6 Best Laundry Detergent Additives For Sanitizing Infested Bedding

Coming home from a long backcountry trek should be a relief, not the start of a battle against hitchhiking pests that might have crawled into a sleeping bag. Bedding and camping gear are often overlooked during the post-trip decontamination process, allowing unwanted organisms to thrive in dark, warm environments. Taking a proactive approach to sanitizing gear keeps your equipment reliable and your home free from unwelcome intruders.

Lysol Laundry Sanitizer: Best Overall Choice

Lysol Laundry Sanitizer functions as an additive that kills 99.9% of bacteria that traditional detergents often miss. Unlike bleach, it is color-safe, making it ideal for high-tech synthetic fabrics found in modern sleeping bags and thermal base layers. It does not replace detergent but acts as an essential secondary step in the rinse cycle to ensure a deep clean.

For those returning from a humid climate or a shared bunkhouse, this product is the gold standard for peace of mind. It effectively neutralizes odors while stripping away pathogens that survive standard cold-water wash cycles. If the goal is a reliable, easy-to-source solution for everyday gear maintenance, this is the clear choice.

20 Mule Team Borax: Best Natural Pest Control

Borax is a naturally occurring mineral compound that serves as a potent insecticide and deodorizer. When added to the wash, it creates an environment where pests like mites struggle to survive while also softening hard water to improve detergent performance. It is an affordable, bulk-friendly option for those who manage large amounts of gear throughout the season.

This additive is particularly useful for pre-treating gear that has been stored in a damp basement or garage for an extended period. Because it is a powder, it integrates well with hot water cycles to provide a deep, abrasive clean for heavy-duty items like canvas tents or cotton-blend bedding. Choose Borax if you prefer a non-toxic, mineral-based approach to pest suppression that pulls double duty as a cleaner.

OxiClean Versatile Stain Remover: Top Choice

OxiClean utilizes oxygen-based bleaching power to break down organic matter and residue left behind by pests. While its primary fame comes from stain removal, its ability to oxidize debris makes it highly effective at sanitizing textiles without damaging technical membranes. It works by releasing oxygen bubbles that lift contaminants from the tight weaves of nylon and polyester.

This product excels at cleaning gear that has seen heavy, multi-day use where sweat and outdoor oils have built up on the fabric. It provides a thorough refresh for sleeping bags that have lost their loft due to accumulated grit. If the focus is on maintaining the longevity of high-end gear while ensuring it stays sanitary, OxiClean is the essential addition to the laundry room.

Hygea Natural Exterminator: Best for Bed Bugs

Hygea Natural is formulated specifically to target bed bugs and their eggs, making it a targeted solution for gear exposed to questionable lodging environments. It serves as a potent laundry additive that disrupts the life cycle of pests that commonly hide in the seams of sleeping pads and sleeping bag hoods. Unlike generic cleaners, this product is engineered to be aggressive against hard-to-kill insects.

Use this when returning from travel in areas with high infestation reports or after staying in hostels where gear might have touched infested mattresses. It is a specialized tool, not an everyday cleaner, designed for high-stakes sanitization. If the objective is absolute eradication of suspected infestations, this is the most reliable specialized additive available.

Kleen Free Naturally: Best Enzyme Treatment

Kleen Free Naturally uses a concentrated enzyme formula to break down the biological structure of pests and their waste. Enzymes act as biological catalysts, effectively digesting the debris that allows pests to colonize gear seams and zippers. This approach is highly effective because it treats the issue at a chemical level rather than just masking symptoms.

This additive is perfect for those who want a biodegradable option that remains tough on deep-seated contamination. Because it is enzymatic, it continues to work on residue even after the wash cycle ends. For adventurers concerned about the environmental impact of their cleaning agents while maintaining maximum efficacy, this product is the superior choice.

Premo Guard Bed Bug & Mite Additive: Top Buy

Premo Guard is a concentrated solution designed for rapid pest elimination without leaving behind harsh chemical smells or residues. It is safe for use on virtually any fabric, including down-filled sleeping bags and synthetic insulating layers. It functions as a preventative barrier that ensures any stray mites are neutralized before they can migrate to other parts of your living space.

This product is the right fit for the adventurer who demands a high-performance solution that respects fabric integrity. It is especially useful for treating gear after a thru-hike where equipment has been exposed to various environments for weeks at a time. If you prioritize gear protection alongside effective pest control, Premo Guard offers the most balanced performance.

What to Look for in Pest Sanitizing Additives

When selecting a laundry additive, prioritize formulas that specify “sanitizing” or “pest elimination” rather than simple “disinfecting” or “deodorizing.” Effective additives should be compatible with the specific materials of your gear, such as Gore-Tex, down feathers, or synthetic insulation. Always check for pH neutrality to ensure the chemicals do not degrade the DWR (Durable Water Repellent) coatings on your outer shells.

Concentration levels and rinse requirements are also critical, as residue can reduce the breathability of technical fabrics. Look for products that clearly state they can be used with high-efficiency machines if you are washing bulky sleeping bags at home. Ultimately, the best additive is one that kills the target organisms without forcing a complete re-treatment of your gear’s waterproof properties.

Why High Water Temperatures Matter for Bedding

Heat is the primary factor in sanitizing gear because it denatures the proteins in pests and their eggs. While many technical fabrics come with “cold wash” instructions, most sleeping bags and synthetic bedding can handle 140°F (60°C) for short, controlled periods during a sanitizing cycle. Using the hottest water permitted by the manufacturer’s care tag is the most effective, non-chemical way to eliminate hitchhikers.

If your gear cannot handle high temperatures, the sanitizing additive becomes your primary line of defense. In such cases, opt for a long, soaking cycle to allow the chemical agents to penetrate the insulation and fabric weave. Never skip the hot rinse or a high-heat drying cycle if the materials allow, as the combination of chemistry and heat is far more effective than either method alone.

Safely Treating Sleeping Bags and Travel Gear

Always start by shaking out your gear outside, focusing on zippers, velcro, and fold-over seams where pests congregate. Use a soft-bristled brush to sweep out grit and debris before the gear enters the washing machine. This prevents the machine from becoming a hub for contamination and ensures the additive works directly on the fabric surfaces.

Avoid overcrowding the washing machine, as bulky items like sleeping bags need room to circulate and absorb the sanitizing solution. If you are washing a down bag, use specialized down detergent alongside the sanitizing additive to maintain the feathers’ loft. Always complete the process with a full cycle in the dryer, as the mechanical action of tumbling helps dislodge any remaining debris.

How to Prevent Infestations on Future Travels

Prevention begins with storage; never leave your pack or sleeping bag directly on a hotel bed or on the floor. Use luggage racks or keep your gear in its waterproof stuff sack until you are ready to use it. When returning home, isolate your travel gear in a sealed plastic bin in the garage rather than bringing it immediately into the bedroom or closet.

Consistency in your post-trip routine prevents small issues from becoming home-wide infestations. If you travel frequently, designate specific sets of gear for backcountry use and keep them stored away from your indoor bedding. By treating your gear with the same level of care as your outdoor skills, you ensure your equipment stays ready for the next adventure without becoming a source of stress.

Proper sanitization is the final, essential step of any trip. By incorporating these additives into your post-adventure routine, you protect your investment in gear and keep your focus on the trail ahead. Keep your kit clean, stay prepared, and get back out there.
