How to Get Rid of Spiders

Spiders are a common part of the Kenyan landscape, but they become a significant concern when they invade your personal or professional space. While many see them as a minor nuisance, a growing spider infestation can lead to unsightly webs, psychological distress for those with arachnophobia, and potential health risks.

At Rentokil Kenya, we provide the educational resources and professional expertise you need to regain control of your environment.

Understanding why spiders choose your building is the first step in effective management. Spiders are primarily driven by three factors:

During the rainy seasons in Kenya, or as temperatures drop at night, spiders seek dry, undisturbed areas like ceiling cavities and storage rooms.

In certain seasons, male spiders become more active as they leave their hiding spots to find a mate, making them much more visible to inhabitants.

Spiders are predatory. If your property has a high population of flies, moths, ants, or mosquitoes, spiders will thrive.

"How do I get rid of spiders?" is a question best answered with a proactive, multi-layered approach. By focusing on Integrated Pest Management (IPM), you can create an environment that is naturally hostile to these arachnids.

Spiders prefer to live in areas where they will not be disturbed.

• Deep Vacuuming: Use specialised attachments to vacuum the junctions of walls and ceilings, behind heavy appliances, and inside air vents. This doesn't just remove the spiders; it removes their egg sacs, which can contain up to hundreds of potential offspring.
• Web Management: Consistency is key. Use a damp cloth or a long-handled brush to remove webs as soon as they appear. By repeatedly destroying their hunting grounds, you force spiders to relocate.
• Decluttering: Spiders love "dead zones"—stacks of old newspapers, cardboard boxes, and piles of unused clothes. Switching to plastic storage bins with airtight lids removes these primary hiding spots.

Physical barriers are the most effective way to stop spiders before they enter.

• Sealing the Exterior: Conduct a thorough inspection of your home’s exterior. Use high-quality silicone or acrylic sealant to plug gaps around window frames, door frames, and where utility pipes enter the wall.
• Mesh Screens: In Kenya’s climate, ventilation is essential. Ensure all windows are fitted with fine-mesh insect screens. If you have existing screens, check them for small tears that spiders could squeeze through.
• Door Sweeps: Install nylon or rubber sweeps on the bottom of all exterior doors to eliminate the narrow crawl spaces that spiders use for entry.

Your garden is the "launchpad" for a spider infestation.

• The "Vegetation Buffer": Maintain a 30cm gap between your house foundation and any plants. Ensure that tree branches and shrubs are trimmed back so they do not touch the walls or roof of your building.
• Removing Sheltering Sites: Move firewood piles, garden waste, and compost heaps away from the main structure. These are major breeding grounds for spiders and their insect prey.
• Smart Lighting: Many insects are attracted to ultraviolet light. By switching your outdoor bulbs to yellow "bug lights" or sodium vapour lamps, you reduce the number of insects congregating near your doors, which in turn reduces the number of spiders waiting to eat them.

• The Hidden Majority: For every spider you see, several more may be hidden in wall voids or ceiling cavities. Standard sprays do not reach these protected areas.
• The Lifecycle Problem: Most DIY treatments do not affect egg sacs. Once the eggs hatch, the infestation returns.
• The Rentokil Kenya Advantage: Our technicians use professional-grade formulations that have a "residual effect," meaning they continue to protect your home long after the initial application. We also offer specialised treatments for ceiling cavities—a primary refuge for spiders in Kenyan homes.
