I have a ground-level apartment in Metro Detroit, Michigan and am renting. 

I have old-style baseboard radiator heat with a large opening that goes across the length of it, as shown in the photo. 

Also, there is a small gap between the laminate flooring and the wall, presumably for expansion.

As the temps are warming, I am getting spiders, ants, and possibly click beetles (can't confirm for sure if that's where they are coming from but fairly certain).

Landlord isn't helping, they insist on bug traps which don't work for me.

Last summer I covered it up with tape, but I want to avoid that this time.

Is it possible to caulk that gap between the laminate floor and wall? Does caulk give enough for expansion?

I am completely ignorant when it comes to this kind of stuff. Any suggestions are welcome.

Thanks.[![enter image description here](https://i.stack.imgur.com/ZOUAq.jpg)](https://i.stack.imgur.com/ZOUAq.jpg)
