Small Red Spiders in House: Easy Solutions for Homeowners: 1 Minute to Identify and Get Rid of Small Red Spiders Indoors

Small red spiders appearing in your house can be startling, but they’re a common issue for many homeowners. These tiny creatures are often clover mites or red spider mites, both are harmless to humans but unsightly when they crawl around baseboards, windowsills, and walls. Understanding their behavior and how to manage them helps you keep your home clean and pest-free.

What are small red spiders? Most "small red spiders" found indoors are actually clover mites. They measure about 0.75mm and move quickly, preferring bright, sunny locations. Red spider mites, on the other hand, tend to infest houseplants and greenery rather than the walls or floors.

Why do they enter houses? Clover mites usually invade in large numbers during spring or fall when outdoor conditions change. Their tiny size means they easily slip through cracks or gaps in windows, doors, and foundations.

Easy Solutions to Manage Small Red Spiders

1. Seal Entry Points: Inspect your home’s exterior, especially near windows and foundations. Use caulk to seal cracks or gaps that might serve as entryways.

2. Vacuum Regularly: If mites are already indoors, use a vacuum attachment to remove them gently without squashing them, as the stains can be hard to clean.

3. Remove Attractants: These mites feed on grasses and plants. Trim landscaping back from your house and avoid over-fertilization, which attracts them.

4. Limit Moisture: Spiders and mites prefer moist environments. Use dehumidifiers and ensure rooms are well ventilated.

5. Natural Deterrents: Sprinkle diatomaceous earth where they're most visible. This powdery substance harms pests without using chemicals.

6. Keep Houseplants Clean: Regularly inspect and clean houseplants to prevent red spider mite infestations, which can quickly spread indoors.

As an interior designer, I often notice that clients encounter these pests during or after home renovations. Redesigning entrances and windows with proper seals, or even updating flooring and wall materials, can inadvertently reduce pest issues by eliminating access points. If you’re planning updates, using a professional home designer tool helps visualize where vulnerabilities might occur and allows you to build a healthier, cleaner home environment from the ground up.

Tips 1:

Have your landscaping trimmed at least 18 inches away from the house foundation. This creates a physical barrier that reduces the migration of clover mites and other small pests into your living space.
