How to mosquito-proof your yard
San Diego County says invasive Aedes mosquitoes bite during the day and will breed in as little as 1/4 inch of standing water, including indoor containers. Dumping or treating that water is the control the County lists first. Adult spraying does not replace that source work.
What you'll learn
- That County Vector Control describes invasive Aedes as day-biting ankle biters that breed in small containers
- The backyard water sources the County lists, including saucers, bromeliads, toys, and hidden containers
- When County and EPA say a bacterial larvicide such as Bti can treat water you cannot dump, if you follow the product label
- That County says eggs can sit dry for months and that biting often means a nearby source, without a 100-yard rule

How to identify bed bugs early
UC IPM says you confirm bed bugs by finding the insects or their signs, not by bites alone. The first places to check are mattress seams, box springs, bed frames, and nearby cracks, and to compare what you find with a reliable identification guide.
How to seal common rodent entry points
San Diego County Vector Control says trapping is only part of the work: seal gaps, remove food, and keep vegetation off the roof line. CDC and UC IPM both treat exclusion as the lasting control. Check what you can see from the ground first.
How to prevent ants in your kitchen
UC IPM says the Argentine ant is the most common household ant in California. Most ants live outdoors, so the lasting work is sealing entry, removing food and water, and baiting the colony rather than spraying indoor trails.
