Outdoor lights and spiders.

Questions people ask
Is a recurring plan worth it for spiders?
For recluses, often yes. For harmless spiders, cleaning and sealing are usually enough.
What should a spider control quote include?
Which spiders they found, what they'll treat, and how often. It should say what happens if spiders return.
Is the inspection fee credited toward treatment?
Some companies credit it if you go ahead. Ask before you book. Sometimes.
How much does professional spider control cost?
Most jobs around Mobile run a few hundred dollars. Recluse work and recurring plans cost more.
How do I know if I have a black widow?
They hide under furniture, grills and meter covers. Don't handle it. Look for a shiny black spider with a red hourglass underneath.
Should I use a fogger or bug bomb for spiders?
Foggers don't reach where spiders hide. They can also be a fire risk if used wrong. No.
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.
Why are there so many spiders in my basement?
Bertone and colleagues, inspecting 50 North Carolina homes in 2012, found spiders in 92.6% of the 54 basements they searched, the highest room-level rate in the study.
Was it really a spider bite?
In Mobile, in Suchard's study of 182 patients presenting with suspected spider bites at a single California emergency department from January 2006 to November 2007, published in 2011, only 3.8% were diagnosed as spider bites, while most were infections. The useful next step in Mobile is an inspection that pins down the source rather than a guess from national numbers. Probably not.
