Rated 3.0 out of 5.0 by Ralph Carpenter bees
Maybe it's good for ants or little spiders but not good for carpenter bees. I have some really annoying carpenter bees boring holes into my rake board. I called an exterminator and he wanted $600 to stuff the void with a mesh after spraying. It sounded like too much just to stuff, so I went with this. Not only did it not work but it ruined my siding. Now I have to spend money to have the rake boards replaced as well as some pieces of my siding. $600 doesn't sound too bad now. I guess I can recommend this for other types of pests. Can't if it would work for them. Good luck.

Rated 4.0 out of 5.0 by minMA Pestblock foam sealant
This was recommended by family member as alternative to regular foam sealant as this house was not well maintained by previous owners and had a lot of mice. My cats have eliminated the worst of the infestation, but the plan is to keep any more from getting in (sorry kitties!).
The only beware is the usual - this does expand, like regular foam sealants, so don't overdo it!

Worked great, use gloves for sure because this stuff is really sticky. Really happy that the house no longer has rodents!

Rated 5.0 out of 5.0 by SH Perfect for stopping mice
We had a small mouse problem when we moved in and they were smart enough to avoid the traps.
What worked? Great Stuff Pestblock Insulating Foam sprayed into all holes and gaps between your floor surface and baseboard. The foams fills the gaps perfectly and hardens overnight. So worth it. If you have exposed brick, you’ll also have holes and cracks in that. Fill them with the foam and cut away the excess after the foam has hardened. I got pretty OCD about finding every crack and hole in the (rather large) apartment and filling it, including in my laundry/utility room and all our closets. I have yet to see a mouse dropping for the last year, even though I can sometime hear them inside the brick party walls. These bottles are one-time use, so be sure to identify and clear all your holes and gaps before you start spraying. Also, this stuff is really sticky so be sure to avoid getting it on carpet and wear disposable rubber or latex gloves.

Always a good foam product. First time using the pestblock type so only time will tell if it keeps the bugs out.
