Questions

Pest questions in Whittier

Why do I see so many ants in my Whittier kitchen?

Argentine ants are prevalent in Southern California and often enter homes in Whittier, especially when outdoor conditions are too dry or too wet. They are searching for water and food indoors. Sealing entry points and removing food sources can help, but large colonies may require professional treatment.

What kind of termites are common in Whittier homes?

Whittier homes can experience both drywood and subterranean termites. Drywood termites live entirely within the wood and are often found in attic rafters or door frames. Subterranean termites build colonies in the soil and require soil contact, often entering through foundation cracks. A wood-destroying pests and organisms inspection can identify the type.

Are the mosquitoes in Whittier a concern?

Yes, the invasive Aedes mosquito is active in Whittier and can transmit diseases. These mosquitoes are small, black and white, and bite during the day. They breed in very small amounts of standing water, making it important to regularly check and empty anything that can hold water around your property.

How can I prevent roof rats from getting into my Whittier attic?

To prevent roof rats, trim tree branches and ivy away from your roof, seal any openings larger than a quarter inch in your eaves and attic vents, and cap chimneys. Roof rats commonly use overhead routes like power lines and fences to access homes in Whittier and seek shelter in attics.
