Questions people ask
Can I save money by doing part of the work myself?
Yes. Clear clutter and store items in sealed bins.
Does home size change the price?
Yes. Bigger homes have more walls, eaves and storage to treat.
Is the inspection fee credited toward treatment?
Some companies credit it if you go ahead. Ask before you book. Sometimes.
Is a recurring plan worth it for spiders?
Usually not for ordinary house spiders. For harmless spiders, cleaning and sealing are usually enough.
Is spider treatment safe for pets and children?
Keep kids and pets away until treated areas dry. Ask what product they'll use. Applied by the label, yes.
How long does spider treatment take to work?
You'll usually see fewer within a week or two. Webs and egg sacs need clearing too, or new spiders hatch.
Why do spiders keep coming back after I clean?
Usually because the insects they eat are still around. Egg sacs and gaps around doors also keep them coming.
