Leeks after garlic and strawberry weevils

Can I plant leeks where I've just pulled my garlic out of? It's just quite a handy space, and the only one I seem to have at the moment.

Also, I seem to have a really bad problem with strawberry weevils in my polytunnel - at least I think that's what they are. Is there any way I can fight them or should I just remove the plants completely, and can they do damage to other crops such as tomatoes, courgettes, peppers etc.?

Many thanks

 

I followed my onions last year with garlic, I know you should rotate to avoid onion white rot, but I figured, being the same year, as long as i rotate this year, should be ok. Didn't have problems & have a fine crop of parsnips there now.

 

Don't know a blind thing about strawbrary weevils
