If you're really anxious - and I know from experience that pregnancy and responsibility for babies can make one really anxious - why not get an insect net for baby's crib etc, while little one is so little. They're jolly useful - we lived in the country when my little ones were small and it kept flies and mosquitoes away and also made sure that the family cat couldn't get into the crib or pram.
available from Amazon and of course, may other places.
Good luck with baby - and with 2 year old too - good age gap
