Yes — mosquito dunks formulated with Bacillus thuringiensis israelensis (Bti) are considered safe for use in backyard ponds and fountains when applied according to label instructions, because Bti specifically targets the gut of mosquito and other dipteran larvae and has minimal toxicity to humans, pets, birds, and most fish and wildlife. These biological larvicides are…

Professionals locate hidden mosquito breeding sites by systematically inspecting potential water-holding microhabitats—both natural and artificial—using visual surveys, larval sampling (dipping), nighttime adult trapping, and evaluation of drainage and vegetation patterns. These combined techniques help identify cryptic sources such as clogged gutters, tree holes, underground culverts and catch basins, discarded containers, and intermittent depressions that collect…

The safest way to treat for mosquitoes around children and pets is to use an integrated approach that emphasizes removing breeding sites and physical barriers first, then applying low‑toxicity biological controls and targeted, label‑compliant products only when necessary. This matters in the Pacific Northwest because our mild, wet climate and abundant standing water—from backyard containers…

Mosquitoes reappear quickly after heavy summer rain because many local species lay eggs that either survive dry periods or are ready to hatch immediately when dry depressions and puddles refill, and warm post‑rain temperatures can speed immature development so adults emerge within days. Floodwater Aedes species deposit eggs on damp soil that remain viable until…

You can substantially reduce mosquitoes without spraying the whole yard by focusing control on breeding sources and resting sites—eliminating standing water, applying larvicides or biological controls directly to known water sources, and using barriers, traps, or localized adult treatments only where mosquitoes concentrate. Targeted measures interrupt the mosquito life cycle at its most productive points…

Mosquitoes are attracted to certain people more than others primarily because of differences in body odor, carbon dioxide output, skin temperature, and blood chemistry. Variations in skin microbiota produce different volatile compounds (like lactic acid and ammonia) that make some individuals more detectable; higher rates of carbon dioxide exhalation, elevated skin temperature, pregnancy, recent alcohol…

Mosquito misting systems keep yards bite-free by automatically dispersing fine, metered droplets of insecticide into the air and onto vegetation where adult mosquitoes rest and feed, producing rapid knockdown of adults and a short-term residual barrier around treated areas. These systems use timed or sensor-activated pumps and nozzles to create a uniform mist that contacts…

Mosquito bites commonly become more irritating in late summer because mosquito populations reach seasonal peaks and repeated exposure to salivary proteins primes stronger immune reactions, producing larger, itchier welts. When a mosquito feeds it injects a cocktail of proteins that prevent clotting and blunt local hemostasis; the body’s immune response—mediated by IgE/IgG antibodies, mast cell…

A handful of common garden plants — including citronella grass (Cymbopogon spp.), lavender (Lavandula spp.), lemon balm (Melissa officinalis), catnip (Nepeta cataria) and various mints — produce volatile compounds (citronellal, linalool, nepetalactone, menthol and related oils) that can reduce mosquito landings when planted or brushed against near outdoor seating. These botanical repellents work by masking…

To mosquito-proof a backyard before a summer party, eliminate standing water, reduce dense shaded vegetation where mosquitoes rest, increase air movement with fans, and apply targeted larval control or perimeter treatments as needed. These steps address both the breeding and resting habitats that support local mosquito populations and reduce the number of host-seeking adults during…
