How to spider-proof a house

Updated March 23, 2017

Spiders and cobwebs in homes are not an attractive sight. While cleanliness plays a major role in controlling the eight-legged creatures, it is only one of the factors. Clean homes have spiders as well. Take steps to prevent the entry of spiders into your house.

Close holes and cracks in your house to discourage spider entry. Holes through which utility services enter your building (telephone connections and outdoor electric sockets, for example) or openings such as dryer or furnace vents are favourable vehicles for the spiders to enter your home. Use caulk to seal these openings. Check for cracks and holes around windows and doors and caulk them. Install door sweeps and keep your chimneys capped.

Trim shrubs and ornamental trees if there are any around your house foundation. Shrubs and trees that grow and start touching your siding offer avenues for spiders to crawl quickly into your home. Avoid stacking firewood or building materials against the house as this can attract spiders to build their homes next to the structure.

Clean your house thoroughly and regularly. Pay special attention to attics, basements, garages and other storage areas as well as doors, windows and vents. Keep areas along the foundation clean. Regular cleaning destroys hiding places, preventing entry of spiders.

Check for spills and scraps of food on floors and counters every day. These attract ants and flies, which in turn draw spiders. Check that sugar containers and candy dishes are well-covered as they may attract ants and flies. For the same reason, clean dishes in the sink without leaving them overnight. Move food items stored in open containers or cardboard boxes in your kitchen to tight-lidded containers to prevent ants and thus spiders.

Remove existing cobwebs and spiders. This is also part of spider-proofing your house. Vacuum your house regularly to remove spiders and their homes as well as egg sacs.
