10 Houseplant Pests, Treated the Right Way
If you've ever treated a pest problem, felt like it was gone, and watched it come back two weeks later — this series is for you. Over 10 days, we broke down the biology behind 10 of the most common houseplant pests: what their lifecycle actually looks like, why one spray is never enough, and the exact treatment schedules that work.
The core principle behind every post in this series: pest control is contact sport. Most treatments work on contact only — they don't leave residue, they don't poison eggs, and they don't prevent reinfestation. What clears a pest is consistency: treating on a schedule that's faster than their reproductive cycle, until every generation is accounted for.

The One Rule That Ties It All Together
Every pest in this series has a lifecycle measured in days — not weeks. Fungus gnats complete a generation in 17 days. Spider mites can do it in 5 days in summer heat. Aphids reproduce without mating and can produce 80 offspring per week. The moment you stop treating, survivors rebuild. That's not bad luck — it's biology.
The fix is simple but requires discipline: treat on a schedule that's faster than the pest's reproductive cycle, and keep going for the full recommended duration even when you can't see them anymore. The posts in this series give you those exact schedules, pest by pest.
