Mosquito Control
for
La Pine, Oregon
Bti (Bacillus thuringiensis israelensis) and Bs (Bacillus sphaericus) are naturally occurring soil bacteria used as biological larvicides.
Why They Are Better:
Targets Mosquitoes at the Source
Bti and Bs specifically kill mosquito larvae in standing water before they become flying adults. This stops the next generation.
Extremely Selective
These larvicides only affect mosquito, blackfly, and fungus gnat larvae. They do not harm fish, birds, mammals, beneficial insects like bees, or other wildlife.
Environmentally Safe
Bti and Bs break down quickly in the environment and do not accumulate in soil or water. They are approved for use even in sensitive habitats and drinking water sources.
Long-Lasting Options
Some formulations (like Bti pellets or Bs briquettes) provide extended protection—weeks to months—keeping breeding sites under control with fewer treatments.
More Effective Over Time
By controlling mosquito populations before they hatch, larviciding reduces the total number of mosquitoes in the area, lessening the need for frequent fogging.
- Kills adult mosquitoes on contact but has no lasting effect.
- Only targets the mosquitoes present at the moment of fogging.
- Must be repeated frequently.
- Can affect other flying insects (non-target species).
- Requires more chemical volume over time.
Fogging has its place, especially when mosquito numbers spike and immediate relief is needed. But it’s like mowing the grass—it keeps coming back if you don’t deal with the root problem.
More Effective. More Targeted. Better for the Environment.
When it comes to mosquito control, not all methods are equal. While fogging (adulticiding) is what most people are familiar with, it’s actually the least efficient and most chemically intensive part of mosquito control.

Why Larvicides Like Bti and Bs Are the Smarter Choice
Fogging: A Temporary, Reactive Tool
Using Bti, Bs, and similar tools:
Reduces the need for repeated fogging
Minimizes pesticide use overall
Provides more consistent and long-term mosquito control
Protects non-target species and ecosystems
It’s a proactive, sustainable approach that benefits both the community and the environment.
