Bed bug heat treatment: temperatures, methods, what actually works
Bed bugs and their eggs die at 50°C (122°F), instantly on direct contact, in minutes through fabric, in hours through dense materials. The four practical heat methods (chamber, dryer, steamer, whole-room professional) and where each is the right call.

DIY bed bug treatment without making it worse: sprays, home remedies, heat
Most off-the-shelf sprays match a water control in mortality (Rutgers experimental data). What goes wrong with DIY and how to do it right when you commit: the 8-step protocol from Wang Lab that actually works without an exterminator.

Washing bed bugs out of clothes: which temperature actually kills them?
60°C (140°F) works, if the load is half-full and the main cycle is long enough. The dryer is often more effective than the wash. What to do with wool, silk, function fabrics that can't take heat.

Freezing bed bugs: at what temperature and for how long?
−18°C (0°F) for 80 hours in a sealed bag, confirmed by Olson et al. 2013. Why a household freezer can do it but rarely does it well, and when freezing beats heat (electronics, books, vinyl).

Bed bugs in electronics: laptop, TV, game console, three rules for heat treatment
Electronics are warm and full of crevices, a favorite hideout. The three iron rules of heat treatment: remove batteries, never above the device's spec'd storage temp, no LCD displays in a chamber. Plus alternatives for sealed-battery gear.

Bed bug sniffer dogs: when they actually help (and what they cost)

Bed bug traps: interceptors, glue traps, CO₂ lures, what works
Four trap types compared. Bed-leg interceptors are by far the most useful, for monitoring and post-treatment verification, not for population control. What glue traps and CO₂ traps are good and bad for.

What works against bed bugs? Honest product comparison: sprays, dust, heat
Sprays, powders, home remedies, professional treatments, direct comparison with mortality data from Rutgers Lab experiments. What works (heat, food-grade DE), what doesn't (most sprays), what's outright dangerous.

Professional bed bug heat treatment: process, real costs, when it's worth it
The most reliable method for active infestations, but expensive and intrusive: why whole-room thermal remediation costs $1,500-4,000, the technical setup (industrial heaters, three-phase power, multi-day operation), and when the spend is justified.
