Common Pests In California


Bedbugs are small, reddish-brown insects that feed on human and animal blood. They are wingless and about the size of an apple seed. These pests are commonly found in beds and mattresses, and their bites can cause large, itchy welts that usually clear up within a week or two.


Rodents are mammals with a pair of continuously growing incisors in both jaws. They form the largest group of non-flying mammals, and their diets vary widely. Some species can spread diseases to humans.


Mosquitoes are common flying insects found in most parts of the world. The females of most species are known for their blood-sucking habits. While many mosquitoes are just nuisances, some can transmit serious diseases.


Wasps are insects known for their stinging ability. They come in social and solitary types, with social wasps building complex nests. While they can be a nuisance to humans, wasps also help control other pest populations by feeding on them.


Bees are insects with over 20,000 known species. They play a crucial role in pollination, helping plants reproduce. Some bees, like honeybees, live in large, social colonies that can survive for many years.


Cockroaches, the resilient creatures that have thrived for millions of years, are intriguing in their ancient origins. These medium-sized insects boast an unmistakable oval-shaped body, a characteristic shared across all species.


Spiders are fascinating arachnids belonging to the order Araneae, known for their unique ability to spin intricate webs. They are found all over the world, with over 45,000 species identified so far. While many people fear them due to their sometimes ominous appearance, most spiders are harmless to humans and play a vital role in maintaining the ecological balance by controlling insect populations.


Ants are small, industrious insects that belong to the family Formicidae. They are among the most prominent and successful insects on earth, with over 12,000 known species worldwide. Ants are unique for their advanced level of social organization, intricate communication systems, and diverse roles within the colony.

"Honorable, honest, efficient and provide fair pricing. Someone is always available to help and the tech's (Juan cares for our home), are also wonderfully adept. Sam, who I believe is the owner, is always incredibly kind, considerate, patient and informed. My husband is immune from mosquito bite reactions, although my daughter and I are not. We have NOT been bitten ONCE (at our home) since Facility began in the spring (and we have neighbors on either side of us with green, mossy pools). We are even able to enjoy sitting outside in the mornings and evenings now. So grateful we stumbled across this company! Highly recommend! A+++"
