Power Washing & Spider Spraying

Clean the Siding First, Then Protect It for the Season

Wondering if you should power wash your house or book spider spraying? The most effective strategy is combining both. If your exterior has heavy dirt, algae, or stubborn dried-on webs, we recommend professional power washing prior to treatment—followed by Spider Squad's residual barrier to keep it web-free all season.

How Power Washing & Spider Spraying Work Together

Power washing and professional spider spraying are not competitors—they are the perfect two-step combination for total exterior home maintenance. Power washing restores the aesthetic appearance of your siding, while Spider Squad delivers the invisible chemical defense that prevents spiders from ruining your newly cleaned home.

🧼 Step 1: Deep Wash

Wash Off Dried-On Buildup

If your property has baked-on spider feces, heavy dirt, or stubborn webs stuck in stucco or brick pores, power washing or soft washing creates a pristine, clean canvas.

🛡️ Step 2: Barrier Shield

Apply Residual Protection

Once dry, Spider Squad applies a PMRA-registered micro-encapsulated barrier that bonds to siding, eaves, and window casings to stop new spiders from colonizing.

✨ The Combined Result

Long-Term Curb Appeal

Your siding stays sparkling clean and web-free for 60 to 90+ days without the frustration of spiders rebuilding webs 48 hours after washing.

When Do We Recommend Power Washing Prior to Treatment?

Every Spider Squad service includes complimentary manual web sweeping with extension brooms for loose cobwebs. However, in certain conditions, scheduling a dedicated exterior wash first is highly beneficial:

Exterior Condition Recommended Action Why It Works Best
Standard Seasonal Loose Webs Spider Squad Treatment Only Our technicians sweep down loose webs and apply the barrier in a single visit.
Heavy Dried-On Webs & Stains Power Wash First, Then Spray High-pressure washing removes baked-on silk and dirt that brooms cannot lift.
Algae, Mildew & Siding Oxidation Exterior Soft Wash First Cleans organic staining before our chemical barrier is bonded to siding.
Freshly Power-Washed Home Schedule Spray 24h Later Locks in your clean siding and prevents spiders from immediately moving back.

Frequently Asked Questions

Should I power wash my house before Spider Squad comes to spray?
If your siding has heavy grime, algae, or stubborn dried-on webs stuck to stucco or brick, we highly recommend getting your home power washed first. Once surfaces are clean and completely dry (typically 24 hours later), our technicians apply the residual barrier.
Does Spider Squad remove spider webs during service?
Yes. Every Spider Squad treatment includes high-reach manual broom sweeping for loose cobwebs and egg sacs around eaves, soffits, and window frames at no extra charge. For baked-on dirt or heavy stains, an exterior wash beforehand is recommended.
Why do spiders return so quickly after only power washing?
Power washing cleans the surface brilliantly, but leaves zero chemical residual behind. Spiders that retreated into siding weep holes or nearby foliage quickly return to build fresh webs within 24 to 48 hours. Applying Spider Squad after washing stops this cycle permanently.
How long should I wait after power washing before having my home sprayed?
We recommend waiting 24 hours after a power wash so all exterior siding, wood trim, and brick surfaces are completely dry before our micro-encapsulated barrier is applied.
