I forgot to advocate for the spiders, again, except the really nasty ones. E.g. during damp seasons, I catch and deploy jumping spiders into my daughter’s room as a method of biological control against book lice.

In my opinion, if you have any kind of spider infestation on your property, then you have something else to worry about. Spiders need food to thrive, which usually means insects or other arthropods, which in turn means you have an infestation of other arthropods.

So why are you having a bug infestation in the first place? Are you leaving food crumbs all over the place? Do you have damp places where fungi and moss will grow? Insects and all kinds of critters really like those conditions. If you fix those, your insect and (consequently) spider infestation will most likely be gone.

In the case of mosquitoes, we are the food, so you can’t fix that, but you can clear out bodies of still water, which will decimate the number of mosquito larvae.

Killing them (with insecticides) only fixes the symptoms, not the root of the problem.
