Bug guides specific to the bathroom.
A tub or a basin is a pitfall trap you did not mean to set: springtails fall in from a damp joint above and cannot climb the glazed wall back out. The drain is almost never the way in.
Springtails in a bathroom are not coming up the drain — they are living on one surface that never dries between showers. Finding that surface is the treatment, and this walks the six places it hides.
Four different bugs turn up in bathrooms for the same damp reasons. Size and behavior are enough to tell a silverfish, a drain fly, a booklouse, and a springtail apart.
Those quick, metallic-silver bugs showing up in the bathroom are almost certainly silverfish. Here's how to confirm it, plus where to go for the full profile and a bathroom-specific fix.
A wingless, near-black speck in the bathroom is almost always a springtail or a booklouse. The two look similar but move completely differently, and that's the tell.
No single bug in our catalog is a perfect match for "tiny, reddish-brown, in the bathroom." Here's how to narrow it down between the three real possibilities.
Simple moisture, ventilation, and drain habits that keep silverfish out of the bathroom.
Small flies near your houseplants and small flies near your drains are two different insects with two different fixes. This protocol shows you how to tell them apart, find the actual breeding site, and confirm the fix worked with sticky-trap monitoring.
Silverfish thrive on moisture, not sprays. This six-step protocol goes after the humidity that's actually feeding them, then clears out food sources and seals up the cracks so they don't come back.
