Discovering tiny, mottled beetles or fuzzy larvae in your home can be unsettling, especially when they’re munching on your favourite wool rug or silk curtains. Carpet beetles are common household pests that, while not harmful to humans, can cause significant damage to natural fibres like wool, silk, and animal hair. If left unchecked, an infestation can ruin carpets, clothing, and upholstery. This comprehensive guide will walk you through exactly how to get rid of carpet beetles, from identification to eradication and prevention, ensuring your home stays protected in 2026 and beyond.
To get rid of carpet beetles, start by identifying the infestation through larvae (fuzzy, striped) and adult beetles (small, oval). Vacuum thoroughly, steam clean at over 120°F (50°C), wash fabrics in hot water, apply boric acid or diatomaceous earth in crevices, and use insecticides if needed. Prevent future issues by storing natural-fibre items in airtight containers and maintaining regular deep cleaning.
Identifying Carpet Beetles: What to Look For
Before you can effectively tackle an infestation, you need to confirm that carpet beetles are the culprits. These pests come in two main forms: adults and larvae. Adult carpet beetles are small, oval-shaped insects, typically 2-5 mm long, with mottled patterns of white, brown, and yellow. They’re often found near windows or light sources, as they’re attracted to light. Larvae, on the other hand, are the real troublemakers—they’re fuzzy, striped, and about 4-5 mm long, feeding voraciously on natural fibres. Common signs of an infestation include:
- Holes in carpets, rugs, or clothing made from wool, silk, or fur.
- Shed larval skins in dark, undisturbed areas like under furniture or along baseboards.
- Adult beetles flying around windows or light fixtures.
- Damage to stored items in closets or attics.
Inspect areas like under beds, behind furniture, and in closets for these signs. If you’re dealing with other small pests, our guide on small black bugs in the house can help with identification.
Step-by-Step Guide to Eliminate Carpet Beetles
Once you’ve identified an infestation, follow these steps to get rid of carpet beetles effectively. This process combines cleaning, treatment, and prevention for long-term results.
- Find the Source: Thoroughly inspect your home, focusing on dark, hidden spots. Check under furniture, along baseboards, in closets, and around windows. Look for larvae, adults, and damage to fabrics.
- Vacuum Extensively: Use a vacuum cleaner with a HEPA filter to remove beetles, larvae, and eggs from carpets, rugs, upholstery, and crevices. Pay special attention to edges and under furniture. Immediately empty the vacuum bag or canister outside to prevent re-infestation.
- Steam Clean: Steam clean carpets, rugs, and upholstery at temperatures above 120°F (50°C) to kill eggs and larvae. This is a chemical-free method that penetrates deep into fibres.
- Wash Fabrics: Launder all affected clothing, curtains, and linens in hot water (at least 130°F or 54°C) and dry on high heat. For delicate items, consider professional cleaning.
- Apply Natural Treatments: Sprinkle boric acid or food-grade diatomaceous earth in cracks, crevices, and under furniture. These substances dehydrate and kill beetles without harsh chemicals.
- Use Insecticides if Necessary: If natural methods fail, apply specific indoor insecticides labeled for carpet beetles. Follow the manufacturer’s instructions carefully, and consider consulting a pest control professional for severe infestations.

Prevention Tips to Keep Carpet Beetles Away
Preventing carpet beetles is key to avoiding future infestations. Implement these strategies to protect your home:
- Store Natural-Fibre Items Properly: Keep wool, silk, fur, and feather items in airtight containers or sealed plastic bags. Avoid cardboard boxes, which beetles can chew through.
- Maintain Regular Cleaning: Vacuum and dust frequently, especially in hidden areas. A deep cleaning schedule can deter pests.
- Seal Entry Points: Check windows, doors, and vents for gaps where adult beetles might enter. Use caulk or weather stripping to seal them.
- Monitor High-Risk Areas: Regularly inspect attics, basements, and closets for signs of beetles. Early detection makes removal easier.
- Use Natural Repellents: Consider cedar blocks or lavender sachets in storage areas, as these scents can repel beetles.
