Ants: The number one pest in Marin and Sonoma Counties. The Argentine ants are all the same size except the queen. Ants are social insects. They have multiple nests, and nest in potted plants, inside walls, and under concrete. In the West County hills the Carpenter ant will excavate tunnels in the wood of your house like termites. They prefer dead, damp wood in which to build nests. They do not eat it however, unlike termites. They usually nest in attics and on stumps near your home. They come in on power lines, sewer lines, etc. On both the Ant species you have to find the nest and eradicate the queen.
Spiders: Sonoma and Marin County has the largest population of spiders in California. They did a count in the 1990's and Sonoma averaged 2000 spiders per acre. While the venom of a few species is dangerous to humans, their webs are a nuisance and they can inflict painful bites.
Cockroaches: Usually brought in from bags from the grocery store. They hide and fit into very small cracks and crevices to evade humans but once established in the home they can multiply very quickly. They hide in kitchen and bathrooms and can spread germs and make allergies worse. They particularly like starch, sugary foods, grease and meats. In certain situations where there is a shortage of foodstuffs, they may eat household items such as soap, glue and toothpaste.
Rodents: Rodents multiply quickly. They have to chew from the time they are born until they die because their teeth are always growing. They eat through electrical wires in the house and cars, which can cause fire hazards.
Fleas: Fleas are external parasites, living off the blood of humans and animals. One flea after a blood meal can lay up to 400 eggs and reproduce every 30 days. They can be very dangerous and sometimes deadly to small animals.
Ticks: They have a very complicated blood-meal system and Deer ticks can carry Lyme disease. They usually lay between 1000-5000 eggs.
Flies: They can transmit dangerous diseases; we can help you control them.
Pantry pest: They include both moth and beetles. They infest milled products, flour, paprika, and grains. The larva usually does the damage.
Silverfish: They usually live in high humidity areas. They love starch and will eat through paper products and wall paper. You can find them in shake roofs, books, boxes, under ground, etc.
Wasps/Bees: They are very protective of their nests and will defend against invaders with a painful sting or bite.
Birds: Pigeons and barn swallows often like to make your home theirs. Their nests and excrement make quite a mess and can pose a health risk.
