Spiders are considered year-round pests, but they seem to come out in full force during the summer months. Some common spiders you may encounter this summer include wolf spiders, orb weavers, garden spiders, house spiders, brown recluse spiders, and black widow spiders. While most of these are harmless, brown recluses and black widows can be dangerous to humans with their venomous bites.
The spiders you see in the summer most likely aren’t just now making their way into your home; there’s a good chance they’ve already been hiding out inside for a while. They will commonly emerge in large numbers in the summer for two main reasons:
- It’s mating season for male spiders
- It’s peak season for most of their food sources (mosquitoes, flies, ants)
Seeing a spider here and there inside your home is usually nothing to worry about; they can sneak in through open windows, doors, etc. Seeing them in large numbers, however, can indicate a much bigger problem. Spider infestations can be the result of:
- Weather. Summer weather is ideal for spiders with warm temperatures, adequate shelter, etc. If the weather gets too hot, spiders will seek relief, often inside your home. The same thing applies if the summer is overly dry or overly wet. Your home provides the perfect place to hide out until conditions outdoors improve.
- Food. If food sources outdoors become scarce (due to weather or consistent pest control around your home), spiders may make their way indoors on their search for nutrition. Conversely, if you have an infestation of other household pests that spiders like to eat, they will also come inside to take advantage of the all-you-can-eat buffet.
- Water. Spiders must have water to survive. If outdoor water sources dry up (due to drought, etc.), they will go in search of hydration indoors.
Having a spider infestation in your home can leave you with webs everywhere, the risk of spider bites that can be painful and potentially dangerous, and the possibility of other pest infestations, as well. You can keep spiders out by:
- Eliminating Entry Points. Spiders can access your home through the smallest cracks and crevices. Use weatherstripping around doors and windows and make sure it is kept in good repair. Caulk or seal any gaps, holes, and openings. Use screens on doors and windows and make sure they stay in good repair, as well.
- Eliminating Hiding Places. Spiders prefer dark, undisturbed places to hide out (corners, cabinets, closets, storage containers, piles of paper or cardboard, and cluttered areas). Declutter your home and get rid of any old papers, magazines, newspapers, and boxes. Shake out anything you haven’t used in a while before using it. Vacuum and dust regularly, especially rooms and areas that you don’t use often. Outside, trim overgrown bushes, hedges, and trees. Keep grass mowed short and mow regularly. Get rid of trash and debris in your yard that spiders can use for shelter. Store firewood and lumber away from your home.
- Eliminating Food Sources. Spiders eat other pests. Maintain routine pest control in and around your home with a professional pest control company. Eliminating other pests mean spiders will look for food elsewhere.
If you have a problem with spiders, contact your local pest control company for a thorough inspection and treatment plan.
