Cockroaches phase 1

Hi can anyone Dvise of best cockroach sprays. Done all the kitchen stuff no crumbs etc but keep

comi g home in an evening to find one or two in the house I think they are coming in through the huge gap under the front door and have sprayed that but not sure if this is just normal for summer in Spain 

after saying that this is our fourth summer here but first on phase 1 and never had problems in the past 

thanks

Find one (if you can) that says that it works for 6 months. These have the best killing effect. The best one we've found is made by Bloom but is extremely hard to find. Having said that the one available in Mercadona works fine.

Spray along the end of the door and all along the outer walkway if you think that is where they are getting in.

We've owned since original build and this is the fisrt summer we've seen any in the apartment. And they appeared as soon as they'd sprayed down all the drains for roaches several weeks ago.
And we think the ones we found (stuck in the 2nd bathroom) must have come down through the ceiling fan or up through the drains.

It may also be worth advising Resortalia of the problem as other people on Phase 1 could be affected and things might need to br sprayed again. Although they will naturally die off in a few weeks.

As you say, Summer in Spain can be a real pain for them.

Thank you - bloom searching I will go and will also notify resortalia

thanks again
