch or sometimes on their back. But opossums can also be pests.
This nocturnal animal can be a nuisance in neighborhoods when they dig through trash cans, compost piles, or food dishes intended for pets. If opossums visit your property occasionally, this may not be a cause for concern, unless your pets remain outdoors at night. Opossums will fight with dogs or cats and can inflict serious injury.
Opossums are often hosts for dog and cat fleas, and may carry several diseases including tuberculosis, toxoplasmosis, trichomoniasis and Chagas...
