Are there pet friendly insecticides that kill only spiders

My problem is camel crickets more than spiders.

I personally put the glue boards near the wall anyplace along the basement wall that gets wet the most often, and near the door to the outside. Basically, it's the places where I've seen evidence of them, pushed up against the wall. Under sinks and places of moisture tend to be the best locations in my experience.

As for where to get them ... um ... there's a website posted on the picture, but it looks like their catalog is more geared towards stores buying a display worth of product rather than just a few of 'em. I've seen glue boards for sale at the local Home Depot, and I've gotten them at online before.

As for the question of cover, there are some that are designed so that it gets folded up into a little triangular tent-like shape, with the glue on the inside.

When I lived in an apartment, we had a problem with fleas once (due to a neglectful pet owner in the building). Getting rid of the problem was no small feat, and took a lot of work over a few days.

I started by laundering all bedding, clothing, and basically anything fabric that was washable. Next I rented a steam cleaner, to clean the carpets. You can call in the pros for this if you don't want to do it yourself. The final step was to spray the entire carpet; paying special attention to the edges and corners, with Adams™ Flea & Tick Home Spray. Other brands exist, this was just the one I chose which worked for me.

When using any chemical spray, make sure you have adequate ventilation. Try to avoid skin contact with chemical sprays as well. My wife had a bad reaction to the spray, where her feet swelled up quite a bit.

If you're in an apartment building; where the source of the infestation could be coming from other tenants, you'll also have to treat the other units. If you don't remove the infestation from the entire building, you'll likely see the fleas return to your apartment. Any outdoor pets in the building should also be treated, not only to combat the flea infestation but also for the health of the animal.
