Year-on-year organic revenue growth in the first three months of 2018 accelerated to 3.2% from 3.1% in the final quarter of 2017, when growth was affected by the impact of a hurricane in September that hit the group's operations in Puerto Rico.
The group said acquisitions had performed well in the quarter and contributed 12.5% to ongoing revenue during the period.
Ongoing revenue in the Pest Control grew by 15.8%, with organic growth of 4.7%.
On the Hygiene side of the business, ongoing revenue rose by 29.3% (1.8% organic), driven by the acquisitions of Cannon Hygiene and CWS Italy.
Ongoing revenue in Rentokil's Protect & Enhance markets declined by 0.1% (-0.3% organic), due to ongoing market weakness in the UK Property Care business, offset by a stronger performance from the French business.
Currency movements have previously been flagged as a concern and the group settled some nerves by maintaining its guidance of a £10-£15mln hit to profits from currency fluctuations over the full year.
"I am pleased with our performance in Q1 and we are well-positioned for another year of successful growth. We are confident that the company will deliver a performance in line with market expectations for 2018," said Andy Ransom, the chief executive of Rentokil.
Shares in the FTSE 100 company were up 2.3% at 279.1p in the first hour of trading.
