Evidence-based answers — from why you get bitten more than your partner to where mosquito season is heading as species ranges shift.
Rain creates the water mosquitoes need to breed, but a new generation takes 7–14 days to emerge. The surge you feel isn't from the storm — it's from the last one.
You're not imagining it — twin studies show ~85% of bite susceptibility is genetic. CO₂ output, skin bacteria, blood type, and body heat all play measurable roles.
Ae. aegypti is now established in 20+ California counties. The tiger mosquito has reached 40 states. Warmer winters are redrawing the map faster than control programs can track.
Both are EPA-registered and both work. The real differences are in feel, duration, and what you're protecting against — plus when to add Permethrin on top of either.

The Gulf Coast's dengue and Zika vector — a daytime biter that breeds in the clean water containers around your home. Established year-round in South Florida, coastal Texas, and now spreading into California.
