Spiders still in basement 6 months after Ive airsealed and blockfoamed the joist bays

Ok this has me scratching my head where these little ba@#%@ are coming from
I block foamed and sealed each joist bay and sealed along the sill plate
Any ideas as I have all pertrusions sealed so I have no idea where they are coming from, surely they cant live for that long
Any ideas or pointers would be great

Darren,
Spiders aren't so bad -- they catch and eat flies and mosquitoes.

You may want to call a bugologist on this one, but I believe tarantulas can go a month or more w/out food. Too, the ones you are seeing now may be Gen 4. And, I surmise that, unless you can depressurize to -10 psi, there are still gaps big enough for young spiders to enter.

Usually spiders only set up where there is airflow for their webs to catch dinner. There are electronic plug-in devices that emit a sound humans can't hear, and that keep spiders and other critters away.
